I7 CPU won't cold boot?

So I'm trying to undervolt + overclock, or just plainly undervolt.

However, even though my computer passes hours of Prime95, it doesn't boot up after it is turned off for a few hours - I suppose bootup requires much more cpu voltage than when it is running at load.


OCed to 3.0GHz
So far, I've tried to up 1.1325/1.1350 volts and it doesn't boot. Any recommendations? (both for OCed speeds and for keeping it at stock)

It's annoying to go through trial and error, since I need to restart it like 5 times so the BIOS resets...it'd be easier if someone told me their voltage settings for an i7 overclock or undervolt.

Any voltage suggestions?

We might be able to give you some better answers' if we knew which Core i7 motherboard you have and what Bios' revision it currently has on it.

Hope these help you out, Good Luck.

I had this same problem with my P4 on an Asus board (started happening after it was 4 years old). The fix was to increase the Vcore, overclocked with extra voltage it'd start everytime, but on stock settings it'd take a few goes.

Put the same chip in a new motherboard 2 months ago and never had the problem.
