A-Data Vitesta X DDR3

Benchmark Reviews has amassed the largest collection of DDR3 memory modules anywhere, and we are now ready to showcase the thirteenth product of our High-Speed DDR3 Review Series. In this article, we test the performance from A-Data's Vitesta X series DDR3, and discover if this overclocker-specific system memory is built for the task. Rated for 1600MHz, Benchmark Reviews successfully pushes the AD31600X002GU well beyond its PC3-12800 rating without disturbing the low 7-7-7-20 clock latency.

DDR3 Memory offers such a high front side bus to overclockers that CPU speeds can reach well beyond extreme. A-Data has produced the Vitesta X 1600MHz DDR3 PC3-12800 CL7-7-7-20 AD31600X002GU 2x1GB RAM kit for hardware enthusiasts to take advantage of. Benchmark Reviews has discovered more overclocking headroom in these modules than nearly all the others, which could make or break the most performance-critical overclocking project.

System memory (RAM) manufacturers are in a tough position these days. Everybody wants the latest technology which runs faster and operates more efficiently, but nobody wants the price tag that comes with it. Because DDR2 fabrication assembly plants are nearing obsolescence, the equipment depreciation has caused DDR2 prices to drop very near to the actual cost of production. This is bad news for the manufacturer, while conversely it means great savings to the consumer. So while manufacturers try to squeeze the last drops of revenue out of DDR2, along comes DDR3.

Since JEDEC is about to finalize 1600MHz as a standard DDR3 speed, many kits which were once considered High-Speed will now be relegated to standard speed parts. This means that high-grade components such as A-Data's Vitesta DDR3-1600X will lose the "High-Speed" designation and be relegated to standard SPD assigned profiles. But until the new standard is made official, manufacturers can still enjoy the premium designation for at least a little while longer.

Many of the readers will probably not consider DDR3 an important part of the hardware market just yet, and in a very few ways I can agree with them. It's expensive, and it's not going to change their system from a 2 to a 10. Nevertheless, I think that this argument only exists if you have missed the point: DDR3 is a more efficient replacement over DDR2 in many different ways, and high-speed DDR3 (presently anything over 1333MHz) is intended for overclockers and enthusiasts almost exclusively. In a year from now, expect to have DDR3 pressed into your new motherboard. However for today, the demand behind DDR3 and its high-speed variants is best met by the growing number of hardware enthusiasts which push their equipment well past the stock settings.

Benchmark Reviews continues on with our High-Speed DDR3 Overclocking and Review Series, and in this article we focus on overclockers and hardware enthusiasts. Many of the kits we have tested so far come right out of the box with uncommon speeds, and others do their best to get there with some overclock induced massages. In this review of the A-Data Vitesta DDR3-1600X system memory kit we offer a product that is both affordable and performance orientated.

All of this is great news for the overclocker, the hardcore gamer, and the hardware enthusiast; which has been the case every time high-end system memory parts arrive to the market. It wasn't all that long ago we all had SDRAM with 1 and 1.5CL timings, and then DDR arrived with CL3. Nobody complained then, so I'm not sure why they are starting now. It was the exact same story when DDR2 arrived to replace DDR; which nearly doubled the timings. So from a technical standpoint we should appreciate that the timings have only gradually increased with the clock speed, because history has proven this to be difficult.

The Patriot DDR3 1866MHz kit we reviewed not long ago presently holds the record for fastest DDR3 module produced, and the Corsair DDR3 1800MHz kit overclocked to 1900MHz which is simply incredible. This kit may not represent their product, but A-Data also offers a Vitesta DDR3-2000X kit which is certain to make heads turn. But to no surprise the price for these products alone is nearly enough to build a nice computer system. It is for this very reason that system builders have been slow to build off of the DDR3 platform: everything looks expensive. Thanks to phenomenal overclocking headroom in the Vitesta PC3-12800 CL7-7-7-20 AD31600X002GU kit A-Data can deliver the best of both worlds.
