P4s and their chipsets are really picky about installing INF and chipset patches as soon as the os is installed, in fact somewhere on their site is an actual list of what to install in what specific order. I'm not sure if it's such a big deal now as it was when the first s423 P4s came out. I do know there really is a performance hit if you don't do it right tho. I wonder why? :-?
