Missing memory after memory added
Missing memory after memory added
I installed Debian 10 while a 4G memory stick was installed.
I later added another 4G stick, same brand, model, etc.
So now the BIOS shows 8G, but commands like top, htop, etc. only show 5.9G available.
The GPU is on the mobo.
But, I've not found a way to tell how much, or if, it using the missing 2G.
Is there a command that can do that?
Is there something else grabbing the memory?

Re: Missing memory after memory added
I have, before posting, read and tried all those.
It could be I don't know what I'm looking for...but I found nothing that indicates GPU usage.
dmidecode tells me I have two 4G memory devices.

Re: Missing memory after memory added
Mostly just posting cause was dorking around and happened on a cool command wanted to share, install the lshw pkg, ie: "sudo apt install lshw", run the thing with "sudo lshw -short > specs" which sends that output to and makes a file named specs in users home directory. It's pretty interesting to look over and not like there's a shortage of great tools for showing whatever system info a nixer wants, lspci, inxi etc etc but Op you say my gpu, my mobo, my new brand of RAM, my this + my that, might want to include some info about what those things are eh.
Ps, have mentioned "smem -tk", smem, awesome util for showing exactly which processes-progs are using how much system memory, think its really cool and jmo, yep system reserving memory for video does seem like a good candidate as something to check in this mystery of the missing 2gigs. Off the top dont remember or never learned the relevant progs + cmds to deal w such a thing, google knows everything though. https://duckduckgo.com/?q=memory+reserv ... =h_&ia=web

So a lot of output and in several places 2G of memory listed, but not sure how to tell if it's on the mobo or in the ram cards...

Ps, this is set in the chipset = uefi-bios, on your mobo, look around in them for settings to adjust vram, shared memory or etc. If not, might see if there's a bios upgrade available for your system. Check in any notes about what it provides if so, possibly ask in an Asus forum or AMD's ? Well at least now you know and which utils and tools to use. Am not really up to speed on this topic, only ever bothered learning a broad overview of what's involved, maybe @stevep will pop in and offer some insight. Yep imo 2gbs-mem dedicated to vram kinda stinks, should be a bios setting to change such a thing, if not big red X on a given brand or model of pc's.

Re: Missing memory after memory added
Yes...it says "video memory".
I don't see what indicates this is part of the system RAM or is part of the onboard GPU system...
I agree it seems this is the missing memory. It certainly confirms the graphics has 2G, but, not where it came from.

Re: Missing memory after memory added
See above post edit, it's understandable but figuring this out is basic search and tech-related information too. Should be able to be adjusted, as mentioned imo should be easily available settings for something like that supported in system bios. If not id be mega-pissed off too. Xyz pc would be getting stamped return to sender-point of purchase ASAP. Anyway dont have an easy answer or suggestion for this type of thing. If it turns out this is hard to work around, buyer beware i guess.
At this point have more questions than anything and not willing to dump the time suggesting this, asking that etc. Can only say good luck and hoping @stevep or the all knowing and seeing of everything tech, Head_on post something on this thing.
Ps, on the brightside 6gigs of RAM is a nice chunk no matter what, so at least you've got a nice system to play with.
