After 30 minutes, put it all back, booted into BIOS, loaded optimized defaults, rebooted ok, then shut down and installed the Q9550.... got error 8.7 again. @#!#$*&!!!!
Now off to figure out how to RMA this board. Any clues there?
Lvcoyote... I think you are right. If I can't RMA this one or it's too painful, I am already looking at one of the Gigabyte P45 boards to get me out of this mess.
I see that you were running an E6750.
How old is your board?
Does the BIOS chip have a silver label or is it a chip with no label with the numbers stamped upon the surface.
Taking some notes.
Report back.
