I have installed a Ubuntu Server 16.04 amd64 on my machine. I'm having trouble with ram capacity - first I installed a 2GB stick which
free -m reported as
1430 total size, now I installed a different 4GB stick which is now reported as
3380 in size, see below:
x@x-server:~$ free -m total used free shared buff/cache available Mem: 3381 890 2022 14 468 2435 Swap: 1467 0 1467
It is a considerable amount of missing memory (~20%) - what could be the cause of this?
I'm using an ASUS AM1M-A board.
Both sticks have been used in other machines and are functioning properly.
