free tells me my total physical memory is 14.5G, but it’s supposed to be 15.5(16 actual, minus the 640K). I thought it was the swap buffer, but that’s off and systemd-swap removed.
It doesn’t seem to be allocated as a ram drive (Doesn’t show up on lsblk).
I’m at a loss. Where might I find my missing RAM?
I cant explain well but in short free can not handle the Btrfs system.
Maybe also interesting for you
Thanks, but free is about RAM, not disk space. Though I didn’t know that about BTRFS and free space on the disk, so thanks for the educational post

Some of it might be reserved for an integrated GPU (if you have an integrated GPU), even if you’re using a separate video card.
I’m sure there are ways to check where RAM is being used by the system, but off the top of my head, I don’t know any of the commands.
Oh, DERP
Thank you, @tardy. I forgot I had changed that when I installed Garuda. You know, because mushy brain. 
I always check to see if the car keys are also missing. If so, given those two like to hang out together, i check the deepest reaches of my handbag… its nether-regions, if you like… but if not there, it’s always down the back of the sofa that reveals them.
If only the ram is missing but not the keys, i know it’s serious, hence alert the cops.
Doesn’t everyone like the nether? If they play Minecraft, I mean.
