Such a shame about Asus' RMA, their products are awesome. Until they break obviously.
I remember back in 2003/2004 I had an AthlonXP board that was the wrong rev to support the newer Barton chips, their documentation said it supported it but negelected to state the rev. Had a right old battle with them, the reseller didn't want to know (they are also still terrible, not OcUK but main competitor) and Asus themselves took 2 months to understand what the problem was and sort the board out. They never did update their documentation either.
