Windows XP x64 - Freezes in network access when memory above 3GB

Discussion in 'Windows 64bit' started by Gert-Jaap Glasbergen, Nov 20, 2006.

  1. Hi,

    I have a new machine where i have strange behaviour. We have a SBS 2003
    based network and active directory. When i connect to a fileshare of our
    fileserver i see - at random moments - freezes. However; it does not occur
    when i remove one GB stick of RAM (i have 4GB in the setup). It also occurs
    on 32bit with PAE, it happens with multiple network cards. I switched LAN
    ports too. None of my other clients have similar issues.


    Core 2 Duo E6400
    4x Kingston 1GB DDR2
    Nvidia Geforce 7300GS
    Onboard RAID with 2x Raptor 147GB 10krpm

    I have similar issues in Win2003 x64 too, which i tried from our MSDN set.
    I've been struggling for nearly 4 days now, with no result. I haven't had
    freezes when i removed one stick of RAM (i also tried with that same stick
    in a set of 3 to form 3GB to rule out the stick of RAM being faulty).

    When the SMB access hangs, i can sometimes reach another fileserver
    perfectly fine. Also surfing / Email / MSN access works perfectly. Just that
    SMB access will just not go.

    Any ideas are welcome.

    I remember Collin B. having the same issue with x64 and 4GB ram with
    the same motherboard. At the time he was waiting for a bios update but I
    didn't read the results. If the latest bios version is installed a work
    around may be only 3GB ram until a bios update is available.
