OCing on my P5B-E, and when I raise the PCI express bus in BIOS over 100, my pc boots into windows fine, but the internet connection stops. When I reset back to 100, everything is fine again. Trying to get to 120 stable.
Doctor, Doctor...it hurts when I do this...
STOP DOING THAT!
If you raise the PCI-E clock and something stopped working....what should that tell you? EVERYONE leaves the PCI-E clock at 100. Just because there's an adjustment for it doesn't mean you need to go mucking with it.
