definitely a bios issue with blend and memtest.

i tried testing my supertalents at 4-4-4-12 @ 420 mhz and i couldn't do blend or memtest (dos version). i tried every combination of voltages known to man.

then i tested the mem on my p5b... at 2.25 volts i can do 4-4-4-10 @ 475 with no errors for 24/7 use.

it has to be the bios... i think above 400 mhz the NB timings might be super tight... hopefully a bios update will fix it...
