This is pointing to something which is powered from 5VSB voltage. It could be
some GPIO settings which sets voltage for ram through some other chip. It could
be some powersequencing pin connected as GPIO too, it could be a i2c bus
multiplexer operated by some GPIO pin too ;)
I would suggest to dump the superio chip with "isadump" (all logical devices)
and all registers powered from the 5VSB well if known. Check for changes on GPIO
pins or SuperIO global config.
Check if the fail is caused by missing SPD EPROMS (error SMBus reads) or just by
It could be also something from the SB itself, but try with superio first.
Then compare the dumps with that you obtained from coreboot (you will need to
program that) You can check from linux with legacy bios, then boot with coreboot
and then boot with power unplugged.
