Hi Sean, libreboot is always behind coreboot regarding
the commits, so
RAM compatibility could vary because of some breaking commit that
happened after the latest libreboot release but before the latest
coreboot. So of course it would break at the next libreboot release as
well. You could prevent this by searching for this commit using
dichotomy method (e.g. just 10 tries to find at the range of 2^10 =
1024 commits) and tell us if you'd find it
I ran into the same issue, and I'd like to find the coreboot commit
which introduces these problems.
My RAM is: Hynix HMT31GR7CFR4A-PB (8 GB 2Rx4 PC3L-12800R). I just now
realized that it's low power DIMMs, but it boots fine with libreboot,
so that shouldn't be a problem.
A have two DIMMs installed in the slots A2 and B2 (according to the
manual), with one Opteron 4332HE installed.
I managed to build an older coreboot revision around the time of the
last libreboot release (which boots fine for me), but unfortunately it
doesn't output anything on VGA / serial.
I might make a few more tries tonight, or in some weeks when I have
access to the machine again.
For the record I attached the serial log when booting with current
master; apparently there's a failure during DIMM training...
