hey all. I’ve tried different ram, a different windows version, I’ve messed around in bios and updated it as well. How can i get my pc to register the rest of my ram??
-cross posting-
I had this exact issue a couple of years ago. Exactly the same problem: 16gb installed (and recognised by the BIOS), but Windows wouldn’t use more than 8gb, even though it could detect its presence. And right now, I’m really annoyed with myself for not being able to remember what the fix was. It was… definitely something hardware-related, not software/configuration. I’m off to bed now, so if it comes to me overnight, I’ll pop back in tomorrow.
msconfig
has a maximum memory option. Worth checking that to make sure it’s not set to 8gb.Could also be that you’ve installed the sticks in a weird configuration. Often if you have 4 slots the board actually wants you to populate slots 2 and 4 if you’re only using 2 sticks. Details are usually printed on the board.
Or could be reserve for the iGPU, have a look in the bios.
It is detecting your ram with what I can tell from the screenshot. What program is that anyways? But it a large portion is being used. I believe windows itself uses aroung 4gigs and you might just have programs in the background using the rest, even a web browser could use a decent chunk
What does task manager show?
That looks like a snippet the system properties menu in Windows. It’s detecting all of the RAM but it isn’t that only 7.92GB is free – rather only 7.92GB is capable of being addressed, due to something going wrong.

I don’t think it should be reserving 8GB in any case.
Edit: plus it’s a Ryzen 2600. No iGPU.
Since what everyone else has suggested hasn’t worked, there’s 3 more things to test:
-
Update your BIOS. Depending on the age difference between your CPU and your MOBO, the BIOS might not be configured correctly for your CPU and thus half your RAM is unable to be addressed.
-
Test your RAM sticks and memory slots individually. Put your sticks in the primary channel (per your MOBO specs) one at a time and reboot to see if they’re actually working. Then try moving them around to see if the issue is a bad slot, rather than a bad stick.

Are you sure you’re not running a 32-bit OS? You’d be capped at 4GB system memory on 32-bit Windows, for example, no matter how much physical RAM you have.
doesn’t a 32 bit OS cap memory usage at 4GB per process not for the whole system?
Sort of, it depends on implementation. There are some techniques (which I don’t really know) that will allow a 32 bit OS to address more than 4GB, but natively it can’t for the same reason that the process will still be limited to 4GB.
Perhaps you already know this but: 32 bits can only represent 2^32 numbers (4.294.967.296), which is how many bytes 4GB is equivalent to, and so anything after that cannot be reached. This also means 64 bits can address up to something like 17 billion GB, or about 16 EB.
Tried updating my bios but when attempting to through the bios itself it states “not a valid bios” even though it’s through the updater built in??
-
When did the issue start? Did you install new RAM? Are both the new sticks identical or of mixed make? A new CPU? Did you unseat and reseat the CPU or anything before this started?
You tried different RAM? Was it properly addressed or no? Did you try the current or different RAM stick by stick to verify each one is working on its own and then in the recommended slots as per your motherboard manual?
These steps/questions are necessary to determine whether the issue is a bad memory stick, something funky going on with the memory controller wrt slots, timings, combination of different modules, etc, or even the possibility of a defective memory controller or a bent/broken pin on the CPU.
Update: I stole my partners ram and put 4 x 8gb in there and now it’s showing 16 GB available. Smh. So it seems something is reserving half of my ram. I reset bios to default. PLZ help lmaooooooooo
Unlikely, but your motherboard might have an extremely low max RAM capacity.
Search for your boards specifications and check how much RAM/Memory it can suppport. If you don’t know your motherboards name, open CMD and type: “wmic baseboard get product”
Do you have, and are you using, a dedicated graphics card?
If using the inbuilt GPU that’s on your motherboard, windows will use system ram as GPU ram.
If that isnt the issue, can you tell us: windows version(s) you’ve tried, confirm all your ram sticks are same brand and size, and confirm if it’s ever worked on this computer.
The R5 2600 doesn’t have a GPU on board, so no built in GPU in this case.
Cpu is a ryzen 2600, it doesn’t have an iGPU.

I know this might not be helpful… but umm… have you tried nit using windows?
Since the PC shows the full 16gb it must be registering it. So something inside windows must be occupying the rest of the space.
I’ve seen windows alone go up to 4+ GB so the ~8GB your missing here aren’t unrealistic depending on what programs are running in the background.
I remember an old HP driver that would just take up all the unused RAM, until it was needed. Then it usually used enough less RAM to let whatever happen. This is some time ago, but I wonder if some Windows application is “reserving” RAM.
I’d recommend a more detailed look at per app and per process RAM usage. Maybe look at Process Explorer? See how RAM usage changes under load?
Only issue is most of what I use it for is gaming. Do you know any Linux distro that would be best for that? I would also like forge launcher for games with the partner
there might be hidden ram drives that helps offset some I/O to the slower SSD/sata drives. (Edit: like my Radeon replay buffer I config it to save to Ram instead of to disk, I have 128GB so I can afford keeping those buffers in ram.)
I once had a TV tuner card use up 4GB of address space taking me from 8GB down to 4GB. Do you have any add-in cards that can be removed for testing? Or maybe any unnecessary onboard devices that can be disabled in the BIOS/firmware.
Update: I installed Linux and it’s still not working I will tweak around with some of the settings yall suggested and get back to you ASAP. Also
No igpu Gpu: 1070ti ftw2 Ram: corsair vengeance pro ddr4 3600 I’ll get my mobo soon im stepping out for groceries
Only time I’ve ever had this happen, I had inadvertently over tightened my CPU cooler. Scythne ninja 2 was a godsend for small form factor builds, but damn it was easy to over tighten!
Only time i ever had this happen, i learned the key difference between 32bit and 64bit windows lol
I’ve had this happen on a system where it was either the chipset or the cpu that was unable to allocate more ram.
However that was an older system and I’m infamiliar with ryzen processors on this issue.
Hey all still working on it I’ll try a few more fixes today. Thank you guys so much for all the help 😭
