Default Re: Core i7 Overclocking thread

Well my problem definitely seems to be that the mobo doesn't like OCing 6 dimms. The RAM all checks out fine, and booting with 3gb of either set is no problem.

Also, booting with 6 dimm at stock speeds is stable.

It's just when I try to get 6 sticks to boot w/ OC, I fail at C1 code and get beeping. I tried bumping the QPI PLL incrementally all the way to 1.5, but no avail.

Stable settings for 3.8ghz at boot (4.02ghz with Turbo in Vista)
