Just a quick question. I've been tinkering around with my Phenom 965 and have managed to get it to run stable at 4.2GHz with a voltage of 1.5. I was just curious if this was safe? My Prime 95 temp maxes out around 50-51C. Could I up the voltage to see how far I can push this chip without causing harm? I know the max temp is around 62C, so is this a good idea?
Also, is a 1.5v core a good idea to run a 24/7 overclock?
I have a lot of case ventilation and a CM 212+ with push/pull fans on the chip. (Just an FYI)
1.5V is pretty good for the PII, you can push it higher than that but it's not recommended. I run my x6 1055T @ 1.5V @ 4.1 GHz 24/7 with "Cool n Quite" enabled. There's no difference between 4.2 and 4.5 specially in gaming maybe be a punsh of high scores with 3D mark, and no one reported a stable 4.5 GHz OCing with the phenom II with normal air cooling. So i can emphasize if you want to push it more than that you'll need extreme liquid cooling, and doesn't worth it IMO.
1.5V is okay for 4.2, as you go higher the frequency you higher the voltage. you can push your P II to 1.9V but the question is do you have the proper cooling to cool the CPU ? so i guess your maximum save OC is 1.5V for 4.2, 1.52-1.53V for 4.5 GHz OC.
