What Phenom is it? It's not one of the very early ones with the cache bug is
it? If so, do you have the bios update? (If the model number ends with 50
then it should be ok.)

I've seen memory fail after several hours of memtesting, fixing it did fix
the occasional random crashes. (With the pvr, but was with myTheatre before
I moved to myth.)
Memory is funny stuff when it starts to go wrong.
Also, myth is the kind of workload that does tend to stress memory, so that
might explain it.
