No, what you need to see is a) whether what you did was valid (for the
Supermicro m/b on the server I'm working on right now, the manual says the
a-banks must *ALWAYS* be populated...), and b) you might find some
troubleshooting info to help you identify which DIMMs are the problem.

Nope. From your original post:

So with 2 4-core Xeons, I don't understand how you can get 3x and 5x.
Could you post some raw messages, either from /var/log/message or from
/var/log/mcelog?
