Hi ! I am a newcomer in the Arch community and I tried to install Steam, as the player I am. My problem is that my RAM (which should be ~ 8GB) is not recognized completely, I don't know how to explain, you will understand by reading. So, here is the output of free -m :
total used free shared buff/cache available
Mem: 5864 4407 333 76 1436 1456
Swap: 2931 87 2844
As you can see, I only have 5.8 GB RAM. But if I do sudo lshw -C memory, I get :

Here's the corrected version:
As you can see in the memory section, I actually have 8 GiB of RAM, which is not 5.8 GB at all. When I was using Pop_OS!, Fedora, or even Windows for gaming, I never encountered any problems. While playing F1 22 on Windows, it indicated that I only had 5.7 GB of RAM, but I never experienced any issues with that. I read someday that basically, when my RAM was too busy, the missing part would merge to ensure enough RAM. Maybe it works like that, but, in any case, it obviously doesn't work with Arch. Can somebody help me? c: Thanks a lot.

Is this with an integrated AMD GPU? Some will reserve 2GiB, check the journal for confirmation (or share it here).
There is a vramlimit parameter for the amdgpu module but I think it only frees the RAM up for system usage if there is an corresponding option in the firmware settings: https://unix.stackexchange.com/question … -vramlimit

Are you using zswap or zram? https://wiki.archlinux.org/title/Zswap

No, it is a GeForce GTX 1650.
Are you using zswap or zram?
I have zswap and the only proposed command when I do zram in the terminal is zramctl that gives me this output :
NAME ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT
/dev/zram0 zstd 2.9G 986.6M 87.3M 107.9M 8 [SWAP]
So, if I think well, I have zram too.

You've zram and combining that w/ zswap makes no sense: https://wiki.archlinux.org/title/Zram#Usage_as_swap
Add a swapfile, disable the zram and see what happens to your RAM

I just did this, and nothing changed concerning the displayed amount of RAM but I now have a Swap.

Please post your complete system journal for the boot:
sudo journalctl -b | curl -F 'file=@-' 0x0.st

I cannot send it directly because it's too long, I hope it works.

Seth, sorry but I did not understand your answer. Maybe because of my lack of experience. Btw, what is the link between RAM and GPU ? And here is the output of lspci :

Scroll up to comment #2, the correct answer is "yes, I have and I'm now gonna check my firmware settings"

Yes, sorry. I misunderstood the answer. Despite this, I see now that I have no option to disable my integrated graphic card in my BIOS. I tried to reduce the size of VRAM used by the iGPU but with inconclusive results. Is it able to disable my iGPU and, if yes, how is it possible, please ? Thanks a lot for helping.

Tried how and why and how exactly were the results "inconclusive2?
You can ignore the iGP but that's not very likely to add some RAM (it's not announced by the DMI, the fix will have to come from the firmware)
dmesg | grep 'kernel: Memory:'
is the relevant line here.
If anything you could maybe https://wiki.archlinux.org/title/Swap_on_video_RAM

That's okay, I just bought new and larger RAM because, anyway, it was way too light for my needs. Thank you all for your answers. They helped me understand the problem, and I now know that's normal. See you
