Try the sudo dmidecode -t 16 command. I suspect the computer board supports up to 4GB, and if that's the case, there isn't much you can do. — mikewhatever, Jul 31 '16 at 15:44

The maximum supported RAM for that model is 4GB so it won't utilize the second 4GB stick of RAM. Your options are to upgrade the motherboard to one that supports more RAM or obtain a different system that can or live with 4GB and add swap space as necessary to support your needs.
