Went back to 0802.... 0901 didnt seem stable to me after running it for a bit, passed memtest/Prime95 but something didnt seem right about it. Would get random booting issues, vista wouldnt load sometimes, would lose RAM settings in this order .... failed OC type no boot (DETDRAM) then turn off ----- power on, power off (to change settings to something bootable) and after the first double boot it does on a failed OC it resets again, and I have to use a cheap stick of DDR2 to boot again.
