[SOLVED] OC Q9650

[Eugene$$]

Mobo is gigabyte p43, on stock i got 9x399, after 400 fsb, its unstable in prime, I want it to be 3.7 GHz (9x412), what is the minimum volts to vcore i need to manually write? thanks.

Whatever the CPU requires to do so. Not going to be a specific answer, every CPU is different. You also need to monitor temperature under load as you increase the voltage. All well and good to be stable, but if you are running the CPU at 100C it will live a short(er) life.

Not familiar with gigabyte but my old Q9650/asus p5q-pro would boot into windows at some unbelievably low vcore. You need to do the same start under 1.0 and increment up vcore until it will boot into windows then stress test raising vcore until you get it stable.
The gigabyte boards were pretty good overclockers from what i remember.

Same here, they were really god like on the lga775, only thing to watch out for is the tempatures.
Tuniq x2 or tuniq x3 will handle them really well with a good heatsink/fan.
