AMD64 3500 with stock hsf. figured I kill two birds with one stone and try some minor ocing then test with prime to heat the core up and swap the stock HSF for a Zalman. I have a gig of ram, how much should a I dedicate to prime to get a decent run and heat up my core enough to cleanly remove the HS? I've heard half or more on blend is pretty effective, but I would like some advice. thanks for any replies.
