I had a K6/2 with ECC back in the late 90's. So, yes.

But for whatever reason, AMD never seems to put ECC in the bullet lists for why you should buy their parts. I guess as someone else mentioned its because the motherboard manufactures don't enable/qualify it even though its likely just a matter of firmware tweaks ever since the DRAM controller moved on chip. I got it working on a cheap phenom II/gigabyte motherboard (IIRC) some time ago as well. In that case I don't think the motherboard even advertised it, but I had some unbuffered ECC DIMMs lying around and I plugged them in, and they worked. Of course the only real indication besides booting the machine that it was actually working was a kernel blurb during boot about it. I don't think I got the EDAC reporting to give me soft error rates at the time.
