Trying to google about how well the unofficial support works, I get lot of hits about people saying that yes, it works, without any proof. I don't see people with a test DIMMs known to produce single bit errors making sure the unofficial support works, or making sure it works in every CPU or at least gives some easy to see error somewhere if it doesn't (I'm sure someone somewhere has tested something, but it gets lost in the noise. Anecdotes are only useful if there's enough of them to be statistically significant).

I really like what AMD is doing with CPUs, but unofficial ECC support just annoys me. It's supposed to give me peace of mind and eliminate one source of random problems. "Unofficial" really doesn't work great with that goal.
