Is it safe or necessary to raise the NB and SB voltage if you are going for a higher FSB instead of multiplier ? I am at 15.5x with a 220 Fsb at 1.41 cpu volts. But if i go any higher with my Fsb even raising my cpu volts wont help. I like the Fsb cuz it also raises my memory Mhz too. Im at 440 Mhz with my OCZ DDR2 800. Any suggestions ?
