to get higher fsb with stability its the Northbridge voltage that needs to be a little higher around 1.5volts for this should be ok but again watch the temps . 1.45volts on air is the max you should give your cpu , but with any Overclock there is an element of risk !!!!! if you cant afford to replace your cpu then dont push it i always thinkI had already disabled those features.
You were right on the voltage front though. 1.4v works fine. Looks like I was simply not giving the CPU enough juice.
Should I be attempting to raise the CPU voltage further than 1.4? Is this to allow me to increase the FSB, and if so, what's the best steps to hop up on on the FSB frequency?
