I have my system clocked to 504 (4.5x112). And it's stable but if I increase the bus speed to 124MHz it's not so. So people are telling me decrease the voltage to 2.2 or 2.0 volts; even though I have an ASUS P2B-F, and it only provides .5v increments. Well then what speed do you set the but at? I thought anything over 124MHz would be damaging. How do you get 558 from 450 using 2.2/2.0 volts?

Please explain I'm confused.
