I have a System Centos 7 has been running with 768GB of Ram for a couple of years now . added 512 GB ram to bring itthe 1.25 TB of ram.
Installed it no problem , the Mother sees it , lshw sees it , However the OS is only reporting using 1TB of ram
I'm sure it is something simple I'm missing. But I can't figure it out
