What else do I need to adjust? The FSB is proven stable at 400mhz with a lower multiplier, so the NB and SB should be fine.....or is that not how it works...?
9x400 != 8x400 for N/B! It can be that the N/B voltage should be raised. What are the other settings? ( pll, fsb termination, pcie/cpu spread spectrum, transaction booster, load line callibration ). How much is the vcore drop?
