i just replaced my 1x512 pc3200 ram with 2x256 buffalo pc3700 bh-5 ram and i get no errors in memtest86 with stock vcore and 2.8vdimm but once i up my vcore i get errors at the last 2% of test 5 at any fsb. i had no problems in memtest86 with my old ram and high vcore, what could be the problem? are there any bios settings that can fix this? anybody else have this problem before? if i can't fix this problem, i'm stuck at only overclocking the memory. i'm at 5x211 right now just to be safe, i got into windows at 211x11 at stock vcore(1.5volts) but it freezes 5 minutes into doing anything, so i need more vcore to make it stable. by the way, i have a biostar m7ncd pro.
