Im surprised as to how much ive learned about overclocking an A64 without even owning one. www.ocforums.com
is the place to go about overclocking, lots of good info there. There are Mushkin, OCZ, Newegg representatives there incase you need to PM them or something. They are very very nice. BUT OF COURSE IM NOT SAYING DITCH THIS PLACE FOR THAT
im just saying, that place is loaded with info about overclocking. Check it out sometime.
