Quick go with the Asus overclocking tool heralds 3.6Ghz with all settings on auto and a 1:1 with the memory. The program decided I needed 1.32V and with Prime95 running RealTemp reports 46 degrees - not too bad I suppose.
One question though, my RAM is rated 1000Mhz; do you think it would be possible to retain a 1:1 ratio and increase the FSB whilst remaining within the boundaries of the CPU voltage range AND keep it stable?
