I've got two Nvidia cards in my machine at the moment. A GeForce 8800 GT 512MB (PCIe) and now also a GeForce 6200 128 MB (PCI). I got the 6200 so that I could use three monitors (1920x1200 + 1920x1080 HDTV on the 8800 and 1600x1200 on 6200). Now, the problem is that I can't seem to get them to work at the same time.

I can get either card (at least resolutionwise, didn't check if QE/CI works on 6200, 8800 works 100%) to work when it's the only card in the machine, but how do I get them both to work at the same time?

I've tried using EFIStudio to make the hex and also tried gfxutil to get the device path because I thought that was the problem since EFIStudio seems to try to have the same path for both graphics cards. gfxutil -f display shows only one string.

So to sum it up:
- How do I get the device path (PciRoot) for both cards?
- How do I create an EFI string so both cards work at the same time?

Thanks in advance

Answering myself. You need to take one graphics card out, use gfxutil to get the device path, then swap graphics cards to get the second device path. Following http://aquamac.proboards106.com/index.cgi?board=hack1&action=display&thread=569 helped me a lot, now both of my graphics cards are working (QE/CI enabled). Getting my HDTV to show picture required a lot of fiddling with the TV settings for some reason but now it also works nicely.

 I am trying to run two cards( Nvidia 7600 GS and Nvidia 7300 GS ) on my hackintosh (check signature for specs) too .. I applied the strings for each pci-e with correct addresses, when I plug just one card on any slot it works with no problems ( either primary slot or secondary)... But when I plug both cards at the same time only the card in the primary slot works until the apple logo crashes ..... The card on the second Pci-e slot does not work from the beginning of the startup from the bios level...
   What am I doing wrong??
  is it smthng to do with the mobo?

 I know from the posts that a lot of people run two graphic cards on their hackintoshes I just have to solve this too for my third monitor.
   Please help

Can't get 6600GT and 7300LE (both pci-e) to work ...


running single each will work fine with qe/ci, but when together will just give black screen when loginmanager loads.
