I have run 8.1 pro ( also what I am upgrading from) on the machine in question, I also have re-seated all the sticks,reset the bios ,removed any/all overclocks that were inplace, however after I regressed to Win 8.1 Pro all 32 GB are registering. The included screen shots are all while Win 10 Pro was installed and running, Both OS are 64 bit. The RAM DIMMs are dual channel 4x 8 Gb sticks of Gskill Ripjawz running at 1600MHz running on a Gigabyte 970A-D3 motherboard with a AMD

8120 CPU.

Sorry I see you are running an AMD 8120. I'm having trouble finding the memory specs for it. I assure you it has specs, LMAO

I know the CPU and Motherboard can support the 32 GB of ram, normally RAM is limited by the motherboards memory controller(memory bus). the 970A-D3 supports up to 32 GB as stated here: GIGABYTE - Motherboard - Socket AM3+ - GA-970A-D3 (rev. 1.4)
I am in the process of doing a clean install of Win 10(64bit) to see if the clean install exhibits the same behavior as before. The RAM was showing in the bios as stated in the OP I reset bios,re-seated the DIMMS and still had the same issue . It appears for some reason the system is seeing the sticks as single channel instead of dual channel. Hopefully this will be fixed by the clean install. Will post results as soon as I can.

If the clean install has no success then I would try installing the generic AMD chipset Win 10 drivers until Gigabyte release some specific for your board. That's what my money's on as being the cause of the three problems: single channel, 8MB hardware reserved and only 24GB reported.

I have just completed the 2nd installation and it seems the prior issue must have been a fluke. The system is now showing all 32 GB in system information and shows all as usable. It would appear the issue fixed itself .

Have you updated your BIOS?
*Update* Nevermind, I'm assuming that by flashing your BIOS, you'll be flashing the latest one to it.

Windows 10 Xbox is more than my expectation, really awesome

Upon reviewing my bios version it appears I was using a "modded" bios , after flashing to the actual Gigabyte f12 bios the RAM seems stable. We'll see how long it lasts this time. Though I have the XMP profile enabled for the RAM and a mild CPU overclock in place at this time ad the system appears stable after running prime 95 (blend test)for a significant length of time with no errors. Fingers crossed hopefully this fixed my issue.

Good luck!
