IIRC just because it boots with ECC ram doesn't mean it is actually error correcting. I'm under the impression Intel spends considerable amount of money to prove their memory controllers actually error correct & historically AMD hasn't spent the money on documenting theirs.

Back when high-end supercomputers used AMD Opterons, systems with a lot of memory would have had observable problems had ECC not worked pretty well.

Right now the #3 system in the world is a Cray system using Opterons.

ECC is not complex to implement.
