I cannot get the node to startup to the point where OMSA runs. It freezes on
startup with the bad RAM.

Are you running OMSA? It usually is able to pinpoint which stick is the
cause of single bit errors. It can be helpful to stress the RAM with some
heavy compiles/DMA to make the bad stick throw an SBE sooner.
