"I set the voltages at my usual 2.8V ceiling and started increasing by 5MHz increments on our trusty 2.4C/AI7 system. At 230MHz I was assuming we'd already done pretty well and would be at or close to the limit. I also thought that at 235MHz, then again at 240MHz, and 245, and 250, and 255, and 260! Yup, at 260MHz I could boot into and use Windows with no problems at all. Unfortunately anything more stressful such as 3DMark was pretty unstable and I had to throttle back to 255MHz in order to get everything running perfectly. Just a reminder, that's a 55MHz overclock on a dual channel memory system using value series memory!
Because I had no idea where the limit was I ran a few benchmarks at each setting and thought it might be interesting to look at how the memory performance scaled at these different speeds:"
