So, on Facebook, we had similar discussion, and one of the guys commented following:
-" I asked razer about this, they don't support running them together, either you run the GTX 1060 on you razer blade or you plug in the razer core and it'll use the GTX 1070, they won't run as SLI"

Hey,so where you able to make both GPUs run in octane live viewer?
I am looking forward to get similar setup.

Razer Blade full he screen, gtx1060 + razer core with gtx1070.
Just for live viewer.
