just install p4 3.0e abit vt7 (via pt880) cheap board, my advice is, don't try it. maybe this board is meant for lower end market n i should not use a 3.0e on it. now swich to gigabyte 848 board (still consider cheap board, but w/ gigabit lan), then okay, stable liao. but then, don't use prescott in a office environment, stock fan sound like there is a motobike in your office, with engine on.
