Hello there,

I got a problem with the graphic card in my EGPU. I was a bit confused after I read a lot of different posts and guides about there problems with fixes. I was prepared for the war against the error 12 and more but well nothing happend...

I just plugged in the Razer core x with the GTX 1070 and boot up my MBP with Windows 10. Wait some minutes to let him install the drivers, deactivate the GPU from the laptop and restart again. I didn't get any error code, blackscreen, bluescreen or whatever. The Razer core is working, the GTX is detected BUT is not working. I
Now I'm not pretty sure which could be helpful. I would be thankful if someone got a solution or any guide for me.

Setup:
Macbook Pro 2015 - 15" - AMD Radeon R9 M370X
Razer core x
Nvidia GTX 1070
TB3>TB2 adapter 
TB2 cable

Are you using an external monitor? Is the Intel iGPU working to power the internal display?

@itsage No Im not using an external monitor but after I read your message I checked my device list and there is no iGPU installed (If Im not wrong you mean with iGPU the Intel graphic card or ?) .
I tried to install the intel graphic card drivers from the bootcamp driverlist but the system says that I don't meet the minimum requirements...

In order to accelerate the internal display of your MacBook Pro, either the Intel iGPU or AMD dGPU has to be active and functional. When you disabled the AMD dGPU, Windows defaulted to using a generic display driver for the internal display. Therefore it's not possible to accelerate the internal display with your GTX 1070 eGPU.

If you're running Windows 1803 or newer, try re-enabling the AMD dGPU and see whether the Nvidia eGPU can work. Otherwise it's best to use an external monitor given Thunderbolt 2 bandwidth limit.
