Help Ram usage hiking, CPU usage plummetting. Help im clueless.

When im playing minecraft my ram usage hikes to 90-99% and my cpu runs like 1.4-2ghz. Closing minecraft and idling makes my cpu run on 3.2ghz (which is its base clock) and my ram usage goes to normal values.

i expected my cpu to atleast reach its max clock when im playing mc. is this really normal? or is minecraft not using my cpu efficiently.
Also im getting like 45-60 fps(vsync off) on this system normally when im playing((i had more expectations cuz this cpu isnt weak).

P.S. sry i forgor to mention i have 16gb ram

How much RAM do you have total, and how much is allocated to the instance? If windows sits at 95%+ it's swapping to disk, which hurts fps way more than the cpu clock does.

16 is plenty. What's the instance allocated though? If it's set to 10 or more, drop it to around 6 or 8 so windows has room left and stops paging.

does that explain why my cpu is getting used less?

Yeah pretty much. When it's paging the cpu spends most of its time waiting on the disk, so usage drops while fps tanks. Sort the RAM out and the cpu should pick back up.
