Have a Core2 Q9550 stepping A Rev E0 which as I understand it is supposed to be a more oc friendly revision. Stock speed is 2.83, I have it running at 3.612. From what I've read 3.8, even 4.0 is supposed to be very doable but so far I haven't been able to get there. Tried various profiles I've seen online, various voltages but so far anything over 3.6 either is unstable or won't even get to the desktop.
Have it on a GA EP45 DS3L mobo, running Win7 64 home prem, 8 gigs ram, SSD drive.
This is the profile I'm using for 3.612 - thanks for all input.
