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??

Hey all still working on it I’ll try a few more fixes today. Thank you guys so much for all the help 😭
Once upon a time I read that this can happen when your CPU isn’t correctly seated but that always sounded weird to me so idk
The memory controller is part of the CPU die nowadays.
The memory controller is part of the CPU die nowadays.
What’s weird about it? CPU seated wrong means that some pins may not be making proper electrical contact inside the socket. Pins not making proper contact means that they can’t energize the electrical traces that connect to those pins, or only do so intermittently, so whatever part of your system they control won’t work right either.
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.
What other hardware do you have installed in your system?
Can you take a screenshot of the Memory tab of Resource Manager?
It looks like the BIOS is reserving the memory for something. Reserving memory is pretty normal, but 8 GB isn’t. Have you tried resetting your bios to default settings.
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.
Same - had exactly this problem. I’m not exactly sure if I found a real fix in the end, it just eventually inexplicably started working. Think I tried changing ram slots and having to change some options in the bios - might be worth trying there as a start!
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.
Randomly one day I was playing a game and it started stuttering so it worked at one point. Got ram installed into the right slots. Tried a different set, then my old ram stick then tried with new ram and old ram. At that point it states 24gb available 7.9gb usable.
Okay, I’m back and I have slept. Have a look at your CPU. I’m 90% sure that’s where the problem was when I had this issue. I think in my case, one of the pins was slightly bent, and once it was very carefully straightened, the problem went away. But it could also be just not seated properly, or is overheating, or has dust on it.
Tried but did not work unfortunately
I saw in another post that you borrowed your partner’s RAM. Is it possible for you to borrow their CPU (assuming it’s compatible with your mobo)? If all the RAM is usable when you’re using their CPU, that would point to your CPU having an issue, as there is the potential for a failure there that’s not visible to the naked eye. If the problem still happens with your partner’s CPU, then at least you’ve eliminated one possibility, which is useful for diagnostic purposes.
I’m inclined to agree that the CPU might have been set incorrectly / have a bad pin, especially after the black screen and BIOS errors after updating.
Unfortunate, but it happens to the best of us.
OP try this one! Please!
If you reseated the CPU and tried different RAM already it could be you have a defective motherboard. I read some other threads where that was the case.
If a big chunk of ram isn’t available this is usually because your system is using at as video memory, typically in the absence of a full GPU card. If you don’t do a ton of gaming or video editing you can probably go into the BIOS and reduce your video memory to 1-2GB, or if you have a separate GPU then set it to as low as possible.
Does the GPU have 8GB of memory?
This sounds like a problem we had back in the 32bit days. Video memory from the GPU is mapped into the normal memory space. Systems with 4GB could never use all of it because of that.
This still happens with 64bit systems, but the address space is so big the video memory doesn’t overlap with system memory addresses anymore.
I think there is a BIOS setting to force that mapping into back into the first part of addresses. Might want to find that setting and make sure it is off.
Where would that be in bios? I’ve got an asus but unsure currently what specs
Mine is under the advanced tab and video memory. Of course my computer is 10 years old though so it has an actual BIOS, newer computers have a similar UEFI menu.
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”
The amount of RAM your system can support is determined by your processor, not your motherboard, and it’s been this way ever since the memory controller was moved from the motherboard’s northbridge to the processor over a decade ago.

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??
Do you mean you’re getting an error message saying the “selected file is not a proper BIOS file”?
Or are you getting a different error? If it’s the above, you’ll need to remove and redownload the updated BIOS, as it was corrupted during download, and you’ll need to make sure you have a stable connection while downloading to avoid it happening again.
If you’re getting a different error I’d need to know the exact wording to help any further.

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.
Cpu is a ryzen 2600, it doesn’t have an iGPU.
The R5 2600 doesn’t have a GPU on board, so no built in GPU in this case.
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?
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.)
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
You’ll find that 80-95% of your games work in Linux. Proton is amazing.
Is it still true that proton has issues with multiplayer games? From what I read last time I looked anti-cheat doesn’t work with proton.
how much is in your computer? just 16gb or is there more ?
Just 16 but I tried 24 as well just to see
