Thank's for the tip nibble.

I've been suffering from boot problems with this board as well even though I haven't overclocked it yet. Sometimes it takes 5-8 power on/off cycles before it will post from a cold boot (and occasionally on a reboot). Sometimes I'll get the overclocking failed message and other times I'll boot right in to Windows without problem.

I'm running an E6850 G0 and Mushkin XP2-6400 4Gb (2x2Gb).

I'll try running the ram at 1066MHz and see what happens.
