Kinda late now, but did you try installing with just two sticks of memory?

I seem to recall something a while back about Vista not playing nice during the install with 8 gig, but that once installed using 4 gig, the other 4 can be put in without any problems.

Yeah, I pretty well tried everything. I installed yesterday with 2GB and then reinstalled today with 8GB just to see and I had no problems installing with 8GB.

That CPU Margin Enhancement that they added in the recent BIOS's doesn't seem to like certian processors. It gave me a lot of grief last week, I had to go back to 0803.

Damn, this is one picky board. I may go back to 0803 also just to see if it helps with the OC.
