Phenom 9850 Black Edition on NEWEGG!

[SocketMan]

My 9500 also died on the first day in that mobo. DFI support says tools like Sandra/Speedfan can cause the bios to be corrupted, which results in C1 errors.
I got the bios working again with an BE2400 and had no problems with an 9600BE and an 9850BE so far, but the 9500 did not yet post and i tried three different boards. As C1 errors are memory related i guess it's the IMC on the cpu whom stopped working.
I'd recommend bios versions 130/307 or 331 on the DFI M2A and be carefull with those low IO accesing tools like Sandra/Speefan/Evereset. Best is to run only one of those at a time.

Can you take the 9500 back for exchange? Should have the 3 year warranty.
Maybe try that "freezing" method KTE used to "revive" his phenom.

They sell this "dustbuster" which is Compressed air in cans) in North America,which blows C02 (I think)under high pressure,to get the dust out of togh to reach places,anyway if you flip the can and blow it you'll get a -50C "freeze".If it sells in Europe maybe you could try it?
