Windows 10: Hardware Reserved ISSUE

Can someone help me fix this Hardware reserved. I got 8.1gb hardware reserved on my x64bit windows. I don't know why this hardware reserved a lot of memory cuz I have graphics card and a x64bit windows. Help me fix this. May pc so slow after this reserved get a lot. Also may Ram frequency is 32000mhz but now its 2133Mhz. It's annoying anyway I have 2x8 RAM Stick DDR4CPU: Ryzen 5 2600 and a GTX 1650 super 4gb.Motherboard: Gigabyte A320M-S2H V2-CF

Hardware Reserved 4GB (DIMM Slot 1B)

So recently my task manager started showing that only 12GB of my 16GB DDR3 RAM in Dual Channel was available stating "Hardware Reserved 4.0 GB"

These are the steps I've currently taken to attempt to rectify the issue.

1. Flashed BIOS
   
2. Wiped OS and installed to a new drive
   
3. Set max page file size to recommended (2.5GB)
   
4. Maximum memory isn't enabled in advanced boot options
   
5. Replaced the odd stick of RAM (I had a Kingston HyperX Fury) with the same model (now all Corsair Vengeance) so now all sticks match
   
6. Resetting CMOS fixed it for a few hours before returning.
   

I want to avoid the idea that the DIMM slot is faulty due to a CMOS reset fixing it (even if temporarily).

The RAM I'm using is: CMZ12GX3M3A1600C9 (3) and CMZ4GX3M1A1600C9 (1) Both the same model of RAM, but the 3 came in a kit for 12GB whilst the other came as a single kit of 4GB, hence the slight difference in the part numbers.

The motherboard I'm using is 990FXA-UD3 R5.

I'm asking as a seperate question due to the fact I've tried every other suggestion in the other questions and now feel that my situation is unique enough for it's own question.

 

Hardware reserved memory at 14GB!

My hardware reserved memory for some reason is at 14GB. I don't know what caused this but I've tried unchecking the maximum memory and many other suggested fixes. I understand that Windows controls the reserved memory, but this seems way too high and it's causing performance issues. How do I reduce the reserved memory to a reasonable level and free up RAM?

 

Half of RAM 'Hardware Reserved'

I have 32GB of RAM installed and half is "hardware reserved" by Windows. I've tried every suggestion I can find, including moving the modules around to different slots. My MB does not have onboard graphics. Specs:

• Motherboard: Gigabyte GA-AX370M-DS3H (BIOS on latest firmware)
• CPU: Ryzen 7 2700X (upgraded from 1700x and it didn't help)
• RAM: Corsair VENGEANCE® LPX 32GB (2 x 16GB) DDR4 DRAM 2400MHz C16 Memory Kit
• GPU: Nvidia RTX-2060 Super

The BIOS, Windows, CPUZ and HWInfo all show 32GB installed and both slots used, but Windows says "Hardware Reserved: 16.1GB". This was occurring on Windows 10. I am currently running Windows 11 (beta channel) and it didn't help. I also upgraded my CPU from a Ryzen 7 1700 with no change. Pics: Imgur: The magic of the Internet
