i recently made the move to PCI-E, which involved me changing my mobo and graphics card, the old mobo was a neo2 platinum and it had no problems running my a64 3200+ at 2.5ghz. it was rock solid and never crashed, but now with this new mobo (epox 9NPA+ Ultra) it will happily run on 2.5ghz...until you stress it, then all i get is constant lockups 
this might be due to the amount of extra memory options this mobo has, ive never even heard of half of them and i've been overclocking for 6+ years so i have no idea what to set a lot of them to 
, so far i have tried upping vcore, upping memory voltage, relaxing memory timings and ive updated the bios. it is superpi stable and can get through 3dmark05 etc fine, its just when you have it under load for over 10 mins it cant seem to handle anyone have a suggestion?
