Server memory problems

Test the new memory by itself, keeping at or below the 64 GB
you know works. Then you will know if the board is happy with the
new memory or not.

If the mainboard supported configurations allow, test all slots
while keeping <= 64 GB. If there is a bad slot, visually inspect for
cold solder joints, shorts, etc.

IIRC, FreeBSD has some knob that allows limiting the memory used.
Try having > 64GB of memory plugged in, but limit how much
you actually use.

Some systems are very very picky about memory. Published required
specs for memory might not cover everything. The technical support
folks might have learned more what actually works or not.
