Please, download and run GPU-Z:

And share a screenshot from the Graphics Card tabs from both GPUs, thanks.
If it crashes with Tonemapping active, probably the PCI bus of the second GPU is too slow.
Please also post a screenshot from c4doctane settings/Devices panel, thanks.

Please, try theses steps.
  • Go to Nvidia Control panel, menu Help, and enable the Debug Mode, to work with GPUs at default clock.
  • Connect one monitor per GPU, to reduce the available VRAM more uniformly .
  • In Devices panel, enable the Priority for both GPUs, and set the Priority popup to LOW

But actually, I don't need "Use for tonemap" for both GPU, so I break up to test stuff...
