Less ram is shown by fedora

My computer have 8gb of ram. But, fedora desktop shows only 5.8gb ram. Why is that? Also, on a fresh boot, the ram used 1.2gb, which in general remains around 700mb? What to do?

Hi @mayank , welcome to the forum. Please take a minute to go through the introductory posts in the #start-here category if you’ve not had a chance to do so yet.

Could you please paste the output of fpaste --sysinfo --printonly? That includes lots of system information including memory usage.

For onboard / oncpu graphics, some system will reserve certain amount of memory for graphics’ use. So Linux will see less memory than physical.

is not also the new way of swapping taking memory space? Is this active by a default installation?

In my computer, lsmem shows 15.5GB Total Onlione (16 physical , 0.5 for graphics, so correct for me)

But in Gnome-Settings-About, it only shows 15.1GB.

So why 0.4GB are “missing” ?

When considering free vs used RAM in Linux be sure to consider this as well:

https://www.linuxatemyram.com/

This might be the difference of GiB and GB, meaning GibiByte and GigaByte.

https://www.gbmb.org/gb-to-gib

But this should result in round about 1 GB Difference.

Someday they changed the measures. I long believed that 1 GB has 1024 MB. Once true (not sure however to when, 1996?), this today is wrong, for quite some time now. So 1 GB has 1000 MB. But 1 GiB has 1024 MiB.

Sometimes it is a mess what is shown, GiB or GB regularly changes depending on what tool is being used. Adds to the confusion.

10^3 Vs 2^10 is mainly happening in Disk space discussion.

For memory, I do not aware 10^3 is being used.

Hrm, can you also paste the output of these commands too please?

lsmem
sudo dmidecode -tmemory

You may need to install these pacakges:

sudo dnf install dmidecode util-linux

A distinct possibility here is that your RAM sticks are faulty. See here for example:

Are you sure that 2GB isn’t shared memory being reserved for GPU?

Please post your result of below command: mine shows 512MB.

This is the output of htop.

So yes, you machine reserved lots of ram for video use.

Normally, you can boot into System Firmware (BIOS) to change the amount to be reserved.

Ok.
How much video memory is appropriate?

It really depends on your usage pattern.

What I find so far, for normal desktop usage, single monitor at 1920x1080 resolution, 512MB is needed.

@mayank : just a quick note, please use the formatting tools to correctly format command outputs etc. it just makes your posts much easier to read. I’ve edited your posts here for the moment.
