ASUS Motherboards

I have a P5Q-E Motherboard and a Q9650 Core 2 Quad Extreme, and having no knowledge of how to over-clock my CPU does anyone have a link to the drivers because the disc that comes with the board is for 32-bit Vista operating Systems. Or of anyone knows how to over-clock the CPU/has done it on the this specific board and could give me some help on how to over-clock it, and I'm not trying to do an all out over-clock that could fry my system. I just want to do an over-clock that will take me from the 3.16 to about a 3.5-4.0.
