2 PCI-E Graphics cards.

[FacialTurd]

Hi, I currently have a P6N SLi and 2 Graphics cards, an ATi HD 3870 and an nVidia 9800GTX. The nVidia card is in the Primary PCI-E slot, and the ATi in the second (It was after I installed OS X).

 

I have the 9800 working with Full QE/CI and resolution with 2 Monitors. My 3rd Monitor is connected to the ATi Card, but is not detected (The ATi Card is shown in System Profiler, but with nothing in the "Display Connector" Section.) I have used 3 sets of drivers, Natit detects the card, but doesn't do anything with it, nothing much is said in the system log. ATY_Init detects the card and powers the fan as if it is processing something, and says a few things about detecting an LCD display in the system log. "Universal Injector" has the same effect as ATY_Init.

 

The 2 cards work in Windows Vista and 7 with the ATI and nVidia drivers installed, with the SLi PCI bridge enabled; giving me a spanned desktop on all 3 monitors.

 

I know this is an Odd setup, I would rather have 2 9800s but don't have any money to buy one.

 

Information:

OS X 10.5.7 From iATKOS v7, with the 9.7.0 Voodoo kernel

4GB Physical RAM

Both cards have 512MB of Video RAM
