Hi

I have an ML 350 Gen 10 server (Xeon 3106 @ 1.7GHz with 16GB of ECC RAM). I decide to upgrade to 48 GB of Memory RAM (add 2 modules of 16 GB). according to HPE memory occupation guide i must use Dimm slot 8,10,12 .
my problem is the system recognise memory module but do not use RAM module that sitted in dimm 10.

How do you know this?

If you swap the DIMMs around - does the issue stay with the slot?
