i believe u can, but at d expense of having lower ram freq & mebe imc freq. since it's a locked chip u can only play with htt oc. if u have no plan to use lower cpu multi then htt should be @ 243, with 1600 ram divider that will take ya ram near to 2000MHz, something i think might be a bit challengin for d board & d ram. i mite be wrong thou.
