I had 4gb ram on a old desktop pc, I just installed 4gb extra ram. Bios detects 8gb, windows detects it. But linux only sees 4gb.
Linux appie-imedia-S2185 5.4.0-70-generic #78-Ubuntu SMP Fri Mar 19 13:29:52 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
total used free shared buff/cache available Mem: 3365 1278 806 100 1280 1753 Swap: 3514 0 3514
cat /proc/meminfo | grep -i memtotal
MemTotal: 3446176 kB
But then lshw notice there is 8gb:
lshw -short | grep ‘System Memory’:
/0/14 memory 8GiB System Memory
Since Bios, Windows and lshw sees the 8gb, the problem should be with linux…. Anyone any clue on how to make linux see and use all my ram?
