SuperTalent Technology is a US based memory manufacturer with a good reputation amongst users for good quality products. The T800UX2GC4 PC2-6400 is designed to run at 400MHz, with enhanced latency of 4-4-3-8.
According to our tests, the memory reached 480MHz with a voltage of 2.25V. The overclocking potentials are superb with this memory. You can either select low CL3 latency at DDR2 667 or select default timings of 4-4-3-8 and test your system's stability. Its very possible that you can achieve even lower latencies than 4-4-3-8 with an increased memory voltage, but that depends on your requirements and some testing. Other reviewers have reached up to 1000MHz with CL5 and 2.45V, but our test attempts failed, since we got many errors at such high speeds.
Ending our presentation of the SuperTalen PC2-6400 2x1GB kit, we were very pleased with the performance and the retail price of ~US$300. There are huge overclocking possibilities and enthusiast users will have find a memory module that keeps its promise and deliver fast performance. Overall, a highly recommended product.
