Samsung "M393B5270CH0-CH9" nor SK Hynix "HMT151R7BFR4C-H9" work with
the Coreboot 4.9; I'm not sure on a specific error message; the
motherboard just didn't POST with those sticks.
The SK Hynix "HMT151R7BFR4C-H9" sticks worked with Libreboot 20160907
however.

There were limited information regarding memory compatibility with KCMA-D8.
On the other hand, there were more information for KGPE-D16 regarding memory
compatibility, and it seems the good RDIMM sticks for that board are mostly
from either Micron or Kingston. There are few entries about
Ok, it seems that there are some general issues with the RAM compability.
Libreboot seems to have some code that has less issues with some RAM sticks,
but the stability has yet to be confirmed. For example, I discovered a scenario
where the size of the RAM was detected incorrectly. The question
I planned to test coreboot on this board as well, and I'm having the same
problem (compiled from latest source).
The sticks I currently have are 16GB VLP ones. I've some M392B2G70DM0-YK0, and
a few HMT42GR7AFR4A-PB. None worked with this board using coreboot, giving out
similar "DIMM training
To avoid having to run a libreboot / ancient version of libreboot,
there is a need for commit dichotomy to find out which commit broke
the things - and, if you would like it to happen faster, you'll have
to do it by yourself. It shouldn't take too much time: even if you'd
start with the ancient
Hi,
I was using four (and later eight) Crucial CT51272BD160BJ (4GB, ECC,
unbuffered) for more than a year (with coreboot 4.7 if I remember
correctly) with two Opteron 4284. The only issue I have found is that
the memory is running at DDR3-1333 instead of DDR3-1600.
Cheers,

The proprietary BIOS and Libreboot are working well. Also a RAM module that is

Hi guys,
thank you for the valuable feedbacks. As I can see from the git commits, it was
mainly Timothy Pearson from Raptor Engineering Inc who worked on the kcma-d8
porting. Libreboot is based on some version of coreboot 4.6. But it seems that
after that a number of RAM related commits has
> Why libreboot works and coreboot doesn't?
Libreboot is some older version of coreboot where all the blobs have
been removed. If something works at libreboot but doesn't work at
coreboot, most likely that means there was a breaking commit at
coreboot which came later than a libreboot release
For non-ECC modules on the KCMA-D8, I found that Samsung M378B5273CH0-
CK0, Micron 16JTF25664AZ-1G4F1, and Nanya NT2GC64B88B0NF-CG work with
Coreboot.
I also had SK Hynix HMT151R7BFR4C-H9 which didn't work with Coreboot,
but worked on Libreboot. Samsung M393B5270CH0-CH9 also doesn't work
