Windows 10 Pro - 64 Bit, 7.93gb RAM Usable, 16gb Found?

Hello everyone, I am at a loss here with my new desktop as to why Windows 10 Pro (64 bit) is currently only allowing me to use half of my RAM. Due to a fried CPU I rebuilt this computer with some good parts:


CPU: Ryzen 7 1700
Motherboard: ASUS H97 Plus
RAM: 16gb (2x8gb)
Video: GTX 1070
500gb SSD + 1TB HD

I saw some people asking about RAM specifics, they were bought in a pack of 2:

PNY Anarchy 16GB Kit (2x8GB) DDR4 2133MHz (PC4-17000) CL15 Desktop Memory (BLUE) - MD16GK2D4213315AB

During the process I formatted my harddrives and reinstalled windows (first time using windows 10, always been a fan of 7) and have the 64 bit Windows 10 Pro installed.


When I enter bios the bios show 16gb of RAM read in the correct channels however I cant seem to allow my computer to use more than 8gb of RAM which is detrimental to a lot of the things I do on this.


Browsing countless forums Ive tried a variety of fixes, like turning off the Auto Manage Paging Files, reseating RAM, checking bios to make sure its running at the correct speeds/voltage, I have no idea what to do next.


This is currently Windows 10 Pro 64 bit, I thought it might be that I havnt activated it yet (waiting on a key) but from what I have read that doesn't affect available RAM usage.

Not that I doubt you.....but how do you know your PC is only allowing half the RAM to be used?

When I go into system information/task manager

Hi,
Hardware reserved 8.1gb's is where it is soaked up

Why well most I've read it's a bios issue where possibly seeing if there is a bios update might address the issue ?
Might also try optimize default in the bios ?

Thats what caught my eye, however running default bios settings and it is currently at the most up-to-date version, the bios also shows the full 16gb being read just fine

Hi,
I would imagine it's the amd processors built in graphic's that has reserved the 8.1gb's
How to free it up ?

Exactly....you must disable the onboard GPU and set the PCI express port as default for your GPU.
EDGE not working on Tenforums anymore

But first I'd check to make sure that the RAM sticks are firmly seated.

Hi,
I'm sure uefi bios will look a lot different that those legacy bios :)

Here in internet in a forum i found something similar. Better to read it.
1)Maybe you have bent pin?
2)clear cmos with battery.
3) run ram in lower speed.
