Incorrect amount of RAM detected

Hello,

I recently noticed that Garuda Linux detects only 6GB out of my whole 8GB RAM. It is not an hardware issue, since Windows 11 detects it and 6GB is actually 1.5 sticks of my RAM (2 sticks of 4GB RAM). I read this post before, but the solution turned out to be reslotting the RAM.

Thank you :slight_smile:

Linux show you what could be used as RAM by system, no more, no less.
You are right, the less RAM is used by GPU.
Nothing wrong, your link point to a 12 GB RAM and one 4 GB RAM was defect.

In short, everything is fine on your board. :slight_smile:
