A-DATA Vitesta Extreme Edition DDR2 800 Unlike most other DDR2-800 memory, the Vitesta Extreme Edition has a CL rating of 4. More interesting is the fact that it achieves it by running at 1.8V. We had absolutely no problem with it getting detected by the motherboard and auto SPD (Serial Presence Detect) had it running at the rated speed. If you want to set a slightly aggressive setting, you need to enter the BIOS menu so a flexible motherboard with decent BIOS is as important as the high performance memory you want to run on it. The model we received came in a pair with 1024MB on each DIMM. It also supported EPP (Enhanced Profile Protocol) which is an extension to the SPD specification and adds reliability. We ran it at the rated 4-4-4-12 timings without any issues related to stability. Everest Ultimate Edition was used to test its read, write and latency performance and we compared it to a low latency solution from Corsair. The Corsair had a more aggressive setting of 3-4-3-9. The A-Data module did well, getting a score of 66.1ns in the latency test. That beat our previous best OCZ (PC2-6400 Platinum kit), but could not match the Corsair at 62.4ns. In the memory read test the A-DATA memory managed a bandwidth of 7095 MB/s, which is again impressive, but not the highest we have recorded.
