Too Much Hardware Reserved Memory, Have Tried Several Fixes

I am having issues with too much system reserved memory (currently 5.0gb system reserved with 3.0gb available). I am running 64x Windows on PCI Express 2.0 CFX X58 Pro. I have 2 identical 8gb sticks in. I have 2 identical 4 sticks as well (not installed). I have had all four of the ram sticks in simultaneously before and it showed 24gb, 21gb hardware reserved. So basically no matter what I try I only have access to 3.0gb. Although I would like to know why it isn't currently reading my second 8 stick, the more immediate question on my mind is how to free up all of that hardware reserved memory.

I have looked through all of these for solutions to my issues and none have worked.

Hi, have you read thru e.g.
Hardware Reserved Memory 5.5GB - Windows 10 Forums
Problem about RAM Hardware reserved. Need advice. - Windows 10 Forums
Hardware reserved memory issue - Windows 10 Forums
Installed RAM 16GB (7.18 usable) Solved - Windows 10 Forums

- more if you search for
hardware reserved

Have you checked/tried everything in those?

I have also tried the solutions here: What Can I Do When Windows See Less Usable RAM Than Installed | PCsteps.com
Except I could not find either of the settings this suggests I would find in my BIOS. Both methods of changing the boot options in msconfig did not work. I did NOT update my BIOS yet, but I am on the second to most recent version anyway.

I also tried changing the setting in registry editor as shown in this video here: Hardware reserved memory FIX (3 ways) - YouTube
Interesting note: before changing this value my computer was showing I had 24gb installed (even though I only had 16 in), then after changing it, it showed I had 8gb installed (again, even though I have 16 in.) This is the first thing I have tried that changed anything though.

I have also tried a fresh install of Windows while trying to solve this issue.

Hopefully helpful screen shots:

Have you tried to run this in CMD as admin?

Code:

bcdedit /deletevalue {current} removememory
bcdedit /deletevalue {current} truncatememory
bcdedit /deletevalue {default} removememory
bcdedit /deletevalue {default} truncatememory

I just tried the first line, I received this error:
"An error occurred while attempting to delete the specified data element.
Element not found."

Although if {current} is supposed to be filled in with something specific to my system, I wouldn't know what to fill it in with.

Lots of info about that issue and that chipset here,

#8 from here has been one of the biggest culprits for causing this that I have seen over the years.

Lots of information in that link that I do not understand. It will take me some time to go through all of them, thanks.

Hi,
If msconfig shows normal startup most likely is if the two 4gb sticks do the same thing you're on a 32 bit os or corrupt bios

Optimize default
Clear cmos
Fresh bios
Roll back bios
See if any of those work using the 2x4gb sticks only installed.
