I have a Q6600 on an eVGA 680i board and I want to overclock it to at least 2.8-3 Ghz. I read the nvidia overclocking pdf manual which basically says to disable all of the power saving options and things like that. The only thing it doesn't mention is setting the PCI express frequency to 100 MHz. I know that I did this on my P35 board, and I wanted to know if I should also do this on the 680i board. I would think I should, but no mention was made in the manual so I wanted to double check.
