overclocking a qx6700

has anyone done this??? i have a qx6700 on a d975xbx2 with regular CPU cooling (intel original fan / heatsink), i´d like to overclock it but have no idea about it and havent found anyone who has done it, could you explain it to me?? they say that you can get some 3.6Mz doing it, so i wanna give it a try not damaging the rest of the components.

thnx

i mean would i notice any diference in rendering times?? any which is worth the whole “overclocking” thing…
