Bu cevap yanlış anlaşılmaya mahal verebilir. Bellek hızları en başta dahili grafik yongası bulunduran ve RAM belleklerdeki hafızayı atayan işlemcilerde önem arz eder. Eğer harici bir GPU kullanıyorsanız yukarıdaki videoda olduğu gibi abartılı bir sisteme sahip olmadığınız sürece bellek hızlarının çok da bir etkisi yoktur. RTX2080 sistemde elbette 1333MHz bellek kullanmaz kimse; yukarıda farkın bu denli belirgin olmasının sebebi budur anlayacağınız. GPU kaynak tüketim değerindeki farklılıklar da bu sebepli oluşmuş yukarıdaki videoda. Haliyle FPS’ye biraz etkisi olmuş.
Konu sahibi arkadaş gereksiz masrafa veya uğraşa girmemeli kısacası.

End of 2008 / Processors and memory
At the end of 2008, the situation on the RAM market changed dramatically. First, it is expressed in a serious drop in prices for DDR3 memory modules. Secondly, DDR3 memory modules with a nominal frequency of 1600 MHz appeared in a wide range. However, only a small part of buyers will be able to take advantage of such memory. In particular, if a novice user buys a kit like DDR3-1600, he is unlikely to benefit from such high-speed RAM. And that’s why. As a rule, motherboards set the mode of operation of modules such as DDR3-1333 and, as a result, the performance of the memory subsystem in most applications will be at the level of a system with DDR2-800 or DDR2-1066 memory. Moreover, the price of DDR2 memory is much cheaper. Of course, you can go into the BIOS and force the desired frequency. But a user with such a skill can hardly be called a beginner. If a person understands the settings of the motherboard, then he will be able to lower the processor multiplier and increase the FSB frequency to 400 MHz (we are talking about the Intel platform). As a result, the processor will operate approximately at the nominal frequency, but the overall system performance (FSB 1600 MHz QPB, DDR3-1600 memory) will be noticeably higher. For a novice user, this system configuration is not available, since there are no widely advertised Intel processors with a nominal FSB frequency of 400 MHz (1600 MHz QPB) in stores.
The second category of users of DDR3-1600 memory are overclockers who overclock processors to FSB frequencies over 500 MHz. Now it is no longer a problem to find DDR2-1000 MHz RAM, which is necessary for such a configuration. But with serious overclocking (up to FSB ~ 550-600 MHz), the requirements for DDR2 memory characteristics increase so much that it is much more profitable to use DDR3. Yes, it is somewhat more expensive, but it has no restrictions in the desired frequency range. For example, in synchronous mode, DDR3-1333 memory allows you to set the FSB = 667 MHz, and DDR3-1600 memory already has an FSB of 800 MHz!
And finally, the third category of DDR3 memory users are professionals who work with specific software. If the speed of such software is directly dependent on the memory bandwidth, and DDR3 with frequencies of 1333 MHz or 1600 MHz gives a real speed gain, then such users switch to DDR3-1600 almost immediately, as soon as it becomes available.
In today’s review, we will test all the DDR3 memory kits that are available in our laboratory. And let’s start with the A-Data AD31600X001GU modules.
A-Data AD31600X001GU
The packaging of modules is the most beautiful and solid of all that we have seen.
The appearance of the modules themselves matches the box:
The sticker on the packaging and on the modules contains information about the nominal frequency, operating voltage range and timings.
Let’s move on to testing and look at the SPD information:
So, SPD reports that for a nominal voltage of 1.5 V, the maximum (stable) frequency of the module is equal to DDR3-1333 MHz. And indeed, attempts to run these modules at a frequency of DDR3-1600 with Vmem=1.5 V were unsuccessful. Therefore, the user needs to set the recommended memory voltage range (in fact, this is manufacturer-sanctioned overclocking). With a voltage of Vmem = 1.75 V, this A-Data memory worked at a frequency of DDR3-1600, and with quite decent timings:
What’s more, we were able to lower the timings to 7-7-7-20 without any impact on system stability.
As for the overclocking potential of the A-Data AD31600X001GU modules, it is relatively small: the maximum frequency is DDR3-1800 MHz at a voltage of 1.85 V.
Two Samsung memory modules
Consider the next pair of DDR3 modules, this time from Samsung.
However, in our testing they do not count, because they are unpaired (one module — 1 GB, the other — 2 GB), while the rest of the sets are paired, and worked in two-channel mode.
The same chips are installed on both bars:
Initial information about the modules can be found on the labels:
So, the stickers say that the memory complies with the PC3-8500 standard, in other words, the nominal frequency is DDR3-1066 MHz.
By the way, here is the decoding of the DDR3 indices:
Index | Frequency (DDR3), MHz |
PC3-8500 | 1066 |
PC3-10664 | 1333 |
PC3-12800 | 1600 |
PC3-14400 | 1800 |
PC3-16000 | 2000 |
From the SPD information, we learn that Samsung’s gigabyte memory module is capable of operating at DDR3-1220 MHz with 8-9-9-23 timings at stock voltage.
As for overclocking, at the nominal voltage the memory module has mastered the frequency of DDR3-1600 MHz. However, this became possible with a significant increase in timings.
However, if you raise the Vmem voltage to 1.7 V, you can reduce the operating timings to quite reasonable values (8-8-8-20).
We then tested the 2GB Samsung module, which proved to have exactly the same specifications.
Finally, we tested the system with two different sized Samsung modules, and found no performance degradation. In particular, when the Vmem voltage was increased to 1.8 V, the memory worked at the DDR2-1800 frequency:
In addition, with Vmem=1.7 V, it was possible to reduce the timings to 8-8-8-20.
Qimonda PC3-8500
Now let’s move on to Qimonda PC3-8500 memory modules, which appeared in our test lab almost immediately after the appearance of DDR3 memory.
The volume of each module is one gigabyte, and the memory chips of Qimonda’s own production:
Module sticker:
SPD information:
As you can see, the declared frequencies and timings fully correspond to the parameters of Samsung modules. However, the overclocking potential of Qimonda modules turned out to be somewhat different. In particular, at the nominal voltage (Vmem=1.5 V) the maximum stable frequency is equal to DDR3-1333 MHz (with a small margin).
Further, if the user is not afraid to increase the Vmem voltage to 1.8 V, then he can increase the performance of the memory subsystem by increasing the frequency to DDR3-1400 MHz:
or by lowering the timings to 8-8-8-20:
In this case, the most effective direction is to reduce timings, since the frequency margin of Qimonda modules is small.
So, let’s summarize all the results in one table and summarize:
Test bench configuration:
Test Equipment | |
Processor | Processor Intel Core 2 Duo E6550 LGA775 (2.33 GHz; Conroe) |
Cooler | Gigabyte 3D Cooler GP Edition |
Video card | ASUS 8800 GT (GeForce 8800 GT; PCI Express x16) Driver version: 175. 16 WHQL |
Sound card | — |
HDD | Samsung HD160JJ |
Motherboard | ASUS Striker II Extreme on NVIDIA nForce 790 Ultra chipset |
Power supply | FSP 550W |
OS | MS Vista |
Conclusions
Summing up, we note the following. In the year since the advent of DDR3 memory, its technical characteristics have increased, and the price has fallen significantly. In particular, the retail price of a gigabyte Samsung PC3-8500 module is around $45, and the cost of a Samsung PC3-10600 module of the same size is around $55. And, as it seems to us, all budget Samsung modules are made from the same chips (by analogy with DDR2 memory chips). Therefore, if the expected memory operating frequencies do not exceed DDR3-1600 MHz, then you can take cheaper modules with standard DDR3-1066 or DDR3-1333 MHz frequencies. Thanks to the well-established technical process, the overclocking potential of such modules is quite sufficient to achieve the required frequency.
If the buyer does not have financial constraints, and he needs modules with a guaranteed operating frequency of DDR3-1600 MHz, then he has a wide choice. One option is the A-Data AD31600X001GU Gigabyte Module Kit, which costs about twice as much (~$200). In this case, the user will still have to perform overclocking operations, namely, to increase the voltage on the memory modules.
Also keep in mind that despite the memory manufacturer’s warranty and the motherboard manufacturer’s warranty for system performance at 1600 MHz, some combinations may not reach this frequency. In particular, in our test lab there are two or three motherboards on which the A-Data AD31600X001GU modules simply do not work. Therefore, it is important to remember that each combination (motherboard revision + BIOS version + processor stepping + memory modules) has its own overclocking potential, which is not unambiguously determined and not guaranteed by anyone.
— Discuss the material in the conference
RAM or Random Access Memory. For many unenlightened users, this sounds like a diagnosis of an illness or something worse.
In order to fully reveal the topic for yourself, you just need to understand what DDR is. The DDR format is a relatively new type of RAM that has replaced the SDRAM variant. For users of personal computers and creators of components, this opened up great opportunities in terms of performance and speed of computing the machine.
In simple terms, the new type of memory works 2 times faster than the previous and spends 2 times less resources with the same performance and even more (at a frequency of 200 MHz, the output is 400 MHz for the old version). DDR3 RAM can only be compatible with modules like it (DDR3L).
The security key will not allow you to install DDR2, DDR1 RAM, but if this succeeds for any reason (for example, Intel skylake processors are compatible with DDR3, but not DDR3L, this may cause problems with installing an inappropriate RAM model) then there is a risk of damage to the online recorder module itself or to the computer. In turn, versions of DDR3 memory are divided into 7 types (TC — Clock frequency):
- DDR3 800 — 100MHz clock.
- DDR3 1066 — 133MHz clock.
- DDR3 1333 — 166MHz clock.
- DDR3 1600 — 200MHz clock.
- DDR3 1866 — 233MHz clock.
- DDR3 2133 — 266MHz clock.
- DDR3 2400 — 300MHz clock.
However, it is worth mentioning the fact that the list is incomplete and there are RAMs in which the value of the effective speed significantly exceeds that indicated in the list. For example, the maximum specified value in the table is 2400, there are also faster models, such as DDR3-2000, or DDR3-2666, DDR3-2933. They can be compared with the latest type of memory at the moment DDR4-2666, as well as DDR4-2933.
DDR3 1333
The first guest in question belongs to , the third variation of , and therefore operates on the frequency 166 MHz . The first thing a user should know when choosing RAM is for what purposes the computer will be used. Will it be work, entertainment or work related to entertainment.
It is also necessary to take into account those components that are already in the PC or are planned for purchase and installation. After all, not every RAM will work far from every processor and not every motherboard.
DDR3 1600
The second ward belongs to the fourth variation, that is, it works at 200 MHz clock frequency. The increased effective speed, which is 1600 MHz / second , opens up great prospects in the world of computer hardware and its performance.
Comparison and difference between
All indicators will be marked in tables for a visual comparison of two representatives:
DDR3 1333 | DDR3 1600 | |
Form Factor: | SO-DIMM | SO-DIMM |
Memory type: | DDR3 | DDR3L |
Number of contacts: | 204-pin | 204-pin |
Volume: | 2×4096Mb | 4096 MB |
Speed ratings: | PC3-10600 | PC3-10600 |
Buffering: | unbuffered | unbuffered |
Speed: | 1333MHz | 1600MHz |
Voltage: | 1. 5V | 1.35V |
Delay: | 9-9-9-24 | 9-9-9-24 |
Latency: | CL9 | CL11 |
What will be better for whom?
There are a lot of variations of RAM strips, and when choosing, your eyes start to run wide. Clock frequency, effective frequency, bus frequency, cycle time, peak data transfer rate — for an ordinary person, these numbers will not give any useful information, just for such people there are similar resources (as this article). The main thing when choosing is to make sure that the system requirements match the available hardware, take into account what the purpose of using the computer is, read customer reviews and make the final choice.
DDR3 1600 — this memory will allow to process more information in less time . In fact, ddr3 1600 is an improved version of ddr3 1333, which differs in the volume and speed of writing / reading incoming information. For many, this becomes a deciding factor when choosing RAM, but for the average user using the potential of their device to a moderate extent, the difference will not be noticeable.
DDR3 1333 — DDR3 1333 benefits from its reliability , as and relatively inexpensive price of . For the tasks assigned to this storage device, it does an excellent job. Sufficiently high read and write speed, long-term manufacturer’s guarantees speak of its quality. But it is worth considering that this type of memory has an effective transmission rate of 1333 MHz / second.
This will be sufficient for moderate computer use, such as watching movies, surfing the Internet, playing games, etc. But more serious computational tasks in the form of processing video-photos, working with large files, will cause difficulties in the performance of a personal computer. And this once again suggests that it all depends on the needs of the user and the purpose of using the PC.
