Right I've got a problem here,

I sold my E6600 like an idiot to partly fund my upgrade (DFI P35, and a Q6600 which I've received the quad but waiting on the P35). I forgot to backup the data off my ICFX3200 RAID 0 array so decided to put the quad in to burn the data onto some DVD's.

Problem is, I get to the post screen to which is comes up with CMOS checksum error which s a standard error when you've cleared CMOS. So I pressed DEL to get into the setup screen but it just goes onto a blank screen and nothing happens.

Diagnostic LED says 7F.

The other weird thing, is that the post screen says my Q6600 is running 600x9 600Mhz.

The bios is the 2/12/2006 (shipping bios) as the board hasn't been used for a long time and was put away when all the new bios' came out.

I'm sure the shipping bios' supports quads, as the release notes for 2/12/2006 is some sort of fix for QX6700 processors.

Any ideas?
