I use DDR1600, so i defined BLDCFG_MEMORY_BUS_FREQUENCY_LIMIT to
DDR1600_FREQUENCY.
Also a have #define BLDCFG_TIMING_MODE_SELECT TIMING_MODE_AUTO, so
coreboot automaticaly finds optimal memory clock. I can see it coreboot log:
MemClkFreq: 333 MHz;
MemClkFreq changed: 333 MHz -> 400 MHz;
MemClkFreq changed: 400 MHz -> 533 MHz;
MemClkFreq changed: 533 MHz -> 667 MHz;
MemClkFreq changed: 667 MHz -> 800 MHz

Hi, Константин
Did you try to change BLDCFG_MEMORY_BUS_FREQUENCY_LIMIT and
BLDCFG_MEMORY_CLOCK_SELECT in
src/mainboard/supermicro/h8qgi/buildOpts.c ?
BLDCFG_USE_HT_ASSIST can't be set as TRUE on h8qgi now. I am sorry but
I don't know how to debug this issue.
