Upped it to 1.37v, gonna try again

bump the vcore twice and you shoudl probably get an hour or two in blend test, then try increasing the vccio to 1.125 and see if that increases the prime blend more. When you reach 8hours or so, and if it bsods, try not to increase anymore vcore, try messing around with the VCCIO and you could get it pass the 8hr mark.

Good luck

You should be able to get around 4.7ghz with that voltage, but as every cpu is different it might not be possible. Check the chart on my thread, sorted by overclock and sorted by voltage can give you an indication of what people are running. Lowest 4.5ghz voltage I have seen stable was with 1.272v and highest I has been 1.368v. If your looking to stay at 4.5ghz I would lower the vocre a bit and see if you can get that stable with around 1.32v. It seems that maybe you have been a bit unlucky with your chip.

Hope that helps.

What's the VCCIO and how does increasing it effect the OC? I saw someone recommend bumping it up to 1.125 to help stabilize it.

IIRC its the VTT/QPI voltage, increasing it can help stability.

(sorry for the noob-like questions, I'd rather ask 'em all here than make multiple threads)

did you disable spread spectrum?

did you double check? try disabling the c states and speedstep. Also what bios are you running?
