Thread: OpenSUSE uses less then 20% of my installed memory

  1. #1

    Question OpenSUSE uses less then 20% of my installed memory

    Hello!
    My issue is pretty simple... I have installed the newest OpenSUSE on my net-book:
    Asus 1201n (with extended memory 2GB -> to 4 GB) and everything was fine until i found out that OS uses only 700MB memory and does not see the rest (3,3GB - OK, I know that 32-bit can't use all of 4GB but there is a difference between 700MB and 3GB).
    Please help me somehow or redirect - I haven't found anything about this issue, that's why I'm starting a new topic.

    Hi, welcome here.

    Could you please tell us what is telling you that only 700MB is used?
    It's not true that the 32bit kernel cannot use the full 4GB, since PAE is embedded in the kernel-desktop, which you should be running.

    What's the desktop used?
    Which openSUSE?

    Hi.
    I have installed version OpenSUSE 11.4 with KDE (I have no idea how to check its version). software.opensuse.org: Pobierz openSUSE 11.4
    The "free -m" command showed me that my computer is using only 765 MB of 790MB and has 25 free. What's more after few reboots it shows that I have 3000MB and it uses 1000MB... now I'm totally confused

    edit: It might be connected with teamspeak 3 and this "pulseaudio" process because my computer slows down after running ts3 for a while :/

    Hi,

    3000MB = 3 GB, so it looks ok.

    In a terminal, fire up a top command to see how it reports your memory.

    or do "konqueror sysinfo:/" from a terminal and see what it reports

    Hi
    Also the output from;
    Code:
    dmesg |grep e820
    
    or
    
    sudo cat /var/log/boot.msg |grep e820
    This show the memory recognized by the system

    Całkowita pamięć (RAM): 3,2 GiB
    Wolna pamięć: 2,1 GiB (+ bufory 672,5 MiB)
    Total: 3.2
    Free 2.1 and buffers 672,5

    Seems to be OK. But what causes the loss? And how to get full 4GB/4GB?

    Wich kernel are you using ? Give us the output of this command :

    Code:
    uname -a
    I heard that if you are using the kernel-default instead of kernel-desktop, there is a difference in the RAM recognition. I don't know if it really is a fact.

    can you post the output of "free -m" here and the output of "uname -a"?

    Hi
    BIOS upgrade sometimes help. What kernel are you running? Using onboard graphics?
