A-Data Vitesta 2GB Extreme DDR2-800 Review



Computer memory has been getting faster and faster the past few years, yet it is still one of the slowest bottlenecks in our systems.  If you’ve purchased a compuer or motherboard within the last few years, then the chipsets require use of DDR2, which range in speeds from 553Mhz to over 1 GHz!

RAM has also been getting cheaper over the years (especially if you factor in price vs. performance), but we still want to get the most performance out of our memory as possible.  You can purchase a “budget” set of RAM, but you are almost guaranteed to have no overclocking headroom.  Better (and generally more expensive) memory runs at faster timings (4-4-4-12 instead of the standard-5-5-5-15).

A-Data has released their Vitesta PC2-8000 RAM, which is technically a DDR-800 set, but  with a guaranteed overclock to DDR-1000 Speeds.  This overclock translates into a 25% performance increase (8GB / second vs DDR2-800’s 6.4GB /second).  This also means that you can re-use this memory when you upgrade your motherboard to one that supports a fast 1GHz bus.

A-Data is a well-established memory manufacturer, but has been more popular in Asia and is now marketing its quality products in the Western world.  Our first review of A-data’s products impressed us quite a bit, and we were especially delighted when we looked at the specs of their Vitesta Extreme Edition DDR2 Memory.

Product Description

Although the bandwidth has increased about 20% from DDR2 667 to DDR2 800 (5.3GB/Sec vs 6.4GB/Sec), however, based on the JEDEC standard, the CL (CAS Latency) is 5 for both DDR2 667 and DDR2 800. A-DATA’s DDR2 800X has effectively worked out the latency issue, with CL reaching 4, and tRCD, tRP and tRAS improving to 4-4-4-12, greatly surpassing DDR2 800’s 5-5-5-18. The performance is nearly catching up to DDR2 1000. All of this excellent performance quenches gamers’ and overclockers’ thirst for speed.

With dual channel motherboards getting increasingly popular, A-DATA releases these new Vitesta DDR2 800X modules in matched pair kits that provide users with guaranteed compatibility. All A-DATA Vitesta series modules pass A-DATA’s rigorous dual channel testing, so users can rest assured their platforms will perform beyond their expectations.
