I think you're also on overclockers.net. I solved it somehow by raising VDDG to 1.050v I used to run it at 0.950v long time ago without issues but every bios update changes stuff. ran it on 1.0v for a while without issues on A40 and A50 bios. but now it needs more... Might be related to this posting saying internal latency dropped. Maybe internally something is more voltage demanding because of that. Who knows... EDIT: I just checked my MSI webtickets and they had responded with the same suggestion to adjust VDDG. You can try something higher. For me it's 1.050v that does the trick.
