I have to say these Q6600's are kind of quirky. I was doing some Prime95 testing last night, and although I can run Windows all day without a crash at 3.6ghz 1.3875 vCPU, some cores will fail the test within minutes, while others will continue without a problem for hours. All 4 cores weren't stable until I upped the voltage to 1.425. I'm feeling the need to lapp more and more since it appears that my "best" cores run the coolest, and the ones prone to failure run the warmest.

Thoughts?
