A pair of 1866MHz CL9 RAM modules* runs only as 1333MHz CL9 on 16h AM1I-A with coreboot is installed, but worked faster when a proprietary UEFI was installed. To fix this "turtle RAM" coreboot problem I tried to play with buildOpts.c - https://review.coreboot.org/c/coreboot/+/33920 , but the things like "#define BLDCFG_MEMORY_CLOCK_SELECT DDR1866_FREQUENCY" sadly did not help.
Any ideas how to improve the RAM speeds? How I can force this RAM to run faster?
Maybe AGESA debugging / IDS tracing is of some assistance? I have not tried it for a while, though.
