Have you seen my stability? I cant seem to find it..

ive been messing with my oc setup for some time now, and im having the darndest time getting my rig stable. check the sig for my specs.
i just switched from a p4c800 deluxe to the max 3 last week, but things dont seem any more stable to me yet. my 3.0c is a 30 cap SLKWU, and the highest ive pushed it was 3.9, but nothing is really at all stable past 3.2 - 3.4.
what bothers me is, that at 233 fsb 1:1, with my memory at its correct rated speeds, prime failed after 3-4 minutes. that shouldnt be happening. i plan on getting some new parts to mess with, like new cooling (currently using stock) and a pc power&cooling 510 dlx. my goal is 250 fsb with no stability issues at all. help me, and share your advice on how to reach my goal

Here are a couple links to help you figure out the mobo settings.
