I'm running an E6600 that runs 2.4GHz stock at 3GHz with a good aftermarket cooler (temps never go above 48C at full load). The CPU is overclocked and *undervoltaged* (1.29V from its 1.35V stock). The RAM is both underclocked (to get an FSB:DRAM ratio of 1:1) and undervoltaged. The system has been confirmed stable though; 8 hours Prime95 stress test with no errors, which is much more of a stress test than any real application can pull off. It also passes memtest. > Do you run the proprietary nvidia-drivers?

Didn't think that this has anything to do with it though. Can you recommend a Linux program that does a stress test like Prime95 on Windows?
