You have to use buffered memory with an opteron (well the socket 940
ones at least), and unbuffered with an athlon 64 (socket 754/939/AM2).
I believe you can use ECC memory on many boards, but it depends if the
board supports it I guess.  I have never bothered with ECC memory, and
so far things have been stable enough that I have no idea if it would
have ever helped with any crash I have ever seen.  Most have had
perfectly good explanations so far which did not have to do with RAM.
