Thread: 64bit Version and files bigger then 4GB

  1. #1

    Question 64bit Version and files bigger then 4GB

    I have a system with a Athlon II X4 620 (4x2.6Ghz) and 8GB ddr2 800. Now I would like to know if there is a 64bit version so I will be able to use the full 8 GB ddr and not just a part of it like with Windows.

    Also I would like to know if the format of the hdd Opensuse uses is able to handle files bigger then 4GB like the NTFS system under Windows. I ask this cause I watch Bluray images of up to 50GB and also have some backup ISO's of 20GB which I want to store on the HDD.


    Thanks!

    Sure, didn't you see that openSUSE is offered in i586 and x86_64 versions and have been for a while?

    No problem with your file sizes, ext3/4 which are the most commonly used Linux FS have been able to handle large files for a long time. This is not related to the RAM limit.

    ext4 - Wikipedia, the free encyclopedia

    has a filesize limit of 16TiB

    ext3 - Wikipedia, the free encyclopedia

    has a filesize limit of 2TiB at least. But drives are starting to get this large, so the move is timely.

    Thanks. But do I need the 64bit version to use my 8GB ddr fully like in windows or does the 32bit evrsion of linux also uses the full 8GB?

    In my opinion 64bit version is better for you. Because you 64bit version exploits all resources of your computer.

    Hi,

    if you use the "PAE" kernel, you can use more than 4 GB of mem
    This kernel supports up to 64GB of main memory. It requires Physical
    Addressing Extensions (PAE), which were introduced with the Pentium Pro
    (from software.opensuse.org: Rsultats de recherche)

    (but there is still a limit of 2 GB per process, IIRC).

    Novell published a couple papers relevant to this.
    This link is to supported max files sizes for various file systems and contains a link to any kernel restrictions.

    A.4.Large File Support in Linux

    Although written for suselinux, should apply to openSUSE as well.

    I am using 64 bit opensuse 11.4, on an athlon processor (probably a slower processor than yours). It is working fine.

    You should be able to do most of what you want with a 32 bit system. That will probably install the desktop kernel which has pae support and should allow use of all of your memory. But it is probably best to go with a 64 bit system.
