<p>to use cgminer on the ATI only, you can disable other opencl drivers to keep only the AMD one in the registry :</p>

<ul>
<li>HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors</li>
<li>HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Khronos\OpenCL\Vendors</li>
</ul>

<p>There are 2 different keys for x86 and x64 binaries</p>

<p>I had the problem on my PC which has 3 different opencl drivers (Intel + Nvidia + AMD)</p>

Your issue is trying to run ATI and Nvidia video drivers at the same time.

Many people mine on Linux LiveUSB.

This would be different if
a second GPU was so that you could get both of them to mine litecoin at the same time.In that case you would want your GTX680 not only mine but also display, where your other ATI card would do nothing but mining.

The system begins with the graphic card in the PCI-E closest to the CPU, all drivers were installed for Nvidia first

Put 7950 in the machine

Windows will ask to restart the system, I guess to figure out that it's had a hardware change, so restart

Install AMD drivers

For Windows to see the card, plug it into another monitor. Another way is too use a dummy plug: <http://www.overclock.net/t/384733/the-30-second-dummy-plug>

to use cgminer on the ATI only, you can disable other opencl drivers to keep only the AMD one in the registry :

* HKEY\_LOCAL\_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors
* HKEY\_LOCAL\_MACHINE\SOFTWARE\Wow6432Node\Khronos\OpenCL\Vendors
