Every time I change anything, it fails to post. Even if everything is stock and it has nothing to do with overclocking...
Is this after you flashed to new BIOS or just any change to BIOS settings? Seems strange, but I always set to default settings (F5) before flashing BIOS. I use ASUS EZ-Flash 2. That is the best way to flash BIOS IMO.

Strange thing happened today though. I have my two HD4870x2's in X-fire and when I went to new Catalyst drivers 10.5, I had strange artifacting and then reboot. I did not change voltage in PCI-E after flashing to new 0704 BIOS. I had to remove one video card and remove drivers via hardware device. I then was able to reload new 10.5 drivers and everything is okay. But question is which PCI-E voltage do I change? Southbridge or Northbridge?
