What stepping opteron do you have? I currently have this board, an opteron 170 at 2.6ghz, with Vcore 1.5v, 2GBHZ G.SKILL memory and prime is failing on core 0 in < 2 minutes.
I had it 2+ hours prime stable at this voltage at 2.5ghz, but when I upped the HTT to 260 (x10 multiplier), it is not stable at all.
Cooling is SI-120 w/ 120mm delta fan, and temps are idle ~32C-33C, load before prime fails is 43-44C, so that seems fine...I just can't figure out why it's failing so quick at 2.6ghz. Any thoughts?
dont know if you fixed your proiblem. but to test if its your memory that grapping out on you @ 260 then lower your CPU mult 2 ticks. this will take your CPU out of the equation. then run memtest86.
