Yesterday my computer completely failed on me on coming home in the afternoon.  I had posted something earlier about it but now I have pinpointed the problem to my NVDIA GeForce 8800 GT card upgrade which I have had in the MacPro for over a year now.  I have had fan issues with it before but now it is completely gone.  I reinstalled the original card that came with my 2006 MacPro and all is up and running.  Now I am at a loss as to what to do.  Has anyone else had these issues with the upgrade kit cards failing like this and the NVDIA site and support says that a black does not fall under their warranty coverage.  So basically although the card is used for me to view my Cinema Display, should it fail on me leaving me with a black screen then I am left with spending $300 for one year of having what was a great graphics card when it worked.  Unless there have been any issues or updates that someone else has and a workaround, which any advice would be greatly appreciated.  Thank you in advance.

    ATI 5770 $249, $30 less than the 8800GT for 1st gen that Apple sold but stopped selling at the end of 2008 / Jan 2009, unless you bought off an ebay seller of course.

     

    Trouble is with nVidia quality.

     

    you need 10.6.5 already installed for the 5770.

    So you would advise to stay away from NVDIA then?  Not to belabor this but I do appreciate your input.  Thank you.

    Apple drivers for Nvidia are not very good, there are none being sold, not even off ebay for EFI32 (which means having to have two editions).

     

    Apple is forcing you to stay away, I am not. I like seeing choice and better support. I have bought half a dozen Nvidia cards and only one was flawed. I even had waited months to avoid the "1.0" early edition. So this time bought first AMD since $300 ATI 9800, a couple $200 Mac Edition 9200 and others. I always figure $200 is a nice price.  This time I got a PC HIS Radeon which are well built, extra cooling pipes. HIS Radeon HD 6870 IceQ X Turbo No Mac support, at least for now but that's okay.

    Before you chuck that card away, try fixing it first.

     

    G92 cards suffer from having lead free solder.

     

    WHatever they replaced the lead with isn't nearly as flexible and causes the GPU core to lose contact with board over time.

     

    You have better than 50/50 odds of ending up with working acrd again.

     

    And if it doesn't work, you haven't lost anything but 20 minutes of time.

    I have done this with many 8800s, it frequently fixes them.

     

    Mac Pro Systems in San Jose sells a variety of 8800 cards for 1st Gen Mac Pros. DV Warehouse and WeLove Macs have the 1st Gen 8800s as well. They are also still available on Ebay, but if you have extra slot space, look for 8800GTX, has nearly twice the bandwidth of original 8800. The dual slot versions have larger quieter fans that help keep thermal stresses down, giving them longer lives.

     

    But try baking first. What have you got to lose?

    Thank you for the advice.  Its something I would never think to do, but what the heck, I'll try it.

    Not to belabor this and once again any advice would be GREATLY appreciated.  What exactly does "Die" mean in reference to removing the Thermal Paste and after cooking replacing it.  I cannot find out which part this is in reference to on the stripped card.  Want to thank you again DP for the advice and will report back what I come up with.

    The die is the exposed metal part of GPU that directly makes contact with fan.

     

    You can use a solvent like alcohol to dilute whatever remains on fan instead of buying new

     

    This stuff is supposed to fill any tiny holes in the surfacr between die and fan to acheive 100% surface contact.

     

    Very little is needed, most people apply it like peanut butter, completely wrong.

     

    Less is more.
