My MSI 770-G45 couldn't handle my Phenom II X4 overclocked to 3.8ghz at 1.5v. It died. I RMA'ed it, and the unit they sent me wouldn't wake up out of S3 sleep. Then to top it off, my wife spilled hot miso soup onto it. Now, the Asus P8P67 that I got to replace it won't let me install ram in slot 1 or 2, so I'm having to RMA it.
There you go.
