I just put together a new box with this mobo and damn is it solid. Im running at 3.0ghz with my Q6600 with literally no effort (backing off a ram ration and increasing the fsb, no voltage increments at all). I've never had this good an experience overclocking, but then again Ive never used the higher end components I did this time. Thanks everyone for the bios info though, Im leaving my mobo at 0303 for now, it seems to be working fine and I dont want to run into issues.... yet...
