PCI-E Frequency Problem

post #1 of 2
Thread Starter 
I'm using an ASRock Conroe-DDR667 mobo and an e6750 c2d. When I go into the BIOS to OC, I can either let the BIOS keep the PCI-E in sync with the processor OC, or set it to async.

Problem is, with async I still have to step up the PCI-E frequency with the processor OC or the machine won't boot (thank god for boot guard). I got as high as a 364 processor OC (from 333 originally) and 120 PCI-E, but if I go any higher on the processor OC it won't boot unless I go to 121 on the PCI-E frequency (which I can't do because then my SATA drives vanish).

I've heard that running a PCI-E frequency over 118 was dangerous, but my machine boots and I don't seem to be getting any errors (and Crysis defaulted to VERY HIGH on everything and was actually playable).

I'm using a XFX 8800gt Alpha Dog and it's a PCI-E 2.0 card. Does the 2.0 spec allow for a higher operating PCI-E frequency?

Sorry for the n00b question....you may now throw your bananna peels at the n00b.

over 120-125 can be bad, i dont think being pci e 2.0 matters. its a 945 chipset these board need the higher pci e clocks but to overclock. if you can get a p965 chipset or newer, that will let you get much higher than 360fsb, the dfi dark is a pretty cheap board now adays.
