I have an NVIDIA 8600GT and two ATI 4870x2's in the same computer, and I have had some huge issues trying to get OpenCL to work correctly. I am running Windows 7 x64 HP with all of the updated drivers, but had to completely uninstall all of the NVIDIA software, as well as disable to hardware in the Device manager just to be able to run some sample applications.
Now, I know that the ATI hardware is much more powerful than the NVIDIA hardware that I own, but I am very interested in running all cards simultaneously. Has anyone else tried this? Does anyone have a working solution, or even a guess?
From what I was told, the NVIDIA software is not playing well with the ATI stuff. I am wondering maybe I can install the drivers/SDK's all in the same folder on the Windows partition, or something similar to make sure that everything is at the same access level, but I have no real understanding on why I am having this problem.
I look forward to the wisdom of the members that may know more!
