Question High RAM usage

[Bezolek]

Hi, so recently I upgraded my rig to r7 3700x, rtx 2060 msi, 2x8GB Corsair 3600MHz CL18 Vengeance RGB. But something strange occurred. My RAM usage is waaay off. My user uses only 3GB, but windows shows ( and other programs ) that 80% (sometimes even 95% ) of my RAM capacity is used. I can't lunch any new AAA games like Bordelands 3 cuz of my memory issue. Could you guys help me?

If you go to "Control Panel > System", is all of your RAM usable?

Well. I guess it's. It shows 16GB of installed memory.

In Task Manager under the Processes tab, which programs are using most of the memory?

Browser (opera), but it uses only 3GB of ram

And nothing else in the list that uses much RAM?

What is your motherboard and have you looked at the settings in the BIOS?
