HI!

I ahve an iMac 2018 with an egpu vega 64 setup. I isntalled the Windows to an external ssd and I booted the Windows. I installed every drivers with the boot camp assistant and also donwloaded and isntalled the newest driver for the vega 64. When I try to reboot the OS with the vega 64 (hdmi from teh card) after the windwos logo I see only black screen. In the device Manager it says error 12 It has not enoguht free power or something (hard to translate from Hungary).

I read some topics from ehre but all was so difficult and I dont't rly understand them.. maybe any video or an easy step by steap method to fix the problem? 

Thanks guys!

Hello there, I’ve explored these forums and found different guides to solve code 12 on Macs, but I’m having trouble finding the guide to solve it for my 2018 13” MacBook Pro today, I know I’ve found it before, but can’t seem to find it today and it seems that each model has slightly different solutions so I want to be sure I’m doing right. Help would be appreciated as I’m in desperate need of it to get a Vega 64 working in Bootcamp. Previous graphic cards I’ve been able to live with not having my internal display working by leaving the eGPU plugged in at boot, but now my Vega 64 isn’t powering my external display at boot so I’m left with a pretty expensive paperweight that works fine in other computers (my dad tried it in his desktop and it works great) and under macOS but not Windows. Any help would be appreciated!

I read your post on a different thread (the one with update 18362.329). I assume it's regarding your (A) build?

Right now, it seems that the only stable windows version for an eGPU setup with your type of card is downgrading to windows 1903, ver 18362.295). Theres a lot of posts on how to downgrade to that version in that thread if you don't know how, and it's very important that you disable all types of automatic updates. Sometimes windows won't allow disabling these in the "windows update center". So you will have to go through the "gpedit" way. After you have done that, I suggest that you follow any detailed guide with a RX5700 in the build section. I usually have a lot of success following the guides by @itsage .

Edit: I just did a quick search on the builds section and found two builds with a MBP 13" and RX5700 XT. Although not the same case or MBP iteration (the second one). I'm sure it will work for your current setup. The second one is a bit more detailed than the first one (in case you need more details).

Thank you very much for that. 

yea it is for my A build. 

i have set up a new ssd with w10 1903 v1 Version. Initially could not get the gpu recognised. 
Now I can see the card but have the errror 12. i ll try disabling a pci port next.

i have tried the 1803 downgrades to summer update. I tried full 1909 with full 2020 updates as well as downgrade to original release. I tried 1903 with both full updates and downgrading to .295. That is why I think my next step will be the pci solution

Here's a work around I made for the 2015 MBP 15".  This method might work with some of the other MBPs as well, but you would need to change the driver IDs.

https://github.com/ppkantorski/eGPU-toggler

I have it set to run within the startup.  This lets me restart my computer from clamshell mode and have it automatically boot up to the login screen on my 21:9 monitor via the eGPU.  Its just a variation of the method that takes advantage of the toggle on and off approach for resolving error 12.  One advantage to this is having both discrete GPU's accessible.

So I may have done a dumb thing.

I ran the 10.15.3 update in macOS an its killed my egpu again. I previous had issues and had to recently reinstall 1809 (I think) and disabling auto updates to make it work.

I tried running the boot camp update that also popped up but still no luck. Error 12 all day 🙁

Was there something in the 10.15.3 update that killed egpu in bootcamp?

Setup is a 2015 15" running an 5700 xt.

Hello everyone,

Im trying to get a rx 5700 xt working in windows 10 bootcamp and I cant get it to run. It shows up in the device manager with a (code 12) error. It works just fine in macOS. Has anyone gotten this working? If so, care to share how? Im using a razer core x chroma, a 2018 mac mini i7, and the rx 5700 xt.

 

Thanks so much

Specs:

2018 13"  MacBook Air

XFX  RX 580  Black Edition 8GB

Razer Core X

MacOS Catalina 10.15.5

Windows 10 1903 Build 18362.30

Dell U2415 monitor

 

So I've been working at this for about a week now, banging my head against the wall. Error 12 actually comes and goes for me--sometimes I boot up and the external monitor works just fine along with my internal display, sometimes the internal display gets the weird windows logo flickery thing, sometimes nothing works at all. Without fail, if I boot up Windows and plug in the eGPU after boot, I will receive error 12. 

I've tried many, many things to avoid error 12. I've disabled the Facetime HD camera, disabled PCIe Root Port #9, used the EFI boot that egpu.io lists, but nothing seems to work. Any miracle fixes that people seem to like?

Edit: Forgot to mention, sometimes when I boot up the computer just straight up doesn't recognize the graphics card
