I'm trying to run 7x400 fsb on my E6600 and I was hoping it would work at that lower multi so I could reduce vcore and therefore bring down temps at load on the cpu.

Dosent even get to the post screen and I have to power off to get back in the bios.

I'm running at the mo - 9x333fsb mem @ 833mhz vcore and mem volt auto, and nb/sb 1.50v/1.05v

Any ideas?
