With the original 0001 BIOS there's a BSOD wit error code 0x00000124 at 4 hours running Prime95 Blend. This could be to low voltage or bad driver or bad hardware in Windows 7 Ultimate X64. The 0x00000124 BSOD is probably the same as the MACHINE_CHECK_EXCEPTION BSOD in Windows XP X64.

With the 0001 BIOS with updated option ROMs it doesn't BSOD at four hours but it gives me a rounding error at 4 hours in Prime95 in Windows 7 Ultimate X64. This happens a lot faster in Ubuntu 64 bit and happens on more than one core too.


What I'm trying to do know is up the NB Voltage to 1.31V in the BIOS or 1.28V real to try to have it stable for more than 4 hours Prme95 Blend in Windows 7 Ultimate X64 with the 0001 BIOS and the updated option ROMs. If I can run it stable for more than 4 hours I'll try it again in Ubuntu 64 bit to see if it's also stable with a little higher NB voltage and the 0001 BIOS with updated option ROMs.
Just an idea: try it with higher voltage for the memory. Even if the memory-test runs fine for hours, it looks like in Win7 X64 the memory needs more voltage with tREF 16120. In my case i got stability again with 0001-mod Bios, 1.14v VTT and NB 1.29v (Bios, 1.26-1.28v real), memory 1.86v instead of 1.84v.
