Can't be so. I had this same system with an MSI Motherboard and I saw
almost all the 4Gb I had before. Now I change the Motherboard,
procesor amd memory (still 4Gb) and I get this. It's not a problem
with how Linux reads memory.

Looks more like I have 500Mb used for video. :-(

Worst part is I still don't now how to lower it. Couldn't find
anything in the BIOS settings.
