Baseline testing with prime95 (small ffts). I let it run for 2.5 hours. Saw some glitches in CPU-Z where the core speed would flash low and then back up to max. HWmonitor didn't pick this up. Eventually, at some point after the 2 hours of testing HWMonitor shows a min value for core clock of 222 MHz on all cores. Temps were never past 50c during the test and zero errors returned after the test.

I was using the web searching through the forums when the drops were recognized by HWMonitor. Maybe that caused the Core speed dip but I'm not sure.

Also, should all the Cores be at 100% during the test? One or two cores would drop to 30-70% but that's only a 1-2% drop in the total usage. I don't know, it's my first overclock rodeo!
