RAM with a frequency of 2133 MHz. Tests of six DDR3 memory kits: in pursuit of speed. Memory capacity for older PCs

The question of comparing DDR4-2133 vs DDR4-2400 has been haunting us since the winter, when Intel Kaby Lake processors with DDR4-2400 support appeared, and many at least had the desire to overclock the existing DDR4-2133 modules or buy the most budget DDR4-2400 for this. This does not mean that higher frequencies are not supported, just that anything higher is already overclocking, which mainly requires motherboards based on Intel Z170 or Z270 chipsets, as well as processors with an unlocked multiplier.

If you have a build on Intel H110, B150 or H170, for which you bought a Kaby Lake processor, then after BIOS updates it must support DDR4-2400 memory, because the RAM controller is located directly in the processor itself. Therefore, if you have a board from a reputable manufacturer, then after flashing there should be no problems: just go to the BIOS and select the desired memory frequency, as we did on the ASRock H110M-HDS board. You can select timings yourself or trust the system.

To evaluate the usefulness of this action, we decided to conduct four short test sessions. The first two will be on a budget system that includes an Intel Pentium G4560 processor, 8 GB of RAM and an integrated Intel HD Graphics 610 graphics core or a SAPPHIRE NITRO+ Radeon RX 470 4GB video card. The other two will use a more powerful configuration based on the Core i7-6700K and 16 GB of RAM. In this case, either the built-in Intel HD Graphics 530 core or the Colorful GTX 1060 SI-6G video card will be responsible for graphics processing.

Assembly on Intel Pentium:

• Intel Pentium G4560
• ASRock H110M-HDS
• SAPPHIRE NITRO+ Radeon RX 470 4GB
• 2x4GB DDR4-2133 Transcend TS512MLH64V1H
• WD Blue Desktop 2 TB (WD20EZRZ)
• AeroCool VX500 500W
• GameMax MT521-NP
• AVerMedia Live Gamer HD
• AVerMedia Live Gamer Portable 2

System on Intel Core i7:

• Intel Core i7-6700K (OC 4.5 GHz)
• Thermaltake Water 3.0 Riing RGB 240
• ASUS MAXIMUS VIII RANGER
• 2 x 8 GB DDR4-3200 G.SKILL Trident Z
• Colorful GTX 1060 SI-6G
• SSHD Seagate ST2000DX001 2TB
• HDD WD WD1000DHTZ 1TB
• Seasonic Snow Silent 1050 1050W
• Thermaltake Core P3
• ASUS VH228H
• AVerMedia Live Gamer HD

So, let's start with the Intel Pentium G4560 and integrated graphics. DiRT Rally in HD resolution with a very low graphics preset provides very comfortable performance in both cases. However, when moving from DDR4-2133 to 2400, the average FPS increases from 95 to 98 fps, and the minimum - from 75 to 77. The difference is 3%.

Rainbow Six Siege already heavier, so even with a low profile in HD resolution the difference in absolute performance is almost not felt, because it is less than 1 FPS. If we go to relative units, then the system with faster memory wins 0.4% on average and loses 6% on the minimum.

For start Far Cry Primal a low graphics preset and HD resolution were also used. In both cases, we received a slide show, but with an advantage of 1 FPS in favor of DDR4-2400 memory: 13 versus 12 fps on average and 12 versus 11 on minimum. In relative units this is about 8-9% bonus.

Now we move on to the second session, where we paired the Intel Pentium G4560 with an RX 470 series video card. And we overclocked the memory to 2400 MHz in two ways: with automatic selection of timings, which in our case corresponds to the CL17 scheme, or with manual installation CL15 circuits. Let's find out if Full HD resolution is beneficial.

The first surprise awaited us in DiRT Rally with a very high graphics preset. According to the results of the test, the system with DDR4-2133 memory unexpectedly took the lead with an average frequency of 101 FPS and drops of up to 78. In second place was a configuration with 2400 memory and CL15 delays, which produced an average of 99 frames/s with drops of up to 68. Results of the third configurations were 98 and 67 FPS, respectively. At the same time, the tests were run several times, but the trend persisted.

High profile graphics settings in Rise of the Tomb Raider leads to a change in the leader in the overall average, although the difference between first and third place does not exceed 1 FPS. Nevertheless, this test turned out to be for DDR4-2400 memory with CL17 timings, the second result was shown by DDR4-2133, and the third - by DDR4-2400 CL15. At a minimum, practice matches theory: that is, higher frequencies and lower delays provide better performance.

Benchmark Far Cry Primal at ultra settings, I agree with DiRT Rally that the combination with DDR4-2133 memory should be in the lead with an average result of 54 frames/s and drops to 43. But the timing scheme does not play a special role for it, so both competing systems are with DDR4 -2400 showed the same results: an average of 49 with drops to 38 FPS.

The last one in this session will be Ghost Recon Wildlands with a high graphics preset. On average, the best result of 60 FPS was produced by a system with DDR4-2400 and CL15 latencies. In second place with 59 frames/s was the combination with DDR4-2133, and the third result was for DDR4-2400 CL17. According to the minimum indicator, the opposite is true: the best result is for DDR4-2400 CL17, the worst is for DDR4-2400 CL15.

In the third part, we switched to an Intel Core i7-6700K and limited ourselves to the built-in Intel HD Graphics 530 adapter. Therefore, the tests were carried out in HD resolution.

DiRT Rally with medium settings, I gave a clear preference to faster memory: 44 versus 41 FPS on the average and 38 versus 35 on the minimum. The difference was approaching 8%.

Rainbow Six Siege with a low preset, I agree with this state of affairs, but assess the advantage of DDR4-2400 memory more modestly: the increase in the average indicator was about 4%, and the minimum - about 2%.

And here For Honor with a low profile, I couldn’t determine a clear winner: in terms of the average indicator, the system with faster memory took the lead, and in terms of the minimum indicator, the configuration with DDR4-2133 memory retained the lead. Although in both cases the difference did not exceed 1 FPS.

And the final test session was carried out using a combination of an Intel Core i7-6700K processor and a GeForce GTX 1060 video card, so the resolution was increased to Full HD.

Rise of the Tomb Raider with a very high preset, it gives minimal preference to the system with faster memory on average. In terms of the minimum frame rate, the difference between DDR4-2400 and 2133 already reaches 9 frames/s or 34%.

And here Far Cry Primal With ultra settings, I decided not to take sides, giving both systems the same results: 67 FPS with drawdowns of up to 53. Only the percentage of memory used and maximum FPS indicate a slight advantage of DDR4-2400.

And in Ghost Recon Wildlands at a very high profile, we again see a minimal advantage of faster memory: the difference in average and minimum speed does not exceed 1 FPS. But at the same time, the average load on the processor in the case of DDR4-2400 decreased by 4%.

Results

As a result, we see that in terms of gaming performance, overclocking memory from DDR4-2133 to 2400 on Intel platforms does not always give a noticeable result. In a budget system, a positive effect can only be counted on when using built-in graphics. Yes, the increase can reach 8-9%, but you can’t play particularly demanding projects on the HD Graphics 610. And if you add a discrete video card to such a system, then higher results in some tests can be obtained with DDR4-2133 memory, rather than 2400. With lower timings, you also cannot always count on a noticeable bonus.

In a productive configuration on Intel based Core i7 practical tests are more in line with theory: in almost all cases, the combination with faster memory looks better, but the difference is still small. With integrated graphics, we received a bonus of 3-8%, but for this we will have to lower the graphics settings and switch to HD resolution. WITH discrete video card the increase is mainly within the measurement error level, if you do not take into account the result in Rise of the Tomb Raider.

RAM is used to temporarily store data necessary for the operation of the operating system and all programs. There should be enough RAM; if there is not enough, the computer starts to slow down.

The board with memory chips is called a memory module (or stick). Memory for a laptop, except for the size of the slots, is no different from memory for a computer, so when choosing, follow the same recommendations.

For an office computer, one 4 GB DDR4 stick with a frequency of 2400 or 2666 MHz is enough (costs almost the same).
RAM Crucial CT4G4DFS824A

For multimedia computer(movies, simple games) it is better to take two 4 GB DDR4 sticks with a frequency of 2666 MHz, then the memory will work in a faster dual-channel mode.
RAM Ballistix BLS2C4G4D240FSB

For a mid-class gaming computer, you can take one 8 GB DDR4 stick with a frequency of 2666 MHz so that in the future you can add another one, and it would be better if it is a simpler running model.
RAM Crucial CT8G4DFS824A

And for a powerful gaming or professional PC, you need to immediately take a set of 2 DDR4 8 GB sticks, and a frequency of 2666 MHz will be quite sufficient.

2. How much memory is needed

For an office computer designed for working with documents and accessing the Internet, one 4 GB memory stick is sufficient.

For a multimedia computer that can be used to watch high-quality videos and undemanding games, 8 GB of memory is sufficient.

For a mid-range gaming computer, the minimum option is 8 GB of RAM.

A powerful gaming or professional computer requires 16 GB of memory.

A larger amount of memory may be needed only for very demanding professional programs and is not needed by ordinary users.

Memory capacity for older PCs

If you decide to increase the memory on your old computer, please note that 32-bit versions of Windows do not support more than 3 GB random access memory. That is, if you install 4 GB of RAM, the operating system will see and use only 3 GB.

As for 64-bit versions of Windows, they will be able to use all installed memory, but if you have an old computer or an old printer, then they may not have drivers for these operating systems. In this case, before purchasing memory, install 64-bit Windows version and check if everything works for you. I also recommend looking at the website of the motherboard manufacturer and seeing what volume of modules and total amount of memory it supports.

Please also note that 64-bit operating systems consume 2 times more memory, for example, Windows 7 x64 takes about 800 MB for its needs. Therefore, 2 GB of memory for such a system will not be enough, preferably at least 4 GB.

Practice shows that modern operating systems Windows 7,8,10 are fully operational with a memory capacity of 8 GB. The system becomes more responsive, programs open faster, and jerks (freezes) disappear in games.

3. Memory types

Modern memory is of the DDR SDRAM type and is constantly being improved. So DDR and DDR2 memory is already obsolete and can only be used on older computers. DDR3 memory is no longer advisable to use on new PCs; it has been replaced by the faster and more promising DDR4.

Please note that the selected memory type must be supported by the processor and motherboard.

Also, new processors, for compatibility reasons, can support DDR3L memory, which differs from regular DDR3 in reduced voltage from 1.5 to 1.35 V. Such processors will be able to work with regular DDR3 memory if you already have it, but processor manufacturers do not recommend this because -due to increased degradation of memory controllers designed for DDR4 with an even lower voltage of 1.2 V.

Memory type for older PCs

Outdated DDR2 memory costs several times more than more modern memory. A 2 GB DDR2 stick costs 2 times more, and a 4 GB DDR2 stick costs 4 times more than a DDR3 or DDR4 stick of the same size.

Therefore, if you want to significantly increase the memory on an old computer, then perhaps the best option would be to switch to a more modern platform by replacing the motherboard and, if necessary, a processor that will support DDR4 memory.

Calculate how much it will cost you; perhaps a profitable solution would be to sell the old one motherboard with old memory and purchase new, albeit not the most expensive, but more modern components.

The motherboard connectors for installing memory are called slots.

Each memory type (DDR, DDR2, DDR3, DDR4) has its own slot. DDR3 memory can only be installed in a motherboard with DDR3 slots, DDR4 - with DDR4 slots. Motherboards supporting old memory DDR2 is no longer produced.

5. Memory characteristics

The main characteristics of memory on which its performance depends are frequency and timings. Memory speed does not have as strong an impact on the overall performance of the computer as the processor. However, you can often get faster memory for not much more. Fast memory is needed primarily for powerful professional computers.

5.1. Memory frequency

Frequency has the greatest impact on memory speed. But before purchasing it, you need to make sure that the processor and motherboard also support the required frequency. Otherwise, the actual memory operating frequency will be lower and you will simply overpay for something that will not be used.

Inexpensive motherboards support lower maximum memory frequencies, for example for DDR4 it is 2400 MHz. Mid-range and high-end motherboards can support higher frequency memory (3400-3600 MHz).

But with processors the situation is different. Older processors with DDR3 memory support may support memory with a maximum frequency of 1333, 1600, or 1866 MHz (depending on the model). For modern processors that support DDR4 memory, the maximum supported memory frequency may be 2400 MHz or higher.

Intel 6th generation and higher processors and AMD Ryzen processors support DDR4 memory at 2400 MHz or higher. Moreover, their lineup includes not only powerful expensive processors, but also mid-range and budget-class processors. Thus, you can build a computer on the most modern platform with an inexpensive processor and DDR4 memory, and in the future change the processor and get the highest performance.

The main memory today is DDR4 2400 MHz, which is supported by the most modern processors, motherboards and costs the same as DDR4 2133 MHz. Therefore, purchasing DDR4 memory with a frequency of 2133 MHz today does not make sense.

You can find out what memory frequency a particular processor supports on the manufacturers’ websites:

By model number or serial number it is very easy to find all the characteristics of any processor on the website:

Or just enter the model number in the search engine Google system or Yandex (for example, “Ryzen 7 1800X”).

5.2. High Frequency Memory

Now I want to touch on another interesting point. On sale you can find RAM at a much higher frequency than can be supported by any modern processor(3000-3600 MHz and above). Accordingly, many users are wondering how this can be?

It's all about a technology developed by Intel, eXtreme Memory Profile (XMP). XMP allows memory to run at a higher frequency than the processor officially supports. XMP must be supported by both the memory itself and the motherboard. High frequency memory simply cannot exist without support for this technology, but not all motherboards can boast of its support. These are mainly more expensive models above the middle class.

The essence of XMP technology is that the motherboard automatically increases the frequency of the memory bus, due to which the memory begins to operate at its higher frequency.

AMD has a similar technology called AMD Memory Profile (AMP), which was supported by older AMD processor motherboards. These motherboards usually also supported XMP modules.

Purchasing more expensive memory with a very high frequency and a motherboard with XMP support makes sense for very powerful professional computers equipped with a top-end processor. In a middle-class computer, this will be wasted money, since everything will depend on the performance of other components.

In games, the memory frequency has a small impact and there is no point in overpaying; it will be enough to go for 2400 MHz, or 2666 MHz if the difference in price is small.

For professional applications, you can take memory with a higher frequency - 2666 MHz or, if you want and have funds, 3000 MHz. The difference in performance here is greater than in games, but not dramatic, so there is no particular point in pushing the memory frequency.

Let me remind you once again that your motherboard must support memory at the required frequency. In addition, sometimes Intel processors become unstable at memory frequencies above 3000 MHz, and for Ryzen this limit is around 2900 MHz.

Timings are the delays between read/write/copy operations of data in RAM. Accordingly, the fewer these delays, the better. But timings have a much smaller impact on memory speed than its frequency.

There are only 4 main timings that are indicated in the characteristics of memory modules.

Of these, the most important is the first number, which is called latency (CL).

Typical latency for DDR3 1333 MHz memory is CL 9, for higher frequency DDR3 memory is CL 11.

Typical latency for DDR4 2133 MHz memory is CL 15, for DDR4 memory with a higher frequency is CL 16.

You should not purchase memory with a latency higher than specified, as this indicates an overall low level of its technical characteristics.

Typically, memory with lower timings is more expensive, but if the price difference is not significant, then memory with lower latency should be preferred.

5.4. Supply voltage

Memory may have different supply voltages. It can be either standard (generally accepted for a certain type of memory), or increased (for enthusiasts) or, conversely, reduced.

This is especially important if you want to add memory to your computer or laptop. In this case, the voltage of the new strips should be the same as the existing ones. Otherwise, problems are possible, since most motherboards cannot set different voltages for different modules.

If the voltage is set to a level with a lower voltage, then others may not have enough power and the system will not work stably. If the voltage is set to a level with a higher voltage, then the memory designed for a lower voltage may fail.

If you are collecting new computer, then this is not so important, but to avoid possible problems compatibility with motherboard and replacing or expanding memory in the future, it is better to choose sticks with a standard supply voltage.

The memory, depending on the type, has the following standard supply voltages:

• DDR - 2.5 V
• DDR2 - 1.8 V
• DDR3 - 1.5 V
• DDR3L - 1.35 V
• DDR4 - 1.2 V

I think you noticed that there is DDR3L memory in the list. This is not a new type of memory, but regular DDR3, but with a reduced supply voltage (Low). This is the kind of memory needed for 6th generation Intel processors and higher, which support both DDR4 and DDR3 memory. But in this case, it is better to build the system on new DDR4 memory.

6. Marking of memory modules

Memory modules are marked depending on the type of memory and its frequency. The marking of DDR memory modules begins with PC, followed by a number indicating the generation and speed in megabytes per second (MB/s).

Such markings are inconvenient to navigate; it is enough to know the type of memory (DDR, DDR2, DDR3, DDR4), its frequency and latency. But sometimes, for example on ad sites, you can see markings copied from the strip. Therefore, so that you can get your bearings in this case, I will give the markings in a classic form, indicating the type of memory, its frequency and typical latency.

DDR - obsolete

• PC-2100 (DDR 266 MHz) - CL 2.5
• PC-2700 (DDR 333 MHz) - CL 2.5
• PC-3200 (DDR 400 MHz) - CL 2.5

DDR2 - obsolete

• PC2-4200 (DDR2 533 MHz) - CL 5
• PC2-5300 (DDR2 667 MHz) - CL 5
• PC2-6400 (DDR2 800 MHz) - CL 5
• PC2-8500 (DDR2 1066 MHz) - CL 5

DDR3 - obsolete

• PC3-10600 (DDR3 1333 MHz) - CL 9
• PC3-12800 (DDR3 1600 MHz) - CL 11
• PC3-14400 (DDR3 1866 MHz) - CL 11
• PC3-16000 (DDR3 2000 MHz) - CL 11

• PC4-17000 (DDR4 2133 MHz) - CL 15
• PC4-19200 (DDR4 2400 MHz) - CL 16
• PC4-21300 (DDR4 2666 MHz) - CL 16
• PC4-24000 (DDR4 3000 MHz) - CL 16
• PC4-25600 (DDR4 3200 MHz) - CL 16

DDR3 and DDR4 memory may have a higher frequency, but only top processors and more expensive motherboards can work with it.

7. Design of memory modules

Memory sticks can be single-sided, double-sided, with or without radiators.

7.1. Chip placement

Chips on memory modules can be placed on one side of the board (single-sided) or on both sides (double-sided).

This doesn't matter if you are purchasing memory for a new computer. If you want to add memory to an old PC, then it is advisable that the arrangement of chips on the new stick be the same as on the old one. This will help avoid compatibility issues and increase the likelihood of memory operating in dual-channel mode, which we will talk about later in this article.

Now on sale you can find many memory modules with aluminum radiators of various colors and shapes.

The presence of heatsinks can be justified on DDR3 memory with a high frequency (1866 MHz or more), since it heats up more. At the same time, ventilation must be well organized in the housing.

Modern DDR4 RAM with a frequency of 2400, 2666 MHz practically does not heat up and the radiators on it will be purely decorative. They can even get in the way, because after a while they become clogged with dust, which is difficult to clean out of them. In addition, such memory will cost somewhat more. So, if you want, you can save on this, for example, by taking excellent Crucial 2400 MHz memory without heatsinks.

Memory with a frequency of 3000 MHz or more also has an increased supply voltage, but it also does not heat up very much and in any case there will be heatsinks on it.

8. Memory for laptops

Memory for laptops differs from memory for desktop computers only in the size of the memory module and is labeled SO-DIMM DDR. Just like for desktop computers, memory for laptops has types DDR, DDR2, DDR3, DDR3L, DDR4.

In terms of frequency, timings and supply voltage, memory for laptops does not differ from memory for computers. But laptops only come with 1 or 2 memory slots and have stricter maximum capacity limits. Be sure to check these parameters before choosing memory for specific model laptop.

9. Memory operating modes

The memory can operate in Single Channel, Dual Channel, Triple Channel or Quad Channel mode.

In single-channel mode, data is written sequentially to each module. In multi-channel modes, data is written in parallel to all modules, which leads to a significant increase in the speed of the memory subsystem.

Single-channel memory mode is limited only to hopelessly outdated motherboards with DDR memory and the first models with DDR2.

All modern motherboards support dual-channel memory mode, while three-channel and quad-channel modes are supported only by a few models of very expensive motherboards.

The main condition for dual-channel mode operation is the presence of 2 or 4 memory sticks. Three-channel mode requires 3 or 6 memory sticks, and four-channel mode requires 4 or 8 memory sticks.

It is desirable that all memory modules are the same. Otherwise, dual-channel operation is not guaranteed.

If you want to add memory to an old computer and your motherboard supports dual-channel mode, try to choose a stick that is as identical in all respects as possible. It is best to sell the old one and buy 2 new identical strips.

In modern computers, memory controllers have been moved from the motherboard to the processor. Now it is not so important that the memory modules are the same, since the processor will still be able to activate dual-channel mode in most cases. This means that if you want to add more memory in the future modern computer, then you won’t have to look for exactly the same module; it’s enough to choose the one with the most similar characteristics. But I still recommend that the memory modules be the same. This will give you a guarantee of its fast and stable operation.

With the transfer of memory controllers to the processor, 2 more modes of dual-channel memory operation appeared - Ganged (paired) and Unganged (unpaired). If the memory modules are the same, the processor can work with them in Ganged mode, as before. If the modules differ in characteristics, the processor can activate the Unganged mode to eliminate distortions in working with memory. In general, the memory speed in these modes is almost the same and makes no difference.

The only downside to dual-channel mode is that multiple memory modules are more expensive than one of the same size. But if you are not very strapped for money, then buy 2 sticks, the memory speed will be much higher.

If you need, say, 16 GB of RAM, but you can’t afford it yet, then you can buy one 8 GB stick so that you can add another one of the same kind in the future. But it is still better to purchase two identical strips at once, since later you may not be able to find the same one and you will encounter a compatibility problem.

10. Memory module manufacturers

One of the best price/quality ratios today comes from the memory of the impeccably proven Crucial brand, which has modules from budget to gaming (Ballistix).

Competing with it is the well-deserved Corsair brand, whose memory is somewhat more expensive.

As an inexpensive but high-quality alternative, I especially recommend the Polish brand Goodram, which has bars with low timings at a low price (Play line).

For an inexpensive office computer, simple and reliable memory made by AMD or Transcend will be sufficient. They have proven themselves to be excellent and there are practically no problems with them.

In general, the Korean companies Hynix and Samsung are considered leaders in memory production. But now modules of these brands are mass-produced in cheap Chinese factories, and among them there are a lot of fakes. Therefore, I do not recommend purchasing memory from these brands.

An exception may be Hynix Original and Samsung Original memory modules, which are manufactured in Korea. These strips are usually blue, their quality is considered better than those made in China and the guarantee for them is slightly higher. But in terms of speed characteristics, they are inferior to memory with lower timings from other quality brands.

Well, for enthusiasts and fans of modding there are affordable overclocking brands GeIL, G.Skill, Team. Their memory has low timings, high overclocking potential, an unusual appearance and costs a little less than the well-promoted Corsair brand.

There is also a wide range of memory modules on sale from the very popular manufacturer Kingston. Memory sold under the budget Kingston brand has never been of high quality. But they have a top-end HyperX series, which is deservedly popular, which can be recommended for purchase, but is often overpriced.

11. Memory packaging

It is better to purchase memory in individual packaging.

Usually she is more High Quality and the likelihood of damage during transportation is much lower than with memory that comes unpackaged.

12. Increase memory

If you are planning to add memory to an existing computer or laptop, then first find out what the maximum memory capacity and total memory capacity is supported by your motherboard or laptop.

Also check how many memory slots are on the motherboard or laptop, how many of them are occupied and what kind of memory sticks are installed in them. It's better to do it visually. Open the case, take out the memory sticks, examine them and write down all the characteristics (or take a photo).

If for some reason you don’t want to get into the case, you can view the memory parameters in the program on the SPD tab. This way you won't know if the stick is single-sided or double-sided, but you can find out the memory characteristics if there is no sticker on the stick.

There is a base and effective memory frequency. The CPU-Z program and many similar ones show the base frequency, it must be multiplied by 2.

Once you know how much memory you can increase, how many free slots are available, and what kind of memory you have installed, you can begin to explore the possibilities of increasing memory.

If all memory slots are occupied, then the only way to increase memory is to replace existing memory sticks with new ones of larger capacity. And old planks can be sold on an advertisement site or exchanged at computer store when buying new ones.

If there are free slots, then you can add new memory sticks to the existing ones. In this case, it is desirable that the new strips be as close as possible to the characteristics of those already installed. In this case, you can avoid various compatibility problems and increase the chances that the memory will work in dual-channel mode. To do this, the following conditions must be met, in order of importance.

1. The memory type must match (DDR, DDR2, DDR3, DDR3L, DDR4).
2. The supply voltage for all strips must be the same.
3. All planks must be single-sided or double-sided.
4. The frequency of all bars must match.
5. All strips must be of the same volume (for dual-channel mode).
6. The number of strips must be even: 2, 4 (for dual-channel mode).
7. It is desirable that the latency (CL) matches.
8. It is desirable that the strips are from the same manufacturer.

The easiest place to start choosing is with the manufacturer. Choose in the online store catalog strips of the same manufacturer, volume and frequency as installed in yours. Make sure that the supply voltage matches and check with your consultant whether they are single-sided or double-sided. If the latency also matches, then generally good.

If you were unable to find strips from the same manufacturer with similar characteristics, then choose all the others from the list of recommended ones. Then again look for strips of the required volume and frequency, check the supply voltage and check whether they are single-sided or double-sided. If you are unable to find similar planks, then look in another store, catalog or ad site.

The best option is always to sell all the old memory and buy 2 new identical sticks. If the motherboard does not support the brackets of the required volume, you may have to buy 4 identical brackets.

13. Setting up filters in the online store

1. Go to the “RAM” section on the seller’s website.
2. Select recommended manufacturers.
3. Select the form factor (DIMM - PC, SO-DIMM - laptop).
4. Select the memory type (DDR3, DDR3L, DDR4).
5. Select the required volume of slats (2, 4, 8 GB).
6. Select the maximum frequency supported by the processor (1600, 1866, 2133, 2400 MHz).
7. If your motherboard supports XMP, add higher frequency memory (2666, 3000 MHz) to the selection.
8. Sort the selection by price.
9. Consistently look through all items, starting with the cheapest ones.
10. Select several strips that match the frequency.
11. If the price difference is acceptable to you, take sticks with a higher frequency and lower latency (CL).

Thus, you will get the optimal price/quality/speed ratio of memory at the lowest possible cost.

Actually, this note was supposed to be short, but since the tests took me some time, let it be a little longer.

It all started with the transition to a motherboard with DDR3. I don’t even remember how many years ago it was. Then, with the motherboard, I immediately took two Patriot sticks of 2 GB each with a frequency of 1600 MHz from Khlama.net (by the way, they were not overclocked at all - it was impossible to take them above 1600).

The total was 4 GB. In those days it was "a lot." Then I gradually changed three motherboards and 4-GB sticks began to appear on sale. And I wanted to “upgrade”. It just so happened that at the moment when I bought a pair of 4-gigabyte strips, there were no optimal prices for 1600-frequency ones, and I took the usual Patriot at 1333 MHz from the “Monitor” (it became 8 GB). A month later, for the sake of experiment, I took another pair of the same strips (now 16 GB). Fortunately, the motherboard supports up to 32 GB. These 1333 strips were consistently overclocked without increasing timings or increasing voltage to 1600 MHz. But no higher.

And on Saturday I bought two 4 GB DDR3 sticks from Hynix (Hyundai Electronics). They turned out to have the batch number HMT351U6CFR8C-H9, which was noted on the overclockers.ru forums

http://forums.overclockers.ru/viewtopic.php?f=111&t=292041

Batch - HMT351U6CFR8C-H9.

This batch is famous for the fact that in most cases it is capable of overclocking from the “native” 1333 MHz to a stable 2133 MHz.

To my joy, this particular batch was available for free sale in one of the stores in Yakutsk.

The bar is produced without radiators, but what is interesting to note is that it does not heat up at all (including at 100% test load) either at a nominal frequency of 1333 MHz (1.50 V) or at 2133 MHz (1.59 V) . It turns out that in this case radiators are not needed here.

For example, here’s what an over from the overclockers forum wrote about this memory:

Hynix Original DDR3 PC3-10600

Nominal: (1333 MHz) 9-9-9-27 1.50v

Overclocking: (1866 Mhz) 9-10-9-30 1.55v

Overclocking: (2133 Mhz) 10-12-11-30 1.57v

Overclocking MAX: when raising vccio to 1.120v takes (2271mhz) 11-12-11-30 1.59v

I placed two Hynix strips in dual-channel mode. And immediately before the first launch I cleared the CMOS. I went into Windows and looked in CPU-Z - the memory was detected correctly.

Then I rebooted and set the memory frequency to 2133 MHz with a voltage of 1.59 V (they wrote on the forum that this voltage is more than enough in most cases) and “gentle” timings of 11-12-11-30-2T (again, in most cases the data I set the timings with a “reserve”). By the way, I must immediately write that I will “work” only on the 4 main timings, which most strongly affect memory performance.

Everything started - I logged into Windows. Since I only had LinX among the latest stress test programs that use RAM, I decided to use only it in tests for the first time. However, it is common knowledge that no program can UNIQUELY and quickly identify memory errors. It is imperative to test for a long time on various types of stress programs that make good use of the RAM in their work. For example, in the “Memory Testing Methodology” thread on overclockers.ru they recommend - [hereinafter - list of programs]

In the test, LinX used 6500 MB of memory out of the installed 8 GB.

Duration - 10 passes.

Control of all voltages, all types of frequencies, memory timings and temperatures - CPU-Zx64 1.59, ASRock eXtreme Tuner 0.1.54, Core Temp 0.99.8.

Then he sharply reduced all timings by one.

10-11-10-29-2T - passage No. 7 linpack failed.

10-11-10-30-2T - the linpak passed all 10 passes.

9-11-10-30-2T - does not come in.

10-10-10-30-2T - does not enter.

10-11-9-30-2T - BSOD occurs upon entry.

10-11-10-30-1T - passage No. 4 linpack failed.

That. I found out that in the case of a stress load with a linpack, the minimum timings at a frequency of 2133 MHz that ensure stability are the following numbers: 10-11-10-30-2T.

On Sunday I went to the store and bought a second set of the same planks: 2 pcs. x 4 GB.

His details:

HMT351U6CFR8C-H9 - the same batch as in the top set, differing only in the week of release.

I'm testing the second set.

At nominal: 1333 MHz, 9-9-9-25, 1.50 V.

The voltage for timing overclocking was increased to 1.59 V.

Frequency - 2133 MHz.

11-12-11-30-2T - enters Windows, not tested

10-11-10-30-2T - does not enter

11-11-10-30-2T - does not enter

11-11-11-30-2T - does not enter

11-12-11-30-2T - passed all passes stably.

Now I’ll test all four strips: “set_1” + “set_2”

At face value: 9-9-9-25, 1.50 V - everything is stable. Everything starts and works, however, that’s how it should be - since there is no overclocking.

I also made clear_cmos after installing all 4 modules on the motherboard.

The voltage for timing overclocking was again increased to 1.59 V.

Frequency - 2133 MHz. Timings - 11-12-11-30-2T. Don `t come in.

Frequency - 2133 MHz. Timings - 12-13-12-35-2T. Don `t come in.

The frequency overclocking was reduced to the native 1333 MHz.

1333 MHz, 11-12-11-30-2T. Still won't log in.

1333 MHz, 10-11-10-30-2T. Logs into Windows.

1600 MHz, 10-11-10-30-2T. Logs into Windows.

1866 MHz, 10-11-10-30-2T. Logs into Windows.

An attempt to increase the first timing by one leads to a complete stop. The computer goes into unconsciousness.

The same garbage when changing the second and third timings. Those. they cannot be increased. You can't reduce it either. Increasing the memory voltage to 1.7 does not help at all. I didn’t touch the fourth timing at all - let it remain that way.

Thus, the acceleration for four strips came to only one end:

1866 MHz, 10-11-10-30-2T. I reduced the voltage from 1.59 to 1.56 V. I'll try to test at this voltage. Everything seems to be fine so far.

Test computer configuration:

Processor Intel Core i5 2500K, 4600 MHz, 1,350 V;

Cooler ThermalRight Silver Arrow, TR TY-140 x 2 pcs. x 1300 rpm;

Motherboard ASRock P67 Extreme6 P67 (bios P1.60);

Memory DDR3, 2 x 4 Gb 1333 MHz, Hynix HMT351U6CFR8C-H9, 1.50 V, 9-9-9-25;

Hard drive 500Gb, WD5000AAKS (SATA2, 7200 rpm, 16 Mb);

Lian Li PC-A70FB case, and 4 original built-in fans + open side wall;

Reobass Zalman ZM-MFC1 Plus;

PSU AeroCool Strike-X 1100 (1100 W, 80+ Gold);

Video Inno 3D Geforce GTX570 (732/1464/3800, 1,000 V) - reference CO replaced with DeepCool V6000;

Monitor 24" Acer P246H 1920*1080.

Calculations:

2133/1333 = 1.6 - 60% increase in frequency.

1866/1333 = 1.4 - 40% increase in frequency.

Overclocking from 1333 MHz to 2133 is technically and practically justified, despite a slight increase in timings. Causes:

Increasing the frequency by 40%-60% affects the increase in memory performance more than increasing the timings;

Increasing the voltage from the “native” 1.50 to 1.55-1.59 V does not lead to heating of the memory chips (even under long-term loads);

The cost of standard DDR3 memory in 4 GB sticks from Hynix is ​​extremely low (700 rubles). This is especially noticeable when compared with branded overclocked memory sticks, which have increased voltage (up to 1.65 V and higher) and prices are at least times higher (especially sticks with frequencies of 1866-2133 MHz). Although they can be justified by:

a) a well-fitted radiator, which is both beautiful and provides proper heat dissipation;

b) selection of planks in factories - i.e. theoretically they have a higher chance of higher overclocking.

Rumors that obviously overclockable strips, when installed in four pieces, lose their frequency potential - have been confirmed. This is actually true.

III. Of course, a 60% increase in frequency is a very good result.

But is he so good “in life”, so to speak?..

In synthetics there will definitely be an increase, and in practical applications, I think there will be, but not 60%, of course.

In general, we'll see. I'll write back after the tests.

Now the question follows - “What will I do with the slats?”

Reviews of new memory modules appear on our website quite regularly. This time we will test high-speed dual-channel DDR3 memory sets with a total capacity of 16 GB. A distinctive feature of all these kits is the presence of Intel XMP profiles (Extreme Memory Profiles), which can be used on motherboards for Intel processors with support for XMP profiles.

Instead of a preface to this review, I would like to make a few comments regarding modern DDR3 memory.

As you know, almost all memory module manufacturers offer a very wide range of products aimed at various categories of users. This includes regular memory, gaming memory, and memory for overclockers. Let us remember that there are not many manufacturers of memory chips themselves: the industry leaders are companies such as Samsung, Micron and Hynix. It is clear that module manufacturers do not have such a large choice. So where does such a wide range of products come from?

Of course, all these different memory series are pure marketing. Memory modules belonging to different series may have exactly the same characteristics (and even the same memory chips) and differ only in the color of the heatsink. By the way, the heatsinks themselves on memory modules are a purely decorative and, by and large, meaningless thing. Well, memory chips don’t get so hot that they require cooling using radiators! Let's not be unfounded and confirm what has been said with facts.

In order to demonstrate the pointlessness of heatsinks on memory modules, we used a pyrometer that allows us to remotely determine temperature changes. One time we used a DDR3-2400 memory module with a heatsink, and another time without it. The supply voltage was 1.65 V (standard supply voltage is 1.5 V). To load memory, we used the Stress System Memory stress test in the AIDA64 utility. The results of our measurement are as follows. When memory operates with a heatsink, the heatsink temperature increases by 7-8 °C in memory loading mode compared to the temperature in idle mode. When a memory module operates without a heatsink, the temperature of the memory chips increases by 15-16 °C in memory loading mode compared to the temperature in idle mode. It would seem that a difference of 7 °C is not so small. But the whole point is that the absolute temperature of memory chips in their stress loading mode is only 45-46 °C, which is absolutely uncritical for the microcircuit.

Of course, you can try to overclock the memory even more by applying a higher voltage and increasing the frequency. But even if the memory starts at this higher frequency, in terms of heating it will not give a significant increase. So, we note once again that modern memory modules do not need radiators.

In general, radiators on modern memory modules do not so much serve as a heat sink, but rather allow manufacturers to simply expand their product range. If you painted the radiator black, you have a new line of memory aimed at overclockers; I installed pink radiators and got it new line memory for girls... In addition to the possibility of obtaining different lines of memory, heatsinks are also a sign that we are talking about high-speed memory modules that operate at an increased frequency, not specified in the JEDEC specification.

Let us recall that, according to the JEDEC standard, the maximum (effective) frequency of DDR3 memory is 1333 MHz with 9-9-9 timings and a supply voltage of 1.5 V. Naturally, any modern DDR3 memory will operate at a frequency of 1333 MHz at 1.5 V , however, all memory manufacturers also produce higher-speed modules (DDR3-1600/1866/2133/2400/2600), guaranteeing their stable operation in such overclocking mode. Memory operation at higher frequencies can be implemented either through an XMP profile, which specifies the frequency, supply voltage and timings, or by setting all of the listed parameters in manual mode(If Board BIOS does not support working with XMP profiles). However, do not forget that the ability of memory to operate at a higher speed than provided by the JEDEC specification depends not only on the module, but also on the memory controller integrated into the processor. For new Intel Core processors fourth generation(code name Haswell) memory controller officially only supports DDR3-1600 memory. Naturally, it is capable of supporting faster memory, but without any guarantees (it depends on your luck). As practice shows, most Haswell processors can support DDR3-1866/2133/2400/2600 memory without any problems.

Increasing the memory frequency, as a rule, requires changing other parameters - timings, supply voltage of the memory modules themselves, and supply voltage of the memory controller. The memory supply voltage, of course, does not affect system performance in any way, but increasing timings while simultaneously increasing the clock frequency can lead to DDR3-2133 memory with lower timings being more productive than DDR3-2400 memory with higher timings. Therefore, it is not always worth pursuing higher clock frequencies.

As for the influence of memory speed characteristics on the performance of the system as a whole, everything is very ambiguous. In general, user applications that would receive tangible The performance gain (speed of task execution) from increasing the memory frequency simply does not exist. That is, the fact that you double the memory frequency does not mean that there will be applications in which the speed of task execution will also double. In some applications, such an increase in clock frequency will not affect the speed at all, while in others the increase in speed will be very modest. In the processor, an increase in the clock frequency in many (but also not all) applications leads to an adequate increase in the speed of task execution, but with memory everything is a little different. However, we have already talked about this more than once. Let us make a reservation that such reasoning is valid provided that the memory operates in [at least] dual-channel mode, but in modern systems this condition is almost always met. And even single-channel memory (such options can be found in some laptops) will not provide double acceleration when the operating frequency is doubled. On the other hand, even if in some applications the performance gain from using faster memory is 5-7%, then why not? Especially when you consider that the cost difference between regular (DDR3-1333) and high-speed memory of the same volume is not so great.

Next, we will look at several dual-channel sets of modern high-speed DDR3 memory with a total capacity of 16 GB. These are sets of two or four memory models: if the set consists of four modules, it was installed in the test system with two modules per channel, and in the case of two modules - one module per channel. So, let's start with a more detailed acquaintance with the participants of our testing.

Kingston HyperX Predator KHX24C11T2K2/8X

Memory Kingston HyperX Predator KHX24C11T2K2/8X belongs to Kingston's HyperX Predator series overclocker gaming memory. Please read the following warning to users regarding the memory of this series: “Users may experience severe motion sickness and/or complete disorientation due to the extremely high operating speeds achieved with HyperX Predator modules. They are not intended for children, weak-willed people, people who are in no hurry, and for all those who can be content with little. The memory modules feature speeds up to 2666 MHz, a new heatsink for improved heat dissipation, support Intel XMP, are compatible with all major motherboard manufacturers, and feature legendary Kingston reliability. We would even recommend using a helmet."

This, of course, is a joke, but it clearly characterizes the audience these memory modules are aimed at.

HyperX Predator KHX24C11T2K2/8X memory is a set of two DDR3-2400 modules with a total capacity of 8 GB. Let’s immediately make a reservation that we used two sets of HyperX Predator KHX24C11T2K2/8X memory so that the total volume was 16 GB.

These memory modules are labeled KHX24C11T2K2/8X. Let us remind you that the following markings are used for Kingston HyperX memory modules. The first three letters - KHX - indicate that this is Kingston HyperX memory. The next two digits determine the memory clock speed. In our case it is 24, which corresponds to a clock frequency of 2400 MHz. Next, the CAS Latency value is set. Here C11 indicates that the CAS Latency value is 11 clock cycles. The next two characters (in our case T2) determine the type of memory within the Kingston HyperX series. The following indicates the number of memory modules included. So, K2 corresponds to two memory modules. The slash indicates the total amount of memory for the kit in gigabytes, and the presence of the letter X indicates compatibility of the memory with Intel XMP profiles (eXtreme Memory Profiles).

Thus, the marking KHX24C11T2K2/8X means that we are talking about a set of two DDR3 Kingston HyperX Predator memory modules with a clock frequency of 2400 MHz and a CAS Latency value of 11 clocks. The total memory capacity is 8 GB, in addition, the memory is compatible with Intel XMP profiles.

According to the specification, KHX24C11T2K2/8X memory modules support operation at a frequency of 1333 MHz with a supply voltage of 1.5 V and 9-9-9 timings (JEDEC specification), as well as two XMP profiles. The first profile corresponds to a clock frequency of 2400 MHz, and the second to a frequency of 2133 MHz. For the first XMP profile, the supply voltage is 1.65 V, and the timings are 11-13-13. For the second XMP profile, the supply voltage is 1.60 V, and the timings are 11-12-11.

It remains to add that the KHX24C11T2K2/8X memory modules have proprietary heatsinks for effective heat dissipation, and the height of the memory module with the heatsink is 53.9 mm, and its thickness is 7.24 mm.

On our test bench (see below), the Kingston HyperX Predator DDR3-2400 KHX24C11T2K2/8X memory started up without problems when using the XMP profile at 2400 MHz (timings 11-13-13). The frequency of 2600 MHz, with constant timings, turned out to be too much for the Kingston HyperX Predator DDR3-2400 KHX24C11T2K2/8X memory modules. However, they are not required to operate at such a frequency.

The following are the test results of a set of Kingston HyperX Predator DDR3-2400 KHX24C11T2K2/8X memory modules at a frequency of 1333 MHz (9-9-9-24) and 2400 MHz (11-13-13-30) in the AIDA64 program. Let us remind you once again that during testing we used two sets of Kingston HyperX Predator DDR3-2400 KHX24C11T2K2/8X memory.

Kingston HyperX Beast KHX21C11T3K2/16X

Memory Kingston HyperX Beast KHX21C11T3K2/16X belongs to the overclocking gaming memory of the Kingston series.

Distinctive feature memory modules of this series is that they use black printed circuit boards and a black aluminum radiator.

The manufacturer’s website notes that this design was made at the request of HyperX fans “to aggressively improve any enthusiast systems.” It’s not very clear what is meant (apparently, these are translation features), but “at the request of HyperX forfeits” - this is just like in the USSR, when prices were raised at the request of workers.

Again, according to the manufacturer’s website, HyperX Beast series memory modules are designed to work with third-generation Intel Core i5 and i7 processors and AMD processors.

Actually, there is only one comment here - this information is already outdated, and memory modules of this series are perfectly compatible with fourth-generation Intel Core processors.

We also add that HyperX Beast series memory modules are available in dual-channel and quad-channel kits with capacities from 8 to 64 GB and frequencies up to 2400 MHz. Modules in this series are provided with a lifetime warranty.

Kingston HyperX Beast KHX21C11T3K2/16X is a dual-channel set of two memory modules with a total capacity of 16 GB (2 × 8 GB). As follows from the KHX21C11T3K2/16X markings, the modules of this memory can operate at a clock frequency of 2133 MHz, and the CAS Latency value is 11 clock cycles.

According to, Kingston HyperX Beast KHX21C11T3K2/16X memory modules support operation at a frequency of 1333 MHz with a supply voltage of 1.5 V and 9-9-9 timings (JEDEC specification), as well as two XMP profiles. The first profile corresponds to a clock frequency of 2133 MHz, and the second to a frequency of 1600 MHz. For the first XMP profile, the supply voltage is 1.60 V, and the timings are 11-12-11. For the second XMP profile, the supply voltage is 1.5 V, and the timings are 9-9-9.

On our test bench, the Kingston HyperX Beast KHX21C11T3K2/16X memory started up without problems when using the XMP profile at 2133 MHz (timings 11-12-11-30).

In addition, as it turned out, the Kingston HyperX Beast KHX21C11T3K2/16X memory kit works without problems at a frequency of 2400 MHz, and at the same timings as at a frequency of 2133 MHz.

Geil Evo Veloce Frost White GEW316GB2400C11ADC

The Geil Evo Veloce Frost White GEW316GB2400C11ADC dual-channel memory kit belongs to the series announced by the company in 2012. Memory kits in this series are equipped with Maximum Thermal Conduction & Dissipation cooling radiators in red or white. Memory modules with white heatsinks are called Frost White, and those with red heatsinks are called Hot-rod Red.

In general, it must be said that Geil has a huge number of different series of DDR3 memory in its assortment, and each series has several variants of memory modules. Why such a huge range of products is needed is not very clear. After all, it is obvious that if you discard all the marketing “nonsense”, it turns out that the memory modules hiding behind heatsinks of different colors and belonging to different series are essentially the same thing.

For example, dual-channel DDR3-2400 memory kits belonging to the Geil Evo Veloce Frost White, Geil Evo Veloce Hot-rod Red and Evo Leggera series differ, in fact, only in the color of the radiator and marketing positioning. Each of these series has sets of memory modules with the same timings and equal volume. And, most likely, the memory chips themselves in these modules are the same. However, let's return to considering the dual-channel set of memory modules Geil Evo Veloce Frost White GEW316GB2400C11ADC.

So, we are talking about a set of two DDR3-2400 memory modules with a total capacity of 16 GB (2 × 8 GB). The memory modules are equipped with white radiators, that is, they belong to the Frost White series. In general, it should be noted that the memory radiators, although they have their own brand name, do not look impressive, let’s say. The thickness of the plates from which the radiator is made is only 1 mm. The height of the memory module with heatsink is 47 mm, and the thickness is 16.8 mm.

According to the information, at a frequency of 2400 MHz, Geil Evo Veloce Frost White GEW316GB2400C11ADC memory modules can operate with timings of 11-12-12-30 with a supply voltage of 1.65 V.

Moreover, this mode of operation of memory modules is ensured when the Intel XMP profile is activated and is guaranteed by the manufacturer only on motherboards with Intel X79 and Intel Z77 chipsets, as indicated by the corresponding sticker on the packaging of memory modules.

Guaranteed compatibility with Intel X79 and Intel Z77 chipsets is explained by the fact that motherboards based on these chipsets support Intel XMP memory profiles. Naturally, today support for XMP profiles is provided by a large number of chipsets (in particular, Intel 8-series chipsets), so you can guarantee the functionality of this memory with the XMP profile on boards with the Intel Z87 chipset.

However, we would like to remind you that Intel XMP profiles are not supported on boards with AMD chipsets, and to run this memory in overclocked mode, you must set the frequency, voltage, and timings manually.

Note that the series of dual-channel DDR3-2400 Geil Evo Veloce Frost White memory also includes 8 and 16 GB memory kits with timings 9-11-10-28 (GEW38GB2400C9DC/GEW316GB2400C9DC), 10-11-11-30 (GEW38GB2400C10DC/GEW316GB2400C1 0DC) , 10-12-12-30 (GEW38GB2400C10ADC/GEW316GB2400C10ADC), 11-11-11-30 (GEW38GB2400C11DC/GEW316GB2400C11DC). So the GEW316GB2400C11ADC memory kit has the least aggressive timings in the DDR3-2400 Geil Evo Veloce Frost White line, that is, it is the youngest model in the series.

On our test bench, the Geil Evo Veloce Frost White GEW316GB2400C11ADC memory started up without problems when using the XMP profile at 2400 MHz.

A frequency of 2600 MHz, with constant timings, turned out to be beyond the capabilities of these memory modules. However, increasing the main timings by one step makes it easy to run this memory at 2600 MHz.

Corsair Vengeance CMZ16GX3M2A1866C9

Corsair Vengeance CMZ16GX3M2A1866C9 is a dual-channel DDR3-1866 memory module kit with a total capacity of 16 GB (2 × 8 GB).

This memory kit also belongs to the Corsair Vengeance series, aimed at overclockers.

In terms of the design of aluminum radiators, the modules of the dual-channel Corsair Vengeance CMZ16GX3M2A1866C9 memory kit are practically no different from the modules of the four-channel Corsair Vengeance CMZ16GX3M4X2133C11R memory kit. The only difference is the color of the radiator. In this case it is black.

According to the information, Corsair Vengeance CMZ16GX3M2A1866C9 memory modules support a frequency of 1866 MHz with timings of 9-10-9-27 and a supply voltage of 1.5 V.

Naturally, this operating mode corresponds to the XMP profile. Well, in standard operating mode the memory operates in DDR-1333 mode with timings of 9-9-9-24.

On our test bench, the Corsair Vengeance CMZ16GX3M2A1866C9 memory started up without problems when using the XMP profile at 1866 MHz.

However, as it turned out, the frequency of 1866 MHz is not the limit for this memory and it can be easily overclocked to a frequency of 2000 MHz at the same timings as for the frequency of 1866 MHz.

Corsair Vengeance CMZ16GX3M4X2133C11R

Corsair Vengeance CMZ16GX3M4X2133C11R is a set of four DDR3-2133 memory modules with a total capacity of 16 GB (4 × 4 GB).

This memory kit belongs to the Corsair Vengeance series, aimed at overclockers. According to , the Corsair Vengeance series memory modules use memory chips that are specifically selected for high performance potential.

The modules of this kit are equipped with heatsinks that not only provide heat dissipation, but also serve as an element of aggressive design that is perfect for gaming computers. The heatsink on the memory module consists of two aluminum plates (one plate on each side of the module) 1 mm thick, which are painted burgundy and have stickers indicating the series and characteristics of the module. The height of the memory modules, including the radiator, is 53 mm, and the width is 17 mm.

Note that the Corsair Vengeance series includes one-, two-, three- and four-channel memory kits with capacities from 4 to 16 GB, which differ in timings, color, and even the shape of the radiator.

The Corsair Vengeance CMZ16GX3M4X2133C11R kit, as already noted, consists of four memory modules with a capacity of 4 GB each. Accordingly, this kit can be used in dual-channel or quad-channel memory modes.

According to the information, Corsair Vengeance CMZ16GX3M4X2133C11R memory modules support a frequency of 2133 MHz with timings of 11-11-11-27 and a supply voltage of 1.5 V.

Naturally, this operating mode corresponds to the XMP profile. Well, in standard operating mode the memory operates in DDR3-1333 mode with timings of 9-9-9-24.

However, according to the results of a diagnostic test in the AIDA64 utility, it turned out that the XMP profile of this memory contains slightly different timings: not 11-11-11-27, but 11-11-11-30. The difference, of course, is not significant, but it is there.

On our test bench, the Corsair Vengeance CMZ16GX3M4X2133C11R memory started up without problems when using the XMP profile at 2133 MHz with timings 11-11-11-30.

Moreover, it turned out that with constant timings this memory runs without problems at a frequency of 2200 MHz.

Corsair Vengeance Pro CMY16GX3M4A2400C10R

Corsair Vengeance Pro CMY16GX3M4A2400C10R is a dual-channel DDR3-2400 memory module kit with a total capacity of 16 GB (2 × 8 GB).

This memory kit belongs to the Corsair Vengeance Pro series, aimed at overclockers. It is noted that the Corsair Vengeance Pro series memory kits are specially designed for Intel processors Core third and fourth generations.

Memory modules in this series use aluminum radiators of various colors. The height of the memory modules, including the radiator, is 46 mm, and the width is 17.5 mm.

The Corsair Vengeance Pro series includes kits consisting of two or four memory modules with a total capacity of 8 to 32 GB and a frequency of 1600 to 2400 MHz.

The Corsair Vengeance Pro CMY16GX3M4A2400C10R memory kit, as already noted, consists of two memory modules with a capacity of 8 GB each. These memory modules are equipped with black aluminum radiators with a decorative burgundy insert. On the radiator, on one side there is a sticker with information about the memory series (Vengeance Pro), and on the other side there is a sticker with information about the characteristics of the memory module (frequency, timings, supply voltage).

According to the information, Corsair Vengeance Pro CMY16GX3M4A2400C10R memory modules support a frequency of 2400 MHz with timings of 10-12-12-31 and a supply voltage of 1.65 V.

Naturally, this operating mode corresponds to the XMP profile. Well, in standard operating mode the memory operates in DDR-1333 mode with timings of 9-9-9-24.

As it turned out during testing, everything turned out to be quite difficult with the Corsair Vengeance Pro CMY16GX3M4A2400C10R modules.

The fact is that the declared XMP profile for 2400 MHz is missing. Instead, there is an XMP profile at a frequency of 1866 MHz with timings of 9-10-9-27. But even when this profile is activated in the BIOS, the memory operates at a frequency of 1800 MHz, and not 1866 MHz.

However, if you set the memory frequency, supply voltage and timings in the BIOS manually (2400 MHz, 1.65 V, 10-12-12-31), then the memory will work as it should.

Testing

So, in total, six memory sets took part in our testing, each of which was tested in two operating modes:

• Corsair Vengeance Pro
  • Corsair CMY16GX3M2A2400C10R @1800 MHz 9-10-9-27
  • Corsair CMY16GX3M2A2400C10R @2400 MHz 10-12-12-31
• Corsair Vengeance (DDR3-1866)
  • Corsair CMZ16GX3M2A1866C9 @1866 MHz 9-10-9-27
  • Corsair CMZ16GX3M2A1866C9 @2000 MHz 9-10-9-27
• Corsair Vengeance (DDR3-2133)
  • Corsair CMZ16GX3M4X2133C11R @2133 MHz 11-11-11-30
  • Corsair CMZ16GX3M4X2133C11R @2200 MHz 11-11-11-30
• Geil Evo Veloce
  • Geil GEW316GB2400C11ADC @2400 MHz 11-12-12-30
  • Geil GEW316GB2400C11ADC @2600 MHz 12-13-13-32
• Kingston HyperX Beast
  • Kingston KHX21C11T3K2/16X @2133 MHz 11-12-11-30
  • Kingston KHX21C11T3K2/16X @2400 MHz 11-12-11-30
• Kingston HyperX Predator
  • Kingston KHX24C11T2K2/8X @1333 MHz 9-9-9-24
  • Kingston KHX24C11T2K2/8X @2400 MHz 11-13-13-30

For testing we used a stand with the following configuration:

• processor - Intel Core i7-4770K;
• motherboard - ASRock Z87 OC Formula;
• chipset - Intel Z87;
• drive - Intel SSD 520 Series (240 GB);
• operating system - Windows 8 (64-bit).

Perhaps the most non-trivial task when testing memory is to find those applications and tasks in which you can really see the difference in performance for memory with different frequencies.

Naturally, we used the synthetic AIDA64 test, which allows us to determine the speed of reading, writing and copying data, as well as memory latency. The results of this synthetic test are shown below.

As a basis, we took Kingston HyperX KHX24C11T2K2/8X memory in 1333 MHz mode with timings 9-9-9-24, which complies with the JEDEC specification.

As you can see, here you can quite see the difference between DDR3-1333 memory and memory with a higher clock speed.

However, this test is synthetic. Now let's see what happens in tests based on real applications.

As we have already said, not all applications are “sensitive” to memory speed - more precisely, the DDR3-1333 bandwidth is sufficient for most applications, and further increase in memory frequency becomes pointless. However, we were able to find a number of test tasks based on real applications in which we can record the difference in system performance when using memory modules with different frequencies.

As a result, we selected the following set of applications for testing:

• MediaCoder x64 0.8.25.5560;
• Adobe Premiere Pro CC;
• Adobe After Effects CC;
• Adobe Photoshop CC;
• Adobe Audition CC;
• Photodex ProShow Gold 5.0.3276;
• WinRAR 5.0.

In the application MediaCoder x64 0.8.25.5560 The 3:35 HD video is transcoded into another format with a lower resolution. The source video is recorded in H.264 format and has the following characteristics:

• size - 1.05 GB;
• container - MKV;
• resolution - 1920×1080;
• frame rate - 25 fps;
• video bitrate - 42.1 Mbit/s;
• audio bitrate - 128 Kbps;
• number of audio channels - 2;
• sampling frequency - 44.1 kHz.

The parameters of the resulting video file are as follows:

• size - 258 MB;
• container - MP4;
• video codec - MPEG4 AVC (H.264);
• resolution - 1280×720;
• frame rate - 29.97 fps;
• video bitrate - 10000 Kbps;
• audio codec - AAC;
• audio bitrate - 128 Kbps;
• number of channels - 2;

The result of this test is the conversion time.

Adobe Premiere Pro CC a video is created from ten video clips with a total volume of 1.48 GB. Video clips (MOV container) were shot with a Canon EOS Mark II 5D camera with a resolution of 1920x1080 and a frame rate of 25 fps. Transition effects are created between all video clips, after which the workspace is rendered and the video file with the preset is exported Apple iPad 2, 3, 4, Mini; iPhone 4S, 5; Apple TV3 - 1080p 25. The finished film is 4:25 long and 163 MB in size.

• container - MP4;
• resolution - 1920×1080;
• video codec - MPEG4 AVC (H.264);
• video bitrate - 5 Mbit/s;
• frame rate - 25 fps;
• audio codec - AAC;
• audio bitrate - 160 Kbps;

The result of this test is the total time for rendering and exporting the movie.

In a test using the application Adobe After Effects CC a 30-second video (MOV container) of 164 MB in size, shot with a Canon EOS Mark II 5D camera with a resolution of 1920x1080 and a frame rate of 25 fps, is processed, followed by rendering without compression (AVI container) using the built-in renderer.

Processing consists of adjusting the white balance, applying a Cartoon filter and applying 3D titles with various effects (explosion, blur, etc.)

The output file parameters are as follows:

• resolution - 1920×1080;
• video codec - no (uncompressed video);
• container - AVI;
• video bitrate - 1492 Mbit/s;
• frame rate - 30 fps.
• audio codec - PCM;
• audio bitrate - 1536 Kbps;
• number of channels - 2 (stereo);
• sampling frequency - 48 kHz.

The output video file size is 5.21 GB. The result of this test is the video rendering time.

Photodeх ProShow Gold 5.0.3276 determines the speed of creating an HD video (slideshow) with a resolution of 1920x1080 (MPEG-2 format, 59.94 fps) from 24 digital photographs taken with an EOS Canon Mark II 5D camera and converted to TIFF format. Each photo is 60.1 MB in size. In addition, the film is accompanied by music. The movie itself is created using the Wizard of the Photodeх ProShow application. Various transition effects are applied between individual slides, and some of the slides are animated.

The test result is the total time to create a slideshow project, including the time to load photos and music and apply special effects, as well as the time to export the project to a movie.

In a test using the application Adobe Photoshop CC Batch processing of 24 photographs taken with an EOS Canon Mark II 5D camera is carried out in RAW format (the size of each photograph is 25 MB). With each photo that opens in 8-bit format, the following actions are performed sequentially:

• color depth changes from 8 to 16 bits per channel;
• the Smart Sharpen adaptive sharpening filter is applied;
• a filter to eliminate hand shake when shooting Shake Reduction is applied;
• a Reduce Noise noise reduction filter is applied;
• the lens distortion correction filter Lens Correction is applied;
• color depth changes from 16 to 8 bits per channel;
• the photo is saved in TIFF format.

The result of this test is the batch processing time for all photos.

In a test using the application Adobe Audition CC six-channel (5.1) audio file in FLAC format(lossless compressed) is initially processed and then converted to MP3 format. Processing the source file involves applying an Adaptive Noise Reduction filter to it. The test result is the total processing and conversion time of the audio file. The original test audio file is 1.65 GB in size. The parameters of the resulting MP3 file are as follows:

• bitrate - 128 Kbps;
• sampling frequency - 48 kHz.

In a test using an application application WinRAR 5.0 (64-bit version) archives an album of 24 digital photographs in TIFF format (the size of each photo is 60.1 MB). The WinRAR 5.0 archiver uses the RAR5 format for data compression, the Best compression method (maximum compression) and a dictionary size of 32 MB.

The test result is the archiving time.

When testing memory, all tests were run three times, and the computer was rebooted between each run.

Test results

Well, now let's turn to the test results. As before, we used Kingston KHX24C11T2K2/8X memory in 1333 MHz mode with timings of 9-9-9-24 as a basis.

So, let's start with a video transcoding test using the MediaCoder x64 0.8.25.5560 application. As we can see, this task is not very sensitive to memory speed. The worst result (112.4 s for DDR3-1333 memory) differs from the best (109.1 s for DDR3-2400 memory) by only 3%. Well, there is practically no difference in test execution speed between DDR3-1866 and DDR3-2400 memory.

Adobe Premiere Pro CC is a little more sensitive to memory speed: in our test, the difference between the worst and best results is 6.5%. Well, that's already something.

But in a test based on the Adobe After Effects CC application, the difference between the worst and best results again does not exceed 3%.

Photodex ProShow Gold is a little more sensitive to memory speed, and in our test there was a 6% difference between worst and best results.

Adobe Photoshop CC turned out to be even more sensitive to memory speed. Here we finally saw something that could really be called a difference: 11% between the best and worst results. However, the worst here, of course, is the DDR3-1333 memory indicator, and if we take DDR3-1800 as the base indicator, then the difference, alas, is reduced to 5%.

We present the test results based on the Adobe Audition CC application from our methodology not so much to demonstrate the advantages of high-speed memory, but to demonstrate the absence of these advantages in many, many applications. In our test based on this app, the difference between the worst and best results is only 2%, meaning there is virtually no difference at all.

But the data compression test based on the WinRAR 5.0 application is very sensitive to memory speed. The Photoshop record has not been achieved here, but the difference between the worst and best results is quite a respectable 9.5%, which is very good.

conclusions

Actually, the conclusions that can be drawn from our testing are quite predictable. There is no particular point in high-speed memory today, and DDR3-1333 memory is quite sufficient for most user applications. The maximum performance increase that can be obtained by using high-speed DDR3-2400 or DDR3-2600 memory instead of standard DDR3-1333 memory can barely exceed 10%, and tasks that allow you to reveal such an advantage of high-speed memory still need to be looked for.

As for the various oddly shaped heatsinks on high-speed memory modules, which, according to marketers, make it possible to increase heat dissipation efficiency, this is nothing more than a fiction. Modern memory with a frequency of 2400 and even 2600 MHz with a supply voltage increased to 1.65 V, radiators are not needed at all, which was confirmed by the numbers in the preface to this review.

Now about the cost. On average, a set of high-speed DDR3-2400 memory with a capacity of 16 GB costs about 7-8 thousand rubles (you can find more expensive ones - it all depends on the brand, model and the conscience of the seller). A set of DDR3-1333 memory of the same volume (and of the same brand) will cost approximately 5-6 thousand rubles.

If we are talking about a top-end high-performance PC based on a processor, for example, an Intel Core i7-4770K and a motherboard based on the Intel Z87 chipset, then even a few percent of additional performance due to the use of high-speed memory may not be superfluous, and then there is no point in saving on memory. Moreover, the difference in cost between high-speed memory and standard memory is very small (compared to the cost of a similar computer as a whole, of course). If we are talking about an ordinary inexpensive or office PC, then high-speed memory makes no sense at all.

As for the question of choosing a specific manufacturer (Kingston, Corsair, Geil, Samsung, etc.), we remind you once again that all memory modules use chips manufactured by Samsung, Micron and Hynix. And by and large, it is absolutely unimportant who exactly is the manufacturer of the memory module. Perhaps this is the last thing you should pay attention to.

A mandatory component that will be required when assembling any computer device- RAM. If you carefully study the assortment of stores, you will notice several clear trends. Firstly, with regard to desktops, it is quite possible to say that DDR3-1333 strips are already disappearing from the scene, and the most “popular” memory clock frequency has become 1600 MHz (PC3-12800). It is among the PC3-12800 kits that there are now the largest number of offers at different prices. Secondly, now the average computer is equipped not with 4 GB of RAM, but with 8 GB. The second factor is caused not so much by increased demands software, how with a common desire to put on your computer more memory. At the same time, in gaming and professional computers, RAM of both 16 GB and 32 GB is increasingly common. But a kit of two 4 GB modules will remain a “classic” for a home PC for a long time, and constant demand contributes to lower prices.

Therefore, we decided to test several kits, not limiting ourselves to a frequency of 1600 MHz, but, on the contrary, to take the fastest kits with memory clock frequencies of 2133 MHz and 2400 MHz that are relevant for modern platforms.

The main requirements for the kits will be operability and high performance when setting the parameters declared by the manufacturer (timing values ​​recorded in the SPD). We will also appreciate the ease of installation (which can be extremely difficult due to high radiators), appearance and quality of packaging. We will also conduct a series of tests with parameters that are too high relative to the nominal to determine the suitability of the chips for overclocking and the feasibility of this undertaking as such.

In general, are these megahertz needed?

This question was raised by the noticeable difference in the cost of memory with “budget” and “overclocker” clock frequencies. Today, a kit of DDR3 2 x 4 GB with a frequency of 1600 MHz retails for 1,300 rubles, high-speed memory DDR3-2133 is already 1,900 rubles. and higher. So you’ll think about what’s better, give preference quick kit smaller volume (it’s cheaper) or pay the required amount and take four 4 GB sticks? You can argue and search for the truth for a long time, but one thing is clear: 16 GB of RAM will always cost significantly more than 8 GB, and if you do not professionally engage in cryptography, data archiving and video editing, most of the RAM will not be used. Therefore, it is most reasonable to opt for an 8-gigabyte set, the modules in which, if not selected to work together, are at least assembled from chips from the same batch, which means that there is at least a little less chance of encountering incompatibility. In addition, the packaging of branded kits is stronger than an antistatic bag with OEM memory, and the slats have a higher chance of surviving during transportation. So, let's see what sets came to our testlab.

Rely on XMP, but don't make a mistake yourself

A little warning. Even if you like some memory, you read a lot of tests and positive reviews on it, don’t rush to the store. One important nuance must be taken into account. You probably know that the lion's share of sudden computer "whims" is due to memory failure? Manufacturers of components, in particular motherboards, are well aware of this, therefore, when preparing a product for entering the market, they prepare a compatibility sheet for a specific motherboard model with various components, mainly processors and RAM. Moreover, if support for more modern CPUs appears in new BIOS revisions, then the expansion of the range of compatible memory occurs much less frequently.

When assembling a computer that has high reliability requirements, be it a mini-server or an HTPC with a cramped case and a weak power supply, you should choose any memory model from the QVL (Quality Vendor List), but if the main goal is overclocking, you can take a risk, installing memory that the vendor did not have time to test and approve, but in this case you will have to adjust the timings and supply voltage of the modules according to their specifications, without relying on SPD and XMP. And if it is difficult to start the system or blue screens appear, do not forget to go through the full Memtest test cycle.

DDR3 memory tests | Goodram Pro DDR3-2133 2 x 2 GB (GP2133D364L10/4GDC)

This 2 x 2 GB DDR kit is manufactured in Poland by Wilk Elektronik. The memory strips are hidden in individual transparent blister packaging, and the required number of blisters for double- or triple-kits is secured with paper tape, on which the name of the kit, its article number and the timings necessary for operation at a frequency of 2133 MHz are printed (10-10-10-30) . There is no information about the required supply voltage, there is no information about “proper nutrition” on the sticker on the radiators. There are no specifications on the manufacturer's website, but there is a piece of paper inside the package reminding you that you need to set the correct operating frequency in the BIOS.

This is not difficult to do because the XMP profile system is supported, but in fact, only one set of XMP parameters for the frequency of 2133 MHz, given above, is “hardwired” into the EEPROM. This makes it possible, without going into settings, to force the memory to work at the optimal frequency by changing just one line in the BIOS, of course, provided that the platform is based on an Intel chipset. Is the system working with memory? Goodram Pro on the parameters chosen by the manufacturer and whether it is suitable for overclocking platforms, we will find out below.

To protect against overheating (and, partly, against mechanical damage) modules Goodram Pro DDR3 is protected by thin (1mm) aluminum plates, for some reason blue, despite the fact that orange is considered the corporate color. Symbolism Goodram Pro milled on one of the radiator halves, on the other there is a sticker with module parameters and a barcode. The bank of DDR3 chips is located on one side of the PCB; there are 8 of them. On the other side, instead of microcircuits, a thick gasket is glued on. Heat removal from the chips is organized through thin thermal tape, so removing metal plates without preliminary technological heating is not recommended - you can tear off the chips “with meat”, precedents are known. Although why remove them, from practical experience we can say that heating of the memory is insignificant and does not affect anything at home; and overclockers themselves know how to “expose” the chips and put, for example, a water block or a more efficient heat dissipator on them without thermal tape, directly.

Radiators are only two millimeters higher printed circuit board, therefore, a mechanical conflict between the slats and the “spreading” CPU heatsink is practically excluded. There is no need to talk about any heating of these radiators in standard modes; over the entire area of ​​aluminum, the temperature did not exceed 35°C, even during calculations in the Super PI 32M benchmark, one must assume that even in a closed case the heating of the chips is unlikely to reach any dangerous values.

It is necessary to add that these modules are not yet widely available, and the volume of the kit, 2 x 2 GB, is not enough to attract the attention of an enthusiast even for a moment. So we are waiting for new capacious and fast samples from Poland.

DDR3 memory tests | Apacer Armor Series DDR3-2133 2 x 4 GB (78.BAGGL.AFK0C)

RAM from this Taiwanese manufacturer is rarely found in Russian stores, but flash drives and card readers have been known for quite a long time. Armor Series is Apacer's top overclocking memory series, which includes DDR3 kits with clock frequencies of 1600 MHz, 1866 MHz, 2133 MHz, and it was the latter option that ended up in our testlab. Memory Apacer Armor Series comes in a beautiful printed packaging with a window, inside which is a plastic blister with a pair of modules. The color of radiators can be black, red, yellow, turquoise, you can choose it to your liking. The information on the label is extremely sparse; it is absolutely impossible to understand what supply voltage the memory chips are designed for, but if you look closely at the factory label glued to the strips, you can see the line 4GB UNB PC3-17000 CL11-11-11-30. That is, the nominal memory frequency should be 2133 MHz with worse timings than the Goodram product. Practical tests will show how much this fact will affect performance.

Similar to the Goodram product, cooling radiators do not have developed fins and are painted aluminum plates-plates glued to thermal tape on both sides of the printed circuit board. It’s even a pity to hide such beauty in a body. The thermal interface layer is very thin, noticeably thinner than that of Goodram.

The testlab had two sets of identical memory at its disposal, not immediately, but it was noticed that the heatsinks were poorly glued to the chips in all four samples. True, this did not affect the performance in any way, which only emphasized the decorative purpose of these plates.

In Apacer memory, the heatsinks barely extend beyond the upper dimension of the printed circuit board, so here too there will be no interference with a powerful (wide) cooler; the brackets are very compact. The total height is 32 mm, this value can be taken as a reference value, and “colleagues” can be compared with it.

DDR3 memory tests | Corsair Vengeance 8GB DDR3-2133 2 x 4 GB (CMZ8GX3M2X2133C9R)

Vengeance memory from the Corsair brand, famous among overclockers, attracts attention primarily with its elegant appearance, and the outer packaging is made as bright as possible. Photographic quality printing depicting a fragment of a printed circuit board, where there are a couple of RAM modules in the slots, bright red color everywhere possible, familiar Intel and AMD icons in plain sight. But the diversity and brightness did not come at the expense of information content; on the back side in the window you can see the strips themselves, on the tag of which the voltage (1.5 V) and operating frequency (2133 MHz) are indicated, and very encouraging delays 9-11-10-30 for this frequency. The CAS# Latency parameter (first value) sometimes has a stronger impact on performance than other parameters, so even without opening the kit, you can be sure that the chips were selected by the manufacturer to achieve stable operation at short latencies.

Inside the cardboard shell there are separate blisters for each module, thus, the requirements for reliable protection of products during transportation are fully met.

Having taken the planks out of the packaging, we again see that the manufacturer paid a lot of attention to the design. The chip heatsinks not only have an unusual, recognizable shape, but are also painted with bright cherry-colored metallic paint. The plump ridge of the radiator sticks out nicely, so when choosing Corsair Vengeance In your computer, you need to know exactly how much space the processor cooler “left” for you, or be prepared to install RAM in the slots furthest from the socket.

A visual demonstration of the height of Corsair Vengeance modules installed together with the Thermaltake Frio Extreme cooler. From left to right: Apacer Armor Series (32mm), Geil Evo Corsa (42mm), Corsair Vengeance (52mm). The first (from the processor) slot is not occupied.

DDR3 memory tests | ADATA XPG Xtreme Series DDR3 2133 2 x 4 GB (AX3U2133XC4G10-2X)

ADATA, like Apacer, has never been a major player in the RAM market, but the recent expansion of the range of SSDs and flash drives has borne fruit, and the company has decided to try its hand at the RAM market.

Unlike the standard packaging form (internal durable case and outer cardboard shell), ADATA memory sticks are packaged only in a blister. And due to the fact that the box is sealed in a circle, its integrity is immediately visible. The disadvantage of this solution is that cut packaging is difficult to keep neat. The parameters of the memory chips are not indicated on the packaging, but the timings, frequency and supply voltage can be found on the tags attached to the memory heatsinks, which are clearly visible through the transparent packaging.

Before us again are two “low-profile” modules, the radiators of which are thin metal plates attached with thermal tape. The height of the bar is 30 mm; most coolers will not interfere with placing this memory in the first slot. The recommended parameters in this RAM are alarming: the supply voltage is 1.65V - clearly higher than the “hospital average” value of 1.5 - 1.6 V, while the set of timings does not look optimal - 10-11-11-30. The first impression is that through selection from the batch, microcircuits of a lower performance class that were not capable of reaching higher frequencies were rejected, and suitable copies were used to complete the memory ADATA XPG Xtreme Series, and the voltage is raised up to achieve greater stability in non-standard modes for chips. If this is the case, then you shouldn’t really hope for further overclocking. But we will definitely try.

DDR3 memory tests | Geil Evo Corsa 2400MHz 2 x 4 GB (GOC38GB2400C11ADC)

Memory from Geil in today's test belongs to a higher speed class than previous participants. Geil produces memory chips independently. The product lines include both regular memory and overclocking memory with advanced characteristics. Widespread sales of DDR modules from this manufacturer have not been noticed in Russia, but they are well known to enthusiasts. Colleagues have repeatedly tried to draw the attention of readers to inexpensive memory, which sometimes showed very high results in tests, despite the low price.

The packaging of Evo Corsa is standard both for Geil devices themselves and for many other similar kits from other factories: internal plastic blister and cardboard outer lining. There are no complaints about the design of the pack, everything is modest and even tasteful, and the parameters (timings and operating frequency) are not hidden in the far corner, but are shown in a visible place in a white plate. Their double is clearly visible through the window in the package. By design and appearance memory Geil Evo Corsa very similar to Corsair Vengeance, a slightly different shape of the radiators, green PCB boards, but there are definitely similarities. The height of the slats is 47 mm, which is quite a lot, which means that conflicts with oversized cooling systems are again possible. It is stated that the memory is capable of running at 2400 MHz with timings of 11-12-12-30 at a supply voltage of 1.65 V. In this situation, the numbers look quite adequate, since the clock frequency is quite high, and the CAS# Latency value = 11 at 2400 MHz - Fine.

The BGA chip housings are coated with an innovative coating consisting of carbon and silicon, which dissipates excess heat.

We'll talk about its effectiveness later, and we'll also try to determine the temperature of the chips.

The blue packaging of the modules, the windows in which are made in the form of arrows, is both beautiful and informative. On the back side there is a detailed specification, indicating the permissible supply voltage - 1.5-1.8 V, and CAS# Latency timing values. And inside the cardboard packaging there is a hard plastic trough, in which the modules are held very tightly. You have to make significant efforts, bending the plastic and the modules themselves in order to get them out of captivity.

There is practically nothing to add to what was written above; here is a printed circuit board with 16 BGA chips, painted turquoise. It is the heat-dissipating coating that is of greatest interest. Under a strong 12x magnifying glass, the patented coating looks like a layer of baked enamel, the surface is very heterogeneous, lumpy, but at the same time smooth.

The characteristics declared by the manufacturer are promising; you can try both ways to increase performance: both short timings and an increased clock frequency (up to 2400 MHz). In any case, it will be very interesting to check the capabilities of “nanomemory”.

DDR3 memory tests | Test stand, methodology and software

The memory test took place on a bench; the list of components from which it was assembled is given in the table:

• CPU AMD FX-8350 (Vishera)
• Maternal ASUS board ROG Crosshair V Formula ( AMD chipset 990FX/SB950), BIOS version 1703
• Point of View GeForce GTX 580 graphics card
• power unit Cooler Master 1200 W
• Cooling Air cooler
• Thermaltake Frio Extreme
• Corsair Neutron GTX 240GB SSD
• operating room Windows system 7 x64 Ultimate

The AMD platform was chosen only due to the presence of an appropriately configured motherboard, which had previously shown itself to be absolutely stable, accurately withstanding the voltage and frequency of the tested components, at the same time, it has a huge number of adjustable parameters in the BIOS. AMD processors of the latest Vishera microarchitecture have significantly increased speed compared to their predecessors. It was decided to abandon overclocking the CPU altogether; the bus frequencies and multiplier did not change from test to test, but in a real situation it is better to overclock this processor; the performance increase is decent.

Information from the main window of the CPU-Z utility. The processor frequency was set automatically in the BIOS, so there were still some upward deviations from round numbers. This is a feature of the motherboard sample, or rather, this is how ASUS configured it

Having chosen the AMD platform, I had to abandon the Intel XMP profile system, trusting Jedec standards and profile settings in SPD. And for some kits they were so strange that it was necessary to adjust the basic parameters, since they not only did not coincide with the passport ones, but also, in most cases, were not optimal.

The set of tests included purely synthetic benchmarks: “graphical” 3D Mark 11 (with “Performance” settings) and “platform” PCMark 7 (scores in the “Creativity” and “Productivity” tests were taken into account). The Creativity tests evaluate the performance of the main components when processing photo and video materials, and the Productivity tests evaluate the speed when processing Internet tasks and office packages. Having received data on the impact of memory settings on the results obtained in these benchmarks, it will be possible to indirectly judge the impact of memory performance on the overall performance of the PC.

It seemed interesting to include SiSoftware Sandra Personal 2013.01.19.23 in the tests and use it to evaluate the performance of the processor-memory connection in cryptographic tasks, fortunately there is such a module in the program. On the modern Internet, cryptography is used very often: content encryption modules, secure Web pages, Internet banking, systems remote access. In addition, this test responds very well to changes in memory frequencies.

And latency and throughput will clearly be shown by the traditional AIDA Cache & Memory Benchmark test. Of the real applications, the most sensitive to memory parameters are still archivers, including their built-in benchmarks, so let’s take two popular packages: WinRAR 4.20 and 7-Zip 9.20, 64-bit versions. I had to take a couple of software at once, since 7-Zip performs multi-threaded calculations more accurately than WinRAR, and the estimation accuracy is higher, since the compression algorithms are slightly different.

As with any stress test of components, you may encounter instability, and it is unknown how and when it will manifest itself. In order not to waste time collecting the main results, first we ran “heavy” tests, which, if the timings were set incorrectly, are guaranteed to lead to a freeze or BSoD. This is, first of all, 3D Mark 11, especially its subsections using calculations physical models, "calculator" Super PI / mod 1.5 XS 32M and one of the archivers. If all these tests passed without any hiccups, as a rule, there were no further problems. The most important thing was not to get some “pretty” number showing productivity AMD platforms, but to compare the performance of memory strips with each other, providing them with the most similar modes with the same set of tests. It is clear that the speed of the memory controller built into an Intel CPU is higher, but in percentage terms the difference between the results of different memory sets in the same tests will be almost the same on both platforms.

DDR3 memory tests | Factory settings: a lot of strange things

Almost every user who has purchased a set of RAM is sure that installing dividers and multipliers on Auto is not only what is recommended by the manufacturer, but also eliminates the hassle of lengthy selection of parameters, so it is not surprising that this scenario is most often played out. Let's see what happens in this case.

Goodram Pro

Memory from Goodram has proven to be a great reinsurer. On Auto, the frequency was set to 1333 MHz with a latency formula of 8-8-8-22, but this applies to AMD platforms, since the XMP profile fully corresponds to the information on the packaging: 1066 MHz and timings 10-10-10-30. The tRC parameter of 40 is too high, although it is not the most important, but it could be reduced to at least 36.

Goodram Pro default memory timing table

If for some reason you choose a frequency of 1333 MHz, for example, the old chipset will not handle more, then it is advisable to try to lower the timings as much as possible. It turned out that the Polish kit easily starts at 1333 MHz with delays of 7-7-7-22, having passed all stability tests, but even after the final “polishing” of the minor timings, it is unlikely that it will be possible to achieve high performance of the memory subsystem, and we will see this in comparative diagrams.

Minimum timings of Goodram Pro memory at which it is still stable

The situation with frequency overclocking does not look so rosy. The computer starts perfectly at 2400 MHz with the delays set to 11-11-11-28 CR2, but categorically refuses to pass the “physics test” in 3D Mark 11, and also freezes after 15-20 minutes of running the built-in 7-Zip benchmark. There is no point in increasing the first value of CAS# Latency to “12”, yes, stability may appear, but in terms of speed it will be the slowest kit.

At rated frequency >Goodram Pro worked as expected and even allowed us to slightly improve performance by reducing delays. The best in all tests was the combination of a clock frequency of 2133 MHz with timings of 9-10-10-26.

Excellent stability, fairly high read/write speeds, low latency at 2133 MHz are achieved by carefully configuring memory parameters in the BIOS. The factory settings are too rough and need to be adjusted.

The operation of the Polish kit at a frequency of 1600 MHz also did not raise any questions, but here it turned out to be possible to “twist the knobs a little”; the CAS# Latency parameter should be set to 8 instead of 9. This gives a sharp increase in throughput and reduces latency.

Apacer Armor Series

As mentioned above, the set of settings for the frequency of 2133 MHz was chosen by the manufacturer in vain. The formula 11-11-11-30 CR2 is clearly not for winning, but it is precisely what is “sewn in” in the form of an XMP profile. And the recommended voltage of 1.65 V is a bit high.

Please note that at 1600 MHz the timings will be almost the same as at 2133 MHz. This will lead to a noticeable decrease in speed in processor-dependent applications

It would be strange not to try to improve the situation, but we were not very successful in this. It seems like a successful start of the kit at 2400 MHz with the formula 11-12-11-30 CR2, even passing the physics test in 3D Mark 11, but the repetition fatal error The archivers say that we have climbed too high.

As a result, the results collected at frequencies of 1600 MHz and 2133 MHz were taken into account, and in both cases it was possible to slightly reduce the timing values, which could not but improve the results.

The difference at a frequency of 2133 MHz is immediately visible, the upper result was obtained at nominal settings, the lower – when setting the timings to 10-11-10-30.

At a frequency of 1600 MHz, the memory confidently passed all tests with delays of 8-8-8-24 and the results were included in the final tables.

An interesting observation: the first test was rejected because the modules were mistakenly inserted into slots in a single-channel configuration, which is why Apacer memory consistently occupied the worst places in the tables. After the error was discovered, all tests were repeated, and the same RAM with the same working timings began to claim the top lines in the charts. The impact of dual-channel mode on performance is extremely large.

Corsair Vengeance

Even without putting this memory on a stand, you can confidently predict victory for it. The timing formula indicated on the packaging is impeccable; there is practically nothing to add or subtract here. But a detailed study of the contents of the SPD showed that, although in small ways, some things would have to be corrected.

Judging by the numbers in the far right column of the SPD table, when selecting the XMP profile, the kit is inoperable. They haven't yet come up with DDR3 chips capable of operating at 2133 MHz with CAS# Latency=7, and even at undervoltage 1.5 V.

And now the most interesting part - overclocking. Without a noticeable increase in the supply voltage (to guarantee its value was 1.55 V), the Corsair set started up at 2400 MHz and timings 10-11-11-30. And every single test passed without errors!

Judging by the results of all AIDA tests, it is the kit from Corsair that has the highest speed characteristics

There were also no complaints about memory operation at 1600 MHz with timings of 8-8-8-24, and the throughput turned out to be very, very high. We can safely recommend the memory Corsair Vengeance enthusiasts.

ADATA XPG Xtreme Series

The first memory kit that can work without additional study of the settings, if the motherboard allows the use of the XMP profile. The settings for the 2133 MHz frequency stored in non-volatile memory fully correspond to the recommended ones, and, most importantly, the computer starts up perfectly.

"Passport" of the ADATA XPG Xtreme Series kit. The memory will remain operational at any frequency; timings can be safely left in Auto, if you do not try to squeeze out maximum speed

Initially, there was increased attention to ADATA memory sticks. The combination of timings 10-11-11-30 at 2133 MHz seemed too stretched. But practice has shown that this is not entirely true, but there is some truth in this statement. And this was confirmed during experiments with the Command Rate parameter. By default it is supposed to be set to “two”, it will also be selected if you specify Auto in the CR settings. ADATA memory also worked with CR=1, but some of the computational tests were “flunked” even at a frequency of 2133 MHz, without any overclocking.

The Super PI 32M “calculator” was launched four times, but stopped with an error on the 10th – 11th pass. Neither lowering the voltage to 1.6 V nor increasing it to 1.7 V improved the weather, so it was decided to leave CR=2, as recommended by ADATA

It turns out that these strips will not allow overclocking, since the parameters are extremely tightened? We thought so too, but in reality the situation turned out to be much better. Quite surprised, we observed that all tests were completed at a frequency of 2400 MHz, and the delays did not even have to worsen: the memory worked best with a combination of timings 10-11-11-30 CR2.

After minor manipulations with the settings, the ADATA kit began to deservedly claim victory in today's competition

It turns out that the first assumption about the overclocking potential of the ADATA memory kit turned out to be wrong; these sticks contain considerable reserves. Needless to say, 1600 MHz with timings of 8-8-8-24 were played like clockwork, the tests were passed with very interesting results, about which a little later.

Geil DDR3 Evo Corsa

Geil memory frequency of 2400 MHz is shown by the manufacturer as nominal. At least that's what the packaging and booklet say. Let's see what parameters are recommended by the manufacturer and do they match the declared ones?

The XMP profile is written perfectly, and the frequency, timings, and supply voltage correspond to the declared values. It can be said that with the Geil memory kit there will be no problems with the first launch

But aren't the "12" values ​​in the RAS# to CAS# and RAS# Precharge lines too big? It is quite possible to lower them by 1 point, only after that you will have to check the platform for stability, which can be entrusted to our set of tests. The result of timing selection was as follows:

Walk, walk like that! The CAS# Latency value was also reduced to 10, which did not lead to system instability

Great result. This memory works ideally at a frequency of 2400 MHz and the test results only confirm this. Unfortunately, the same cannot be said about stability and performance. Geil Evo Corsa at a frequency of 2133 MHz. In order to maintain the optimal balance of speed and reliability, we had to search for the correct timings almost blindly and it took a fair amount of time. The tRAS parameter unexpectedly showed its essence. Until we set it to "28", performance was very poor. The final results of tests at a frequency of 2133 MHz included the results Geil Evo Corsa with parameters 9-10-10-28 CR1, almost like the Corsair memory.

It took a lot of time to improve latency this much.

According to AIDA, the increase in speed after overclocking is not as noticeable as we would like. You will be able to see it only in comparative diagrams, in real work it is unlikely

Let us summarize the preliminary results. Geil has again got the perfect set of RAM, which allows you to try overclocking using all available methods, both in terms of frequency and reducing latency. With such excellent characteristics, you can count on “Gale” to take prizes in today’s test. It’s strange to use such high-speed memory at 1600 MHz, but we still tried this option, running a set of tests with timings of 8-8-8-24. This will give you the opportunity to compare Geil bars with their competitors.

Kingmax Nano Gaming RAM

Now we have come to the most interesting memory kit. First, let's look at the table of default timings and see its contents.

The XMP profile is registered correctly, but the high supply voltage of 1.8 V is alarming. Intel does not recommend setting it above 1.7 V to avoid damage to the memory controller in the processor

The first launches at a relatively safe voltage of 1.7 V ended in failure; the bench computer refused to start. Even raising the voltage to a maximum of 1.8 V and higher to 1.85 V, it was not possible to make the memory operate at a frequency of 2400 MHz.

Even our overclocker-tolerant motherboard thought that 1.8 V was too much, highlighting the line in yellow.

After several dozen experiments with increasing and decreasing timings and voltage adjustments, the computer began to run stably at a frequency of DDR 2400 MHz, with timings of 10-11-11-31 CR2, but the timing values ​​were displayed incorrectly in the CPU-Z utility, and test runs AIDA utilities, Super PI 32M, archivers, showed that the results are very low, the same memory at a frequency of 2133 MHz is faster, so it was decided to leave the results obtained at a frequency of 2133 MHz in the table, and the test Kingmax Nano Gaming RAM do not carry out at a frequency of 2400 MHz. Kingmax commented on this situation as follows: the company did not conduct a detailed test of this memory on the platform we used, and Kingmax does not guarantee the stability of Nano Gamning RAM, and recommends using Kingmax Nano Gaming RAM on Intel platforms. However, we also noticed that there is no stability at all, and the dual-channel mode is completely ineffective. We did not increase the memory voltage to 1.9 V, fearing for the health of the test bench components.

The optimal timing formula for working at a frequency of 2133 MHz turned out to be 9-10-10-24. She also had to be selected manually. The already familiar “three eights” at 1600 MHz were easy.

Now as for the wonderful coating of the chips. At such a high voltage at maximum load (archivers, Super PI 32M), the temperature of the microcircuits reached 37 - 39 degrees. In a closed stand, the heating will be higher, but not fatal. Nanoradiators work, they cope with their tasks, but what else do you need from them? You still can’t see the beauty in a closed system unit.

Feelings from Nano Gaming RAM remain mixed. On the one hand, this is really fast overclocker (gamer) memory with modern chips. But in order to make the RAM work at the rated frequency, you need to have a lot of experience in BIOS settings, at least have a general idea of ​​how the RAM works and know the typical delay values. Moreover, there is absolutely no guarantee that your memory will eventually work.

And the supply voltage is generally a puzzle. The module packaging indicates a supply voltage range of 1.5–1.8 V. According to the specification, 1.8 V is required to start at a frequency of 2400 MHz, but as the frequency decreases, the supply voltage can be lowered. Everything is on a whim, since Kingmax did not leave us exact instructions.

DDR3 memory tests | Test results

In order not to clutter the article with a huge number of screenshots and not to force the reader to find the necessary numbers on their own, all test results were summarized in several diagrams, in which memory kits from one manufacturer are assigned a specific color, selected according to the color of the radiator or packaging. It is also necessary to note that in all diagrams the scale of values ​​is relative, so a twofold difference in the length of the bars does not mean a twofold difference in speed. The results are grouped by applications in which memory was tested. And for each participant, its clock frequency and the set of main timings at which it was tested are indicated. Obviously incorrect results are not shown in the final diagrams, and test results in the Super PI 32M benchmark were not used due to poor repeatability of the results.

Archivers

The built-in WinRAR benchmark gave preference to the Geil kit, and in general it is clear that high frequency Memory performance has a beneficial effect on performance. So almost all the kits that were able to pass the tests at 2400 MHz turned out to be winners.

At the bottom of the list, as expected, was Goodram memory at a frequency of 1333 MHz with short timings, and Nano Gaming RAM was also there, operating in single-channel mode at 2400 MHz, which is why it was removed from the race and removed from the charts. The results of a newcomer to the memory market, Apacer, are predictable, but pay attention to the noticeable increase in performance of Apacer after selecting the timings! Another interesting conclusion can be drawn from the same diagram: if your platform does not support working with memory at frequencies above 1600 MHz, there is nothing to be upset about, the difference between the results at 1600 MHz and 2133 MHz is small. Having an outdated motherboard, it makes sense not to chase megahertz, but to shorten the delays.

7-Zip has different compression algorithms, so the results will be different. But the general trend is similar. The best results are collected at 2400 MHz, and the positive impact of short timings (Geil, ADATA, Corsair) is very noticeable. Let's look at the results of the 7-Zip built-in "packaging" test.

Among the laggards is again the slow Goodram at 1333 MHz, which managed to outperform itself at 1600 MHz. Obviously, short timings for 7-Zip are not critical. But then there is nothing to explain why Corsair did not take first place, losing to Geil and ADATA.

In the "unboxing" diagram of the same built-in 7-Zip test, the results are even more interesting.

The outsiders have pulled themselves up to Olympus, and the former winners are bored in the rearguard. Apacer at an average frequency of 1600 MHz took third place, Goodram took the lead at 2133 MHz. It is absolutely impossible to understand the reason for this arrangement of test participants, so it is worth looking at the table with the final 7-Zip testing rating.

7-Zip calculates results in MIPS, which is an acronym for Million Instructions Per Second.

Now, the situation has become noticeably clearer. High-frequency memory gains a maximum of "Mips", reducing the clock frequency leads to a uniform decrease in performance. The results show the success of ADATA, Geil, Corsair, Goodram memory. Kingmax is not among the leaders, having consolidated its position in the middle. Apacer does not take first place; short timings at a frequency of 1600 MHz for its chips turned out to be more preferable. And in general, the impact of delays is noticeable. Look at Geil Evo Corsa, what is the gap at 2400 MHz with timings 11-12-12-30 and 10-11-11-30. Here you can clearly see which memory at 2133 MHz copes with a bang, and which is trying its best.

AIDA: cache and memory test

This benchmark allows you to evaluate the performance of the memory subsystem in read/write/copy operations, as well as measure latency, which strongly depends not only on the memory used, but also on the DDR controller that is built into the CPU. The lower the latency, the noticeably higher the computer's results in all tests. The AMD platform has a latency of 45–60 ns, while the latest Intel processors demonstrate 38–45 ns in tests. You can reduce latency in several ways: by overclocking the CPU, shortening timings, increasing the memory frequency. Since we are not touching the processor parameters today, the latency will depend solely on the properties of the chips and the configured memory parameters. But we will start the analysis not with latency, but with a linear reading test.

We have already seen something like this picture. It is quite possible that AIDA most truthfully ranked memory based on its performance. But we identified the obvious leaders in advance; it’s more interesting to look at those lagging behind. There we can see that Apacer's performance at 1600 MHz is not ideal, but if we move to 2133 MHz, the results are clearly better. The same picture with "Gale". But Kingmax Nano Gaming RAM clearly not eager to take the lead, taking only sixth place at 2133 MHz.

In the write speed test we will see the same trend.

And again ADATA, Geil, Corsair took the prizes, but look how high Goodram (1333 MHz) climbed! Of the other kits, the kit from ADATA still works well at a low frequency of 1600 MHz; our “dark horse” goes very confidently, if not rising to an inaccessible height, then occupying very prominent places. A Apacer does not increase speed much with shortened timings, but it turned out to be first in the “2133” group in nominal mode. You can also immediately see the breakdown of all participants by clock frequency.

But here is a not the most obvious copying test, in which the contents of one cell are copied to another. Its impact on real-world applications is controversial. Let's not make hasty conclusions, just let's see what happens.

As they say, “all the same faces.” ADATA is in the lead along with Corsair and Geil, Apacer even at 2133 MHz with timings of 10-11-10-30 is no faster than with timings 11-11-11-30. In the "1600" class, ADATA performed on an equal footing with Apacer, and Goodram did not present any surprises this time. Based on the tests already completed, everything is quite clear, but we still have a lot of interesting things in store. Finally, we come to the latency test. Since the lower the latency value, the better, the diagram turned out to be upside down, but thanks to this, the winner should still be looked for at the bottom of the diagram.

Goodram DDR3-2133 was again included in the list of winners, but competitors with a frequency of 2400 MHz did not allow it to rise to the very top. In addition, the work of the Polish kit is more low frequencies turned out to be surprisingly slow. Apacer memory performed well; its three blue bars are evenly distributed in the diagram. Kingmax at 2133 MHz beat Geil by two points with almost the same delays.

SiSoftware Sandra, cryptography and encryption

Let's look at the summary chart. It can be seen that the results for almost all participants are similar; it looks like an array of columns of almost the same length.

And again we see a clear ranking of memory sets. High-speed modules occupy the best positions; as the frequency decreases, they also show a uniform decrease in performance. Exception from general rule become Apacer, Goodram, Kingmax. The first one got far ahead (the test was carried out 4 times with the same result).

Goodram was inferior to all competitors (although, as we found out, judging by the latency it is very good), and Kingmax DDR3-2133 never woke up and remained in the middle. Let's see if the picture repeats itself in the next SiSoftware Sandra test?

Yes, it turned out almost like a carbon copy. The nature of the task at hand has changed, but we again see a tight block of top performers and a few lagging sets.

PC Mark 7

Let's see if PC Mark's comprehensive suite of tests sensed a change in memory performance.

If you look at the distribution of results, you can see that PC Mark gives preference to high-speed memory 2400 MHz, it is also sensitive to short timings, it is for the latter reason that Kingmax DDR-2133 9-10-10-24 outperforms Corsair DDR3-2133 9-11- 10-30. But, as in all other tests, short delays do not help Goodram DDR3-2133 9-10-10-26 become the test winner. From the diagram we can conclude that memory frequency and its delays have a direct impact on the speed of content processing. Maybe by five percent, but a computer with high-frequency memory will be faster. And this factor, among other things, will help save professionals’ precious working time.

The next test is also very indicative; it is a test of the speed of performing Internet tasks.

A different distribution of colors in the chart is immediately noticeable; of the recognized leaders, only Corsair remained on the pedestal, and the prize positions are occupied by former outsiders. And in general, all memory with a frequency above 2133 MHz is “rejected”. There are no objective reasons for such an outcome; rather, it seems like a random result, so we can say that there is no influence of the frequency and timing of RAM on computer performance in typical Internet tasks.

There is no point in presenting one of the diagrams. According to the results of the graphics test, it was not possible to detect a direct effect of RAM frequency on FPS, which is not surprising. Typical values ​​in Graphic Test 4 on the “Performance” presets are 42 – 44 fps, and it was not possible to achieve approximately the same result even under ideal conditions, so we made a mental note and excluded the results of this test from the final.

But there is definitely a direct relationship between the speed of calculating physical models and the parameters of RAM. Moreover, the physics test in 3D Mark 11 is a great option to test your computer's stability.

A very, very significant result. There is a noticeable increase in results with high-speed memory; if you look closely, you can see that memory sets with the same clock frequency score approximately the same number of points (the results are arranged in blocks), timings in this test almost do not play an important role, but in fairness it must be said that the impact of delays is all -this is true. It turned out that in the physics test there is practically no difference between memory with a frequency of 1600 MHz and 2133 MHz, if the first has the timings correctly selected. So gamers have something to think about.

DDR3 memory tests | conclusions

Today's testing of DDR3 memory, carried out in the THG laboratory, was very extensive, but it allowed us not only to answer the question “whose memory is better,” but also to identify non-obvious dependencies between memory characteristics and its performance. But it’s better to first summarize the impressions of all test participants one by one.

>Goodram Pro, in general, should have competed out of competition, the reason being the capacity of 2 GB per stick, and not 4, like the competitors. In addition, it was not possible to overclock it to 2400 MHz. Positive characteristics include operation with a supply voltage of 1.5 - 1.6 V, and the possibility of overclocking by reducing delays. These modules performed well at clock frequencies of 1333 MHz, 1600 MHz and 1867 MHz. At a frequency of 1867 MHz we managed to limit ourselves to timings of 8-9-9-24, which is very good. We can recommend this memory to owners of AMD platforms. At 2133 MHz Goodram is functional, but its results are quite low, so it’s worth choosing other modules to equip modern Intel platforms.

Apacer Armor Series can be considered a rather strange debut of the company on Russian market. The advantage of this set should have been its low price, but it is still unknown to us. But the shortcomings have already been discovered: the thermal interface is of low quality, with poor adhesion, average performance, poor suitability for overclocking. However, everything is said above, there is information in the diagrams. There is not enough information on the cost of the kit to make final conclusions Apacer Armor Series, but it is clear that for “every day” computers, such as office or multimedia ones, it is enough, and it should not fail.

Corsair Vengeance- the clear leader of today's test, captivated us not only with its excellent, and most importantly, simple overclocking, but also with very high results in tests both at 2133 MHz and at non-standard 2400 MHz. If you spend some time and properly arrange the sub-timings into optimal values, you can get even more pleasant results. The only disadvantages of the Corsair kit are the high radiators, the need for which is not obvious. This high-speed memory will appeal primarily to gamers and overclockers, especially if their platform allows the use of memory at a frequency of 2400 MHz.

ADATA XPG Xtreme Series can be called the discovery of today's test. The nominal characteristics cannot be called either successful or advanced, but in fact this “simple memory” turned out to be an overclocker, easily reaching 2400 MHz, while showing the best results in almost all tests. No shortcomings could be identified. The peculiarity of ADATA boards is that they require control of the value of the Command Rate parameter in the BIOS, reacting very negatively to “one”. It's better to put a "two" immediately after the first turn on. The ADATA DDR3 kit is well suited for compact computers; this memory has very compact heatsinks.

Geil Evo Corsa- another today's leader on a par with Corsair. At a lower cost, this memory has a higher nominal clock frequency, excellent characteristics, and is suitable for serious overclocking by reducing timings. Among the shortcomings it is worth highlighting not very high performance at a frequency of 1600 MHz, so this memory is more likely for adherents of Intel platforms. For getting good results you don’t have to spend hours selecting settings; the XMP profile is written quite correctly. The disadvantage is the same as that of Corsair - a high radiator. This will not prevent memory from receiving our recommendation, but it will block its access to HTPCs and embedded systems.

Kingmax Nano Gaming RAM– innovative memory – turned out to be a very capricious person. Firstly, its “native” frequency is 2133 MHz, not 2400. There is no doubt that with a long “polishing” of the timings it will be possible to make it work at a frequency of 2400 MHz, but the parameters recommended by Kingmax are not optimal. This DDR3 kit can be recommended to trained users who are able to independently conduct a set of tests and adjust parameters to obtain maximum performance. The greatest bewilderment is the supply voltage at a frequency of 2400 MHz - 1.8 V or does it still need 1.9 V? Other participants needed 1.65 V, while Corsair and Goodram were content with 1.5 V.

Does it make sense to select high-speed memory for your computer? Of course, yes, if we are talking about assembling a powerful system unit. The difference in the memory test results at 1333 MHz and 2133 MHz is very noticeable. But even if the maximum frequency of the memory controller in your computer does not exceed, say, 1600 MHz, with good memory, finely adjusting it, you can achieve good results in this case, which is clearly confirmed by the test diagrams.
