Whatever the cause, if Asus are in touch with AMD over these issues, we are going to see a lot of bios updates, before Asus removed all of the old bioses, they were releasing new bioses every 10 days.
Asus are replacing burnt out boards, but amd are not replacing the CPUs under warranty, they are blaming the end user for using expo, but at the end of the day, that's a cop out, it's still their fault.
I've got to get my water block off this weekend, I'm going to have a look at the socket and chip, and if there is any signs of bulging, it's going straight back to the shop I brought it from for a replacement.
