I know this has been discussed by many in the past, but after updating to 10.13.4 and it having been so long since I last tried I thought I'd see if this is new behavior and if anyone has figured out a way to get it fully working.

My test setup - nMP 6,1, 32GB memory, 10-core CPU, AKiTiO Node, GTX 1080Ti, Apple TB2 -> TB3 adapter, latest Windows 10.

My latest results...

Windows is able to detect that I have a GTX 1080Ti connected and it installs the drivers.  The Nvidia installer also detects the card and installs the drivers, however in Device Manager the card never gets past the dreaded "Error code 43."  Initially I was encountering error 12 and was able to get around that by disabling unused PCIe slots/controllers, after that is when Windows was able to detect the GPU and install the drivers.

Am I being forgetful and/or overly optimistic in thinking that Apple finally unlocked/fixed the Thunderbolt lockout for eGPUs?  Or is this the same state that always happens with an eGPU on an nMP with Bootcamped Win10?

I don't recall getting this far, but it was so long ago that I could just be misremembering.

@dieseldrax What's the Boot ROM Version of your nMP? The last time I tried Bootcamp with the nMP, Windows could not detect the eGPU at all much less throwing an error. This was last fall. Maybe Apple is easing up Bootcamp because they f-up macOS eGPU support on the trashcan.

@itsage, it's Boot ROM Version: MP61.0123.B00

Thank you. I will check my nMP later today and report back. Can you also provide the Windows 10 version?

@itsage, I don't have that handy and I'm not at home but it was current as of the weekend with no updates pending or available.

I just checked my nMP which runs 10.13.4 and it shows the same Boot ROM version: MP61.0123.B00. I'm installing Window 10 1079 through Bootcamp Assistant.

Fingers crossed, would be awesome to finally have this working or at least confirm someone else is able to get to the same point which gives hope of getting it working eventually.  Thanks!

@dieseldrax I had no luck with my nMP. The eGPU never showed up. There's error 12 on the main root port of the PLX switch to which the Thunderbolt controllers attach.

@itsage, it shouldn't matter since both of the TB2 ports on the bottom are on bus 0, but I had my eGPU connected to the lower right port.

Also, when I disabled the PCIe controllers in Device Manager I used the tree view and disabled all the ones that had no devices under them (I didn't disable the one with error 12 since I knew that's where the eGPU is).  Yes, the error 12 is on the bus with the TB controllers but that should clear when you disable the other unused controllers in Windows and reboot.  That's how I got from an error 12 to the eGPU being detected but with an error 43.

I disabled two PCI roots to the Ethernet ports as well as the PCI root to the secondary dGPU. Error 12 would occasionally go away but the eGPU never made an appearance within Windows. Neither hot-plugging nor attached at boot made a difference. I knew Bus 0 to be eGPU-friendly so I tried those two first. A mixed of different TBT Buses was tried as well for monitor connection and eGPU.
