Re: MCE: Does this look possibly like a slot issue?

Hey Larry,

 It is possible it's the motherboard itself, but it's rare. The way I
would determine this is to swap the DIMM module with another
populated slot on the motherboard and see if the error migrated
to the new slot or not. Also, this error doesn't necessarily mean
there is a problem that needs to be addressed. If you have been
running the system for many months and you see ECC errors a
handful of times, it can probably be safely ignored.

Best regards,
Richard Gallamore
