OCZ Technology is one of the most prominent memory manufacturers. It was among the first to ship a memory product supporting EPP technology. The OCZ PC2-7200 EPP modules are designed with advanced SPD settings to allow compatible motherboards to recognize and utilize the added operating data, ultimately increasing the performance potential of the entire platform. This equates to overclocking capabilities for inexperienced users and gives the highest possible performance. The PC2-7200 Platinum EPP is designed to run at 450MHz, with enhanced latency of 4-4-3-15.
According to our tests, the memory reached an impressive 564MHz with voltage up to 2.25V. The overclocking potential is excellent with this memory. You can either select low CL3 latency at DDR2 667 or CL4-4-3-15 (DDR2 889 ratio) and gradually increase FSB up to 381MHz with absolute stability! It's very possible that you can achieve even lower latencies than 4-4-3-15 with increased memory voltage, but that depends on your own setup. We were able to reach 1150MHz with 2.25V. However, our system was not 100% stable, and perhaps with a higher voltage than 2.25V, you can achieve even higher speeds.
The most exotic feature of these modules is of course EPP technology, which hasn't been tested in our labs...Why? Simply because EPP works only with Nvdia 590SLI enabled motherboards and our standard testbed board for all memory tests is based on the Intel 965Express chipset.
We were so impressed from the overclocking capabilities of these modules, that we believe you won't need to look around at PC2-8000 or PC2-8500 rated memories. The retail price of ~US$400 is higher than what you would pay compared with other PC2-6400 products, but that is outweighed when you look at the performance. Also consider that PC2-8000+ memory modules cost a lot more (US$500+) so you could say it's a bargain :-)
Overall, a highly recommended product, especially for overclockers!
