[Bf-cycles] Recent builds crashing - Cycles CUDA rendering

[Le Jardin Digital]

hi
i don't know how to select what GPU to select for rendering.
But i did an interesting test: with GPU-Z, it indicate that only the 
GTX285 is working (100%).
The 470 is at 0% ( with previous version (non multiGPU), it was the 470 
which was at 100%, and the 285 at 0% ).So 2 things:

* does exist a panel inside blender to select the GPU ? ( i've search, 
particulary in the cycles section but found nothing...)

* Is there a setting to tweak in the Nvidia driver control panel to make 
both to run ( with octane render, both work on this sytem )?

thanks
