I cannot find the thread now, but there were some threads concerning
the performance of X2 duals a while back. Basically, what people
discovered, is one core is a much better overclocker than the other,
which didn't make a lot of sense. In one case, the processor was
barely stable at stock speeds.
Then someone decided to remove the IHS from the top of the processor.
I'm including this thread, as it has a picture of the inside of the
processor. I cannot remember which site did the original investigation
of the uneven performance of duals.

The other picture I saw of a dissected core, showed a thermal interface
material that was a lot more granular. The theory was, that local
overheating (just a portion of the die) could happen. One guy
went from having a crappy dual core (one core pretty bad), to being
able to run both at 2.7GHz stable, when the IHS was removed.
I would suggest contacting AMD and getting an RMA. 80C sounds like
a pretty big jump, so it could be a problem with that grey stuff.
