My computer is not using all of the RAM on my computer.

Hello, I'm user of X5650 System. Im not english so my post is not good at read, i beg your pardon.
I'm using 14gb ram (2GB X 5EA + 4GB 1EA with same clock)
I'm using Dual mornitor and Primo Ramdisk server edition (2GB dynamic? kinetic? ramdisk)
When I run game that using a lot of ram like BF1 or GTAV, while running chrome 4+ tabs,
My computer didn't use more ram than 8.7GB (reduce ramdisk 1gb, 9.3GB)
So while playing game, frame dropped hard..
i don't know why, virtual memory page set on disk e WITH AUTO (C: SSD 240GB WIN , D,E,G:HDD)
no effect disable virtual memory page. (adverse effect)
why my computer cant use left 4gb of ram? why?

Hi,
Use resource monitor memory section and see if you have a large hardware reserved block.
