    Exclamation asus maximus iv extreme + HD 6990 problems


    I would like to ask if anybody else has some similar problems or if anybody was successfully solved those thing/s ?

    --asus maximus iv extreme rev 3 motherboard
    --bios revision 1850
    --asus HD 6990 graphic card.
    --running on 64 bit ubuntu 11.04 with kernel natty
    --or running on kernel 3.0.3 taken from ""
    --catalyst 11.8

    1) software problems:
    --previous versions of oneric kernels did not work at all - really freeze.
    only cold reset helped
    --no rendering at all. catalyst from 11.6 up to 11.8 versions.
    Many attempts to re-install in console did not help.
    partly result of this command
    LIBGL_DEBUG=verbose glxinfo |grep rendering
    dlopen /usr/lib/fglrx/dri/ failed (/usr/lib/fglrx/dri/ cannot open shared object file: No such file or directory)
    libGL error: dlopen /usr/lib32/fglrx/dri/ failed (/usr/lib32/fglrx/dri/ cannot open shared object file: No such file or directory)

    tried to create links for library according to this:
    $ locate

    did not help.

    -- I cannot use open source ati driver because temperature has been increased within couple of minutes to 60 degrees Celsius on air cooler output ! and went to freeze.

    -- comparing the glxgears perfomance: open source vs. proprietary catalyst driver:
    open source ~ 4000 fps big fluctuation, proprietary over 14.000,- fps on older kernel (catalyst 11.6 patched).
    From kernel versions > 3.0 (catalyst 11.7,11.8) I have got max 12.200,- fps.
    Comparing to my very old nvidia geforce 7920 GTX Go (laptop) graphic card where proprietary nvidia driver version 280 got ~ 2500,- fps (kernel
    Quite funny. I would expect from HD6990 quite better performance.
    Proprietary catalyst drivers from version 11.3 to 11.8 have always some problems. Installation or something does not work.
    So, concerning the graphic performance I have experienced similar thing to: ""

    If anybody has experience with nvidia 590 please do not hesitate to share experience ?

    -- sometimes I have noticed the small choking even if processor and graphic card is almost idle.

    2) hardware problems with motherboard:
    -- randomly disconnected SATA II or SATA III hard drives. Running on ACPI. approximately monthly period. Does not matter if hot-plug is on/off.
    -- BIOS from 1309 to 1850 versions does not detect any firewire PCI-E card . Does not matter if it is connected to x1, x4 or x8/16 PCI-E slot. Advice from ASUS technical support - buy more and more firewire card/s until some is going to work. Oh yes, they have such sense of humor. Firewire cards definitely works in another motherboard without problems.
    -- BIOS does not reliably detects all connected devices in seeing in boot menu. Sometimes is missing flash card, sometimes usb disk.
    -- ubs 3.0 sometimes is going to disconnect device (no matter if hd or flashdrive or something else). Sometimes I have got message of "low power".
    -- clear CMOS switch on motherboard works sporadically (according to manual I would expect better reliability).
    -- debug 2 digit display on motherboard: When something went wrong - usually shows debug code: "reserved for future error codes" or something similar - not much useful.

    Thanks for any comments, advice or experience.
