Im using Kingston hyper 6400 4-4-4-12 2gb Modules X 2

I am having trouble running the rams at 400 FSB 1:1 Ratio.. im sure it can reach that speed 3.6 ghz with 400fsb 1:1, im just not sure how to set the motherboard settings.. so i leave most of the options on auto.

Any gurus know wat settings to put into ai tweaker in asus p5q pro for a 400mhz 1:1 overclock?

sure i bet most of them are ocing i7.. that will be my next step.. im just squeezing everything out of this processor b4 i move on.. ITS STILL KINDA SOON TO MOVE ON to a new processor.. unless money is no object to u..
