    I hope someone has an solution for this problem!

    I have a g5 dual 2GHz. It came with a 64mb ati grafik card, and i put in a ati Radeon 9600xt with 128 Mb. This is the one that comes with the build to order Mac g5 dual 2 Ghz and also with the newer ones.

    now the funny thing is that everything workes fine, exept of the fan (the top one, next to the speaker) runs at full power. I did everything (firmware upgrade, Param resets, motherboards resets), talked to specialists of allkinds, and finally talked to apple care, there anwser was great:
    We do not support you if you change the grafik card, even if it’s the one that comes build to order on the same machine!!!

    ok, i figuered maybe someone has an idea how to make this settings in the firmware. im sure its only a change in a variable. i have the same machine runnig fine with the same grafic card. So i know it is possible, the only diffrent that it came biuld to order with the card!

    any hints on open firmware, how to find out the fan settings or the grafik card settings, are very welcome!

    Thanks in advance!

    Is this an Apple ADC video card, or a burned PC card?

    There's a good chance that a burned card would have problems you wouldn't expect.

    What is a burned PC or a Apple ADC video card

    Im sorry, but i have no clue what a Apple ADC video card or a Burned PC card means?

    On the otherhand, i can say that the exact same card, that came build in (Build to order) from apple, works on the exact same machine (same everything!). The only diffrence is that the one causing the fan problem had originaly another video card build to order! as soon as we put in the other one, "ati Radeon 9600xt with 128 Mb" which one can not buy, only order "build to roder", the fan starts going fast! really fast, Like a 747 taking off fast.

    so... i suppose it has to do with a build to order firmware setting, or somthing like this


    Thanks for your help,

    What monitor are you using?

    Does it do this with that monitor plugged in?

    Did you install the ATI drivers AFTER the last OS X update?

    If so you may want to try to reinstall the OS X update with the newest ATI drivers from here...


    The only reason I asked if it wasn't an ADC video card (a port that is only on Mac video cards) was... a Wintel world card with a Mac ROM hack onto them are not supported by anyone -- because of all the problems that can crop up.

    Edit: Also look & post here...
