I'm still trying to decide exactly what clock my RAM is running at on my Epox 8K5A2. I'm running at 172 fsb with mem clock (that's clock, not timings) at "SPD". I'm running latency timings at 2-3-3-6 @ 2.6v. I got the memory to run stable at "turbo" settings (2-2-2-5), at 166 clock, by running the dimm voltage up to 2.9v. I'm planning to clip a copper plate to it soon and try for lower voltage at those timings.
