Are you using a programe or a using the BIOs to overclock?

From what it seems from some research is that it is becuase i can not lock my pci bus at its normal speed stupid gigabyte need sort there bios out any other way of locking it or am i going have to overclock from windows

I had this problem when I overclocked my brothers k8nxp sli. The 'Over CPU clock Right Now!!' bit is normal and IS shown when you have a stable overclock during POSTing before windows boots. The reason it keeps rebooting is because it is NOT a stable overclock. I suggest going right back to square 1 and finding your rigs max HTT by underclocking the cpu and ram, then find your max cpu freq, then max ram overclock to try and establish your weakest link. Make sure you have the most up to date BIOS installed and I think that there are extra options in there but you have to press ctrl & F1 (?i think)

I have the same motherboard as you with an XP3800 X2 in it, can't get over 2.2GHz. I've tried all the things mentioned and have come to the conclusion that it is probably the passive chipset cooling as it is running at around 70C, a fan blowing over it could well help.

One thing that worked marginally for me was to change the PCI-E speed to 101 (I think it was that one, I'll check tonight). This allowed me an extra 100MHz... :eek:
