You have a Q6600 G0 from Frys as well? I was thinking on doing te vdroop penicl mod on mine as well and see what happens. I saw the picture for the formula but seems no one confirmed it works on the extreme. Also I thought the Loadline Calibration was to prevent vdroop? I think my bios is 1.45 and everest reads 1.43 or 1.44 I think.
Sorry It could be me, I dunno. I am gonna try 8*400 and see if I can stable out. But if I cant get this stable even at 2.5ghz than I am gonna call and send it back and get Q9450.
Maybe its the fact that am using the stock cooler but my temps aren't that high. I know it cant be my board or ram because my E2160 was fine. My bios supports my quad. But I still find it funky that I cant be on default with my Q6600 in bios to even start my computer.
Would reinstalling windows help out maybe?
Maybe reinstall Vista?
