Introduction
A recent test platform based on a set of logic and Intel P35 equipped with DDR3 memory, showed that at this stage the new memory could not provide visible benefits in productivity compared to the customary high-frequency DDR2 SDRAM. The relatively high delay serial DDR3 modules contribute to the fact that the memory running at a frequency of 1333 MHz, losing the widely speed DDR2-1066 c taymingami 4-4-4-12 in quite a large number of applications of all sorts. However, this state of affairs should not be an excuse to hasty conclusions.

The fact that most speed DDR3 SDRAM, officially supported by Intel chipsets at the moment, is the frequency of 1333 MHz and 7-7-7 timings or anything yet does not mean for those producers modules, which used to go ahead of industry standards. If you watch the news, then you know that the leading producers of memory overklokerskih already supplied to the market DDR3-1600 SDRAM, and are prepared to top sales DDR3-1800. Achieving such a high frequency was made possible by the diligence of the company Micron, which began production of chips Z9, continuing the tradition of famous among DFI chips DDR2 Micron D9, which after the selection and raise the voltage being able to work at frequencies significantly in excess staffing. Although nominally chip Micron Z9 represent chips DDR3-1066, it has allowed the use of their Uplift practical DDR3 SDRAM frequency to a new level. This gives supporters of all the new great cause for hope for the superiority of DDR3 in productivity over DDR2 in real applications.

New memory modules overklokerskie

Super Talent W1600UX2G7
Since the company was the first Super Talent overklokerskoy producer of memory chips zadeystvovavshim Micron to release speed DDR3 SDRAM, begin to get acquainted with DDR3-1600 memory we have from its product.

As for the real capacity memory Super Talent W1600UX2G7, as demonstrated practical testing, they only slightly better than stated in the specifications. Maximum frequency with which the said memory is able to operate stably at various delays at its staffing to 1.8 V voltage are shown in the chart.

Delivery OCZ PC3-12800 Platinum Dual Channel EB Edition standard - a set of standard modules sealed in a plastic package. The fundamental difference OCZ PC3-12800 Platinum Dual Channel EB Edition discussed above to the memory of Super Talent discovered immediately: the company does not become OCZ save on the radiator and furnished by each module from two sides. Despite this "line of chips for" DDR3-1600 from OCZ located only on one side of PCB. Samy radiators are also of interest because it is branded copper mesh plates performed on the technology XTC (Xtreme Thermal Convection), famous for its good performance. Teplorasseivateli have a platinum coating colors, in addition to causing stylized logo Z3.

On one side of each module affixed stickers with the article produce, the frequency and volume of each module taymingami staff. Well, that the information available on the sticker we received a kit, slightly disagree with specification OCZ PC3-12800 Platinum Dual Channel EB Edition, available on the official site.

Practical study dealt modules to the maximum frequency at different taymingah gives the following results.

Frequencies in figure obtained in a certain specification voltage of 1.9 V. I, it must be noted, OCZ PC3-12800 Platinum Dual Channel EB Edition shows better results than the Super Talent W1600UX2G7 taymingah at all. Thus, delays 7-7-7-18 it demonstrates its ability to the stable functioning at frequencies up to 1704 MHz, and the delay of receiving an opportunity to achieve 8-8-8-21 frequency 1808 MHz. When the staffing same frequency 1600 MHz, as shown by tests conducted, OCZ PC3-12800 Platinum Dual Channel EB Edition can work not only with taymingami 7-6-6-20, but with a more aggressive delays 7-6-5-18.

Thus, in general, OCZ PC3-12800 Platinum Dual Channel EB Edition shows better performance than the Super Talent W1600UX2G7. However, it affects the cost. The difference in the cost of these modules with similar sets of features reaches about 15%, which, given a sufficiently high current prices DDR3 SDRAM, resulting in a very solid amount.

Kingston KHX11000D3ULK2/2G
Find a place in our testing and memory modules from Kingston. Although our laboratory modules from Kingston KHX11000D3ULK2/2G and focused on work only with the frequency of 1375 MHz, not to include them in this material, we could not. The point is that Kingston chose another way of increasing productivity DDR3 SDRAM, which is not to increase its frequency, and to reduce latency. So before the kit is able to work about CAS Latency equal to 5, which gives us the full right to be assigned an expressway and overklokerskih.

This striking contrast characteristics Kingston KHX11000D3ULK2/2G attributable to the use of their other chips, which the company manufactures Elpida. Unlike Gigabit chips Micron these chips are 512 Mbit capacity, causing considered "dice" - bilateral. Accordingly, stamped aluminum teplorasseivateli in memory of Kingston installed on both sides of the modules. They have a standard configuration, but the bright blue color, well ottenyaemuyu wearing white and red logos.

Full list of characteristics Kingston KHX11000D3ULK2/2G is as follows:

The practical examination of the capacity of memory booster of Kingston is very curious picture. The graph below shows the maximum frequency at which Kingston KHX11000D3ULK2/2G ability to retain the stable functioning with its staffing voltage 1.75 V.

Although the test timings set of modules Kingston KHX11000D3ULK2/2G show always worse results than products based Micron chips, they are really working with a frequency of 1375 MHz, with taymingah 5-7-5-15 - mode, or to reach OCZ PC3-12800 Platinum Dual Channel EB Edition, or for Super Talent W1600UX2G7.

On raising the voltage on the chip modules Kingston Elpida reacted poorly: while increasing the voltage to 2.1 V maximum managed to build only to 1486 MHz. Thus, Kingston KHX11000D3ULK2/2G interesting only for its low taymingami at frequencies close to 1333 MHz.

As we tested
After a thorough familiarity with the new memory kits overklokerskimi DDR3-1333 and DDR3-1600 itself time to draw attention to their practical performance in real systems. Will the above products provide a higher level of performance than DDR2 SDRAM modules - is the main question standing on the agenda.

As already stated above, the testing DDR3-1600 can only be overclocked systems based on the set of logic Intel P35 Express (currently it only supports DDR3 SDRAM), working with increased frequency FSB. For our tests, we decided to elect the FSB frequency equal to 400 MHz. This configuration engaging in various frequency dividers stand allows memory in 1000, 1200, 1333 and 1600 MHz, which is quite comfortable for us to the next comparison DDR3 memory and DDR2. Accordingly, a test processor was broken up to 3.6 GHz from a 9 x 400 MHz. Testing DDR3 SDRAM described above happened in a system based on a motherboard ASUS Blitz Extreme, productivity same DDR2 SDRAM measured in a similar system built on the motherboard ASUS P5K Deluxe. So speed DDR3-1600 and DDR3-1333 performance compared overklokerskoy DDR2 SDRAM-1000 operating delays 4-4-4-12, and DDR2 SDRAM-1200, with a functioning taymingami 5-5-5-15.
