Windows 10: Hardware reserving half my RAM

I've been trying to fix a problem where my hardware will reserve 8gb of RAM, and my pc won't use my graphics card, even though it says its working fine, I believe the problem might be because of integrated graphics, that is using ram, and taking my graphics card place. However I can't seem to find a way to turn it off, even in my bios, any ideas?

I'm using an ASROCK AB350M motherboard, NVIDIA GTX1050, and 16gb of RAM.

Half RAM allocated to "Hardware Reserve"


Hello everyone. I really hope you can help me. I'm at the end of my rope.

First off, my specs:
Gigabyte 990FXA-UD3 mobo
AMD FX 8350 CPU
2 x G skill 4 GB sticks
EVGA 660 Ti GPU
OS on SSD
2 x 1 TB mechanical drives

Only half my RAM is showing as usable. The rest is shoved into hardware reserved. It doesn't matter what channels I use or even what RAM I use, it cuts whatever is in there by HALF. I even tried 4 sticks, cuts 16GB into 8GB.

I've tried CLEAN installs of Windows 10 AND 8.1, still cuts in half.

I've send mobo back to gigabyte, they tested and found no problem.

I tried a different CPU, still cut in half.

I tried different GPU, still RAM halved.

I've tried editing registry, unchecking that box for "maximum memory" in the msconfig boot menu. I've looked all through the BIOS and tweeked different settings. Nothing.

I'm hoping someone can help. I don't know what else to do here.

Included are screenshots.

I have almost same configuration and this is what it looks like here:



May be important that I'm using BIOS, not UEFI.
