Hello.
I've got two GPUs:
1. GTX 1060 6 Gb - plugged in PCIx16 3.0
2. GTX 750 Ti 2 Gb - connected via riser into PCIx1 2.0.
OctaneBench sees both cards but runs test only on single one.
When I select booth cards the app shows following:
GeForce GTX 750 Ti (2): and unspecified error occurred CUDA error 2 on device 1: out of memory -> failed to bind device to current thread.
If I restart the OctaneBench and choose test for 750ti - it runs but now 1060 has the same error "out of memory"
The Demo Octane for C4D also sees both cards but renders only on single one.
Whatever card I choose for render first - another one become unavailable for rendering - black viewport.
The log indicates following:
<<< Render failure detected!!! >>>
Please check render statistics to solve the problem.

Free VRAM is too low!
Help me please to figure out how to bind both GPU for render.
Thank you.
