Ok, I have an Asus P4C800-E Deluxe and I just went into the BIOS and did a 5% overclock. I never OC'ed a cpu before but I do have some basic understanding of how it works (very basic). I'm trying to get my P4 3.4ghz up to 4ghz. What software can I use to test the stability of my OC? Right now I have CPU-Z.
