WHy would you use the FSB when you have the multi? Much easier to OC on the multi.
OP, turn auto voltage off immediately! You'll fry your chip!
Set it to "normal" or whatever they call it, and increase it a couple of bumps at a time. Use the Multi to OC, Since you dont know enough about OCIng yet to use the FSB, which also does the ram. If you only want 4ghz, turn off Auto volts, and the turbo feature, along with the power saving features. (Just for testing purposes) you can turn the power features on again later. So start with stock volts to see how high you can go, once you BSOD, up the voltages slightly till you pass atleast 6 hours of Prime 95
