I have the same batch. Try 400 for your fsb
1.425 for the vcore
set your mem multiplier to 1:1 however that is on your board
question: that nforce board may never see 400 fsb... increase the fsb voltage. Under chipset voltage add another setting or two...
Watch youe temps, but at 1.425 you should see stability, if not, notch it up a bit...
Havent tried 1:1 Yet.
