P5B Deluxe: BIOS screens for maximum overclocking success

[Rex_foxhound]

Hello everybody. 1st time poster here.

I'd like to thank all the people that have put this sticky together. Its been a life saver.

Anyways... I have one question:

On the PCI-E frequency, I'm at 120 now. How much higher can I go and still be safe?

The reason I'm asking is with my 7900GS @ 630/869 and default CPU settings, my 3dMark05 score is 10,316.
When I follow the guides in this sticky about overclocking the cpu and set the PCI-E freq. to 100 and have the same exact gpu clocks, ny 3dMark score is significantly lower (9,000 or so).

when I bump up the PCI-E freq. to 120, my score goes back up to 10,715.

I'm wondering if I've done something wrong or what?

here's a screenshot:

This is using all stock cooling too.

Any advice or help is appreciated.
