What other software do you have on your server? mail server? antivirus? cPanels uses a lot of RAM too.. connect to your VPS terminal then use the TOP command to see all running processes and their respective resources.
High ram usage isn't always a bad sign though.
Also, does your sites use some type of caching like redis? A lot of caching solutions uses RAM... Even if you have a low IO, those request could have generated cache data that was stored on your RAM... Usually, that's good, that's what's RAM is supposed to do anyway.
