To low it won't properly start. To high it goes BANG.
Set the Vcore under 1.37, and run it at load, use prime95 or intel burntest to check for stability. If it doesnt fail or lockup, drop it a couple, 1.34, and retest. just keep going.
I tuned it down to 1.325v and it seems to work fine stability wise, the temp is at 50-55C in full load. Thanks!
Btw, what's there to think about when overclocking my GPU (GeForce 8800GT)?
Do I only have to think about the temperature and stability, and what's a good temperature?
Currently my GPU is running at 50C idle and 62C full load.
