Hi Kerry, first of all: thanks for your effort! While I had no success at first, I now can get to the boot prompt (haven't tried any further yet). Anyway, I currently have 2 DIMMs, each 4 GiB. A dual-channel configuration does not seem to work, the DIMMs are detected, but coreboot throws an "ASSERTION FAILED" error (see attached log cb_h8scm_01.log). It seems to fail because it somehow seems to think no DIMM is found (despite both DIMMs being detected). I tried disabling this check, but this only leads to a reset. The same problem exists with a single-DIMM configuration. However, when I switch to a dual-DIMM, single-channel config, it at first does not start at all (i.e. no output on serial and no heartbeat from the BMC) - but when I trigger a manual reset it immediately starts up (see attached log cb_h8scm_dimma1a2_success.log). I'll report back when I find out more.
