Anyone know what is wrong here??
If ATI 7700 is removed it works.
Drivers of both cards are installed.


Running NVIDIA 8800 and ATI 7700 gives this:

Have an inkling.

A while back nvidia updated their drivers so that a you couldn't use an nvidia gpu for physX if you were using an ATI card - they claim its a support issue, but there's a lot of gamers who figure it's an attempt at vendor lockin (to stop people buying cheap boards off ebay for physX and running with an ATI gpu).

PhysX is CUDA based, so if the drivers are just blocking all CUDA applications when they spot an ATI card, that would be the issue.

Have you got an old rig (or spare parts) you can run one board or the other on? that's probably the best bet short term.

Does it work at all with only the 7700 installed?

Aside from other possible issues, you may need a cc_config.xml file to specify "use all gpus".

IIRC from Claggy the trick is installing the drivers in the right order. Can't remember what that was though.

I don't see that Host in your Computer list. My NV 8800 & ATI 6850 work fine with XP & Win8. I'm guessing you're running Vista? Try Installing Driver 266.58 and Cat 12.8 and see what happens. Make sure you install the AMD Driver Last. If you're above 12.8 already, you will have to run a special uninstaller to downgrade OpenCL. I used this one with Win 8 and it worked great, Atiman Uninstaller v.7.0.2.msi
I've never seen that error before...

The uninstaller doesn`t work with Vista.

Thank you for your answers.

Friend solved it with removing ATI card and putted in a Quadro card instead.

It´s allways complicated to mix ATI & NVidia on the same hosts.
