That would be the problem. Your board doesn't support any Phenom II.
The 940BE is an Athlon X3 turned into an X4 IIRC. I think you have the "core unlock" on and you had the bad luck to get one with a defective core for real.
Turn that thing off and boot again.
The PhII 940BE was not an Athlon X3. It was actually one of if not the first PhII to come out. It is an AM2+ chip. The Athlon x3's were AM3 and lack an L3 cache making them inferior to an Phenom II 9xx. Some of the PhII 8xx chips were higher clocked and rebranded Athlon II's.
