The RAM passes Memtest86+ v4.0. I know it is strange.

It might have to be trial-and-error then to work out which stick(s) is/are
faulty, but you might want to give memtest86 a look.

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.
