    Linux not registering all of RAM

    I recently built my first computer and I'm having trouble with Linux registering all the my 16gb RAM. It currently only registers half of that. I read all the forums and still can't find a solution. The BIOS recognizes 16gb, so it seems maybe it's something with Linux? It could be a hardware fault, but all the parts are new.

    I tried the RAM slots A1/B1 and A2/B2, and they both gave me the same specs as below.

    ASRock B450M Pro4 motherboard and its manual
    Two sticks of G.SKILL 8GB DDR4 - 3200 (If you look at the code below, the sticks are running at speeds of 2133 MT/s, which is much slower speeds than advertised.)

    The issue is quite aggravating and any deep look into this is much appreciated.

    I'm technically running Linux Mint, but it's based off of Ubuntu.
    uname -a
    Code:

    cat /proc/meminfo | grep MemTotal
    Code:
    MemTotal:        8093584 kB
    Which is 8.093584 gB

    sudo dmidecode --type memory

    Re: Linux not registering all of RAM

    Have you updated UEFI? AMD put out fixes for Linux and vendors are releasing updates to UEFI.

    What version of Ubuntu?
    You probably need 19.10 and maybe newer kernels & drivers.

    Vendor updates should be available now as it was July when AMD released to vendors the fixes.

    Have you tried using each memory stick alone? It maybe one is DOA.
