After doing this, should I redo flashing the BIOS you sent? Meaning, should I re-flash another fresh empty-MRC BIOS and then power on with this new memory stick arrangement? My assumption is probably not.

I'll do this. Just wondering, is this so we can see what data gets written to the MRC section with an alternative arrangement of memory sticks? Or is it just to test for any bad memory slots / bad RAM sticks?
