When I run free -m, I get different data from when I use htop.
free -m:
total used free shared buff/cache available
Mem: 992 396 149 23 446 392
Swap: 0 0 0
htop:
Mem[|||||||||||||||||||||||||||||||||||||||||||||||||456 ]

Information:
- RAM: 1GB
- OS: Ubuntu 16.04.3
I know for a fact that I have 1GB of total RAM, showing that free -m is accurate with that. But how come htop claims that the max RAM is only about 512MB? I can say that I had 512MB until I upgraded to 1GB about 12 hours ago. I did reinstall htop but that didn't help; I still got the same results. So why is it that free -m claims that I have 992MB total RAM and htop claims that I have about 512MB?

Perhaps you are misinterpreting what htop is telling you, I don't see anywhere that htop says you only have 512MB of memory. You can get a definitive answer by configuring htop to display numbers rather than a graph. Go to settings F2 -> Meters -> Memory and then press the space bar. This will rotate through the memory display options, one of which is text e.g.
