I don't see anything nonsense there? Your FBDimms are just running too hot, like everybody else's (excluding mine :P: ) which means they'll throttle a bit.
Reason why your (and many other) boards is still alive is because you don't crunch on it 24/7/365. There is a design flaw in the VRM circuitery that kills these boards when running 24/7 loaded, whether they are overclocked or not. If you run them idling all the time the board will last through its 2 year warranty span and THEN die.
