Need Help using Multiple Non-Identical GPUs for GPGPU

post #1 of 4
Thread Starter 
Hello,
I am looking to run a GPGPU compute task on 2 separate graphics cards in a system. I have a 5830 and a 5850 installed. I hooked the monitor up to the 5830, loaded windows and drivers. When I run GPU-Z or MSI afterburner, they detect both cards, but CCC only detects the 5830. Under "information center - graphics hardware," it lists the 5850 as a "Disabled Adapter." Is there any way to enable the 5850? I have tried using a dummy plug and switching the monitor cable, but i cannot get it to work.
Please Help!

Your hd 5850 should be your main card for a start, id put that in the first slot and the hd 5830 in the second and run the monitor off the hd 5850

You have to make a trick connector to make the 5850 think it's displaying.
