PCI-E Frequency from 100 Mhz to 101.

I ahve heard before that this shall have solved stability issues since the ASUS P5B series, but it never did for me. Anyway, for those who are suffering prime issues, enable this for a test and let us know what it does for you. I know it doesn't sound very plausable, but it is entirely possible that this is changing a strap within your intel chipset that makes it all stable.

This applies most likely to all Intel chipsets and ASUS boards since the P965 chipsets. For example, P965, X975, P31/33/35, X38, X48, P45, etc.
Very interesting. Thanks for sharing this. So...changing the PCI-E frequency will change a strap? I'm not very knowlegable about this frequency. I will definataly give this a try though. I am still searching for the answer as to why I am BurnTest and Prime stable at 400 MHz but become Prime unstable with only a small increase in FSB to 425 MHz. (This is only 25 MHz above default on the FSB). No one else seems to have had any solid advice regarding the IBT/Prime discrepancy that several others have been experiencing as well.
