Hi everyone!
I have x975xbx rev305 with 9-11 BIOS 1542. I have set FSB to 20%boost. Double Prime ran without any issues for 3 hrs when i shut it down, but superpi 32M run made my PC reboot. I assume I don't have enough Vcore, but can't find where and how to raise it??? cpu-z says it's 1.213V, while IDCC says it's 1.4V. I was thinking of raising the Vmch and FSBv, but i don't know how much? what are the defualt values so I could know how much to raise them?
I have E6600 step.6 rev2, 2x1Gb DDR2 Supertalent 1000MHz (set in bios to 800MHz 2:3). i don't think it's a ram issue - it was at 880MHz 5-5-5-15 1.9V.
how can i raise Vcore?
