0903 is working for me... I took pics of the BIOS settings under 0901 and tried EXACT duplication under 0903 and it wouldn't boot into BIOS. Need a little more time, but as far as i can tell the only settings i changed were the spread spectrum and PCIE spred spectrum from auto to disabled... I'll report back when I get this stable like 0901, and take a few other pics of 0903 BIOS...
