Unbuffered and/or NOT registered.
The buffered/registered is cheaper on ebay, and also higher density (up to 32GB
or 64GB per DDR3 DIMM) so it could look like a bargain but it isn't.
It's cheaper because you can't use it on most consumer hardware.
AMD hardware that supports buffered and/or Registered ECC is Threadripper or
server processors (Opteron, Epyc).
Similar for Intel, only server-grade Xeons and Enthusiast i7 processors (Socket
2xxx or something) support that.
Buffered/Registered RAM exists for servers that need to use large amounts of
RAM, hundreds of GB or even a TB or more (for multi-CPU systems).

Hello,
This might be a dumb question, but not having a manual to go off of, would the
ECC ram have to be buffered or unbuffered? (if it can be made to work with the
AM1I-A at all) Any other important specifications?
I bought a AM1I-A (I've had my eye on a good deal on ebay) and it should be
here in a couple of weeks.
Sincerely,

Hello,
That has short but very informative indeed. Thank you. :)
Even if the pinout is the same, is it possible that some connections have been
left disconnected or components unpopulated on the board, which would prevent
ECC from working?
As a more general porting question, what steps should be taken in porting
coreboot to the larger board (the 'M' variant) to avoid unpleasant consequences?
I would think the PCI layout would be different (obvious, since one board has
more slots then the other) but what should not be assumed to be the same?
Thanks,
-Matt
