also what motherboard do you have?
For 4.5/4.6 you may get away with just (to begin with) leaving all settings on auto, go into the bios, leave the blck at 100 and set the multiplier to 45/46. Then boot into windows and fire up coretemp (for VID) CPU-z (for vcore) and P95/IBT (for stress). And see what VID and vcore the auto voltages set out.
