thanks for all the input guys, unfortunately i cant test my new quad until i get my new mobo, im upgrading from a 680i to 780i from evga, i enjoyed clocking my e6600, ran 24/7 @3.6ghz voltage of i.525 set in bios, could have done the pencil mod, but was a bit scared to do so, most i done was thermal paste replacement on the nb/sb chipsets and mosfets.
