So, I ran some stability tests. Q9650 480fsb 8.5 multi, M2F board, DDR2 1000 @ 960 = 4080mhz Vista 64 U (2x2gb)
Memtest passes twice. I understand memtest isn't exactly 100% ....Tried IBT 1.9 and it failed off the bat. I reset my bios; everything to default and IBT failed again. Y- reports, 1-max stress, 5 itterations = fails

Any idea what it is? Currently running Prime95 Large FFT's and its fine the past 45min
