I built a nice gaming system in Feb 09 around a Q9300 that I got on sale from microcenter. I oc'd it to 3.5ghz with voltage 1.35 (showing up as 1.28-1.32 depending on speedstep in windows 7 x64). See my earlier thread here for my settings: http://forums.anandtech.com/showthread.php?t=270927. (System has changed slightly, see below.)
At the time I ran all kinds of prime 95 torture tests, even looping 3DMark06 over the top of it to try to kill the system. I did intel burn test and had everything passing with flying colors before I left it alone. It ran prime 95 for 36 hours with no errors. I haven't messed with it since then.
But just yesterday I installed a new Thermaltake Frio. I've been folding a lot and my 92mm CPU cooler wasn't keeping up with the heat so well. So after the Frio was on, I pulled out prime 95 again to stress the cpu and see what temps I was getting. I had an error on core 0 within 10 minutes. Shut it down, started again, and same story - error within 10.
So do overclock setting go bad? Do I need to go back in and readjust? Update bios? Any idea what could have gone wrong since I set it up and tested it? At the time it was stable under windows vista, and now we're in windows 7, would that be the difference?
