hey guys, I have no interest in an accelerated internal display.  My setup is a Core X, Titan Z (obtained for free) and a 2016 15” MBP.

if I only want external display, should I only have to hit plug and disable 1905?  I got confused as to if the whole guide was for internal screen and that is why we needed the iGPU working.

Right now I have drivers downloaded and recognized GPU, just getting error 12 even with 1905 off, and 1901 freezes my system.  Any help is appreciated

Pending: Add my system information and expected eGPU configuration to my signature to give context to my posts

Same exact issue, I would love if someone with more knowledge could help us less tech savvy individuals 🙂

Don't let anyone confuse you. When you are just using an external display, first try the normal way. nVidia cards are very easy in Bootcamp. You can read some steps up here: Step-by-Step-Guide. If this doesn't work, try to find similar setups here Build-Guides

And if it works, make some nice benchmarks with your Titan Z! I am very curious.

@mac_editor, @itsage, do you see? This is a very easy setup, 15" MPB 2016 with an nVidid card, external display is enough. This shouldn't do cause any problems in the first hand and what are they talking about? Disabling port 1905?! Really?

Well, I can say with 100% certainty that without disabling Bus 1905 I cannot get my eGPU to function in Windows 10 Boot Camp. This is with a 2016 15" MacBook Pro, which I've read Windows has issues allocating resources for. I used it for the last 3 days without issue and decided to try re-enabling 1905 to see what would happen. As soon as I did, nothing is displayed on my monitor. Device manager tells me there is nothing attached to this bus, so it is definitely a resource allocation issue.

There are some builds that seems to work on this model without disabling 1905, like e.g. GTX1070 Build. As said before, nVidia cards are quite resilient against Error 12. To be honest, disabling two TB3 ports is barely a good option.

What exact Windows Version do you have (with Build)? Did you try a fresh Bootcamp install?
