To answer my question myself: It works partially.
1.) Samsung M393B1K70DH0-YK0
Type: DDR3 DIMM 240-Pin, reg ECC ? Ranks/Banks: dual rank, x4 ? Modules: 1x 8GB ? JEDEC: PC3L-12800R ? Voltage: 1.35V
I got 8 of these working with one CPU package on the KGPE-D16 with one of the latest Coreboot master versions:
(Please note, that coreboot is officially spelled all lowercase.)
How much did you pay for these modules?
One of them costs around 12-25 Euros (used) or ~65 Euros (new).
Just to be sure. You got 64 GB of RAM working. If you plug in more modules, it fails, right?
No. Using 64 GB worked more or less fine, but using *less* than 64 GB caused issues - depending in which slots I had put them.
Version: 4.5-963-gf57a768
Please upload your logs to the board status repository. (This commit has not been uploaded by REACTS, so it wouldn?t overwrite anything.)
I uploaded one of the tested configurations here:
https://review.coreboot.org/cgit/board-status.git/commit/asus/kgpe-d16/4.5-9...
I was not able to upload more configurations since the build_status output folder is named after the build, and I didn't want to rename too much manually.
Without the logs, it?s hard to debug anything. Verbose logs are one of the biggest advantages of coreboot. So please upload them, or attach them.
I attached the serial logs of one of the failing configurations (all orange slots populated).
However, I was unable to reproduce the exact failure because meanwhile I populated the second CPU socket and didn't find a way to deactivate the CPU (after pulling the second power connector the system did not boot up at all).
I also noticed the following messages in dmesg:
[ 1561.833618] [Hardware Error]: Corrected error, no action required.

I didn't notice any of these before the installation of the second CPU module. Don't know if this is related or not. But I'll run a memtest next to check if maybe one of the modules could be faulty.
Cheers, Daniel
