While changing the memory speed between 800MHz and 1067MHz  inside the BIOS resulted in only marginal performance gains, going the whole hog and overclocking the FSB, processor and memory resulted in some very impressive performance advances. Running our 2.4GHz processor at a FSB of 333MHz and the memory at 1000MHz resulted in a whopping 26 frames per second increase in our F.E.A.R tests. Okay you can't guarantee results like this unless your using high end equipment and good cooling but we have found the Core 2 Duo 2.4GHz processor very easy to overclock on stock cooling up to 300FSB without any increases in voltage. If you plan on doing this, the Vitesta Extreme Edition really comes into its own with power house performance. In fact it's so flexible you could run at 300FSB and 1000MHz, 333FSB and 1000MHz, 356FSB and 1068MHz or 400FSB and 1000MHz without fear of the memory holding you back in your overclocking attemtps.

Bottom Line

A-DATA have produced an excellent set of DDR2 modules well worthy of their Extreme Edition label. Any Intel or AMD system would benefit from the Vitesta range but the real performance advantages come with overclocking. Equip your system with Vitesta Extreme Edition 1000MHz modules and you'll be able to take full advantage of Core 2 Duo and AM2 processors at high front side bus speeds.  In games such as F.E.A.R we saw a 20+ frames per second improvement just by upping the FSB to 300 and running the memory at 1000MHz in our Core 2 Duo system. If your system can take it you'll be pleased to hear these modules have plenty in reserve and can push onto 1100+MHz at 5-5-5-15 timings. At around £200 for a 2GB dual channel kit they represent fantastic value for anybody looking for high frequency ram.
