if you wanted OC should take a INTEL

must also see if power supply can cash O/C ?
otherwise you go in bios and you gradually increase the FSB (formerly deactivates you options for energy savings C1E, SpeedStep ...) all this by controlling the temperature of the CPU (prevents the cores exceeds 75 ° C).
