I have just installed Linux Mint about 5 days ago, and then I have upgraded my RAM memory from 8 GB to 12 GB, and I have 4 GB more on the way, so it will get to 16 GB or RAM.
The only thing is, I don't understand how the
free -g command works.
Here's a picture of Stacer, in which I can see my RAM up to 12 GB:
But while I use the terminal
free -g command, it shows me this:
dragos@madscientistlab ~ $ free -g total used free shared buff/cache available Mem: 11 3 6 0 2 7 Swap: 7 0 7
It has only 9 GB of RAM if we add the USED RAM and FREE RAM, and it has only 11 GB available in the
total column, out of 12.
Is it something wrong with my RAM memory? Or is it something that I'm not understanding?
Also, one more question: If I have 12 GB of RAM, why does Stacer say I only have 11.6 GB?
