thank you all for your help, but i might go with the msi. still have 14 days to decide if i want to do the rma. do you know why the high pitch sound? i really the dfi board. i had dfi lan party boards in the past withing the nf4. i switched to foxconn for the 590 and now i'm going back to dfi for the 790fx. if not for the annoying sound, this board is pretty sweet.
