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.
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.
