causes no operable memory.
02h = Memory DIMMs on all channels of all sockets are disabled due
to hardware memtest error.
3h = No memory installed. All channels are disabled.

Memory test failure
01h = Software memtest failure.
02h = Hardware memtest failed.
03h = Hardware Memtest failure in Lockstep Channel mode requiring
a channel to be disabled. This is a fatal error which requires a reset
and calling MRC with a different RAS mode to retry.
