Hey all! I've recently started overclocking my cpu but I'm afraid to go on, as I cannot find the "PCI Clock Synchronization" option and am thus afraid of damaging my cards. I've updated my BIOS, but still cannot locate it. Anyone able to help me out?
I have a Q9550 if that is of any importance.

Thanks in advance.

Im not sure what that is and why is it needed to overclock...sorry. Is that the same as the PCIe bus (100Mhz) that you want to lock?

I read it here http://www.overclockers.com/forums/showthread.php?t=515316.

"PCI Clock Synchronization - Use 33.33 MHz here. Again, if you leave the setting on auto, the PCI clock will creep up proportionally with your FSB which can damage cards you may have there aren't designed to run at higher frequencies."

Oh wow...heh... dont worry about that. Most newer boards, like you have now, already have those locked.

That advice is from back in the day when boards actually had that option.

Like ED mentioned, the option in your BIOS is called PCI Express Frequency (Mhz). It's located on the MB Intelligent Tweaker(M.I.T.) screen, and when set to Auto adjusts the PCIe clock frequency to the standard 100MHz. The BIOS also gives you the option of manually changing the frequency, w/ the adjustable range from 90 - 150MHz.
