Hi, I've got my i7 930 running @ 4.3 with 1.312 vcore. Prime 95, OCCT, LinX stable. Memtest passed 5 times with no error. But, everytime I turn on my PC (more than 6 hours off), it always fail to boot. It just force itself to default settings. I have to reset and load OC profile again. What's going on?
