@ac2334, I was under the impression that nvidia cards always work straight out of the box

@arouris, me too, but I still ran into error code 12. Now, having reinstalled Windows from scratch and seeing that everything works, I can say that it was probably a misallocation of the port due to the fact that I have two thunderbolt displays attached to the imac. Once those are added after the egpu, all works fine.

Happy with this setup, egpu performance is decent enough but when I connect a 4K monitor via displayport it really shines

Cool

Doesn't work for me. Still getting Error 12.

What I've tried:

  1. Install latest Win10 ISO (May 2020 Update) in bootcamp
  2. Enable Windows Insider Fast and install latest Build 20152 rs prerelease
  3. Plugged in Razer Core before boot
  4. Get latest bootcampdrivers.com software (Red, from April)
  5. Run DDU with default settings, restart
  6. Install AMD drivers (1x with and 1x without factory reset)
  7. Radeon 5300 M works, 5700 xt throws Error 12
  8. Disabled the 5300 M, didn't change anything

Hi there,

Disable automatic updates, including drivers from updates.

DDU the AMD drivers in safe mode to start again. Don’t plug-in the razer core yet, install drivers first.

Once installed, turn off the machine and cold plug the razer core.

Switch on. Should work no problem.

N.b. I still use the Dec drivers, as the Apr drivers don’t work for me with some of the latest games like Gears 5.

@bully_82uk Hi, that didn't work either unfortunately. Still getting Code 12.

 

/edit

I also tried installing an old version of windows and followed these two builds step by step...

Hey guys, it’s been a crazy couple of weeks trying to make my EGPU to run.

 

i have a 2020 macbook pro 16” with a stock radeon pro 5500 and a razer x egpu + amd RX590 running on windows 10 2004 standard.

 

i was doing all the steps, DDU + red drivers from bootcampdrivers and at the beginning i was getting error 12, so i did the EFI hack as someone explained here and i got rid of the error 12, however now it’s giving me error 31 (windows cannot load drivers required for this device) so I uninstalled all drivers through DDU and installed again and i’m still getting same error. 

when i open the devices manager it does recognize my stock GPU (amd radeon pro 5500m) however the rx 590 still listed as Microsoft basic display adapter, running with microsoft drivers.

 

anyone could give us some help?

happy to pay someone $50 AUS if you can guide us through whatsapp! 

going crazy here already 🤧

Out of curiosity I just tried the Windows fast insider build. Both hotplug and coldplug have worked flawlessly for 2 days.

2018 Mac Mini, Razer Core X, Gigabyte Radeon RX 5600XT.

2 x 4K monitors connected directly to the AMD GPU via displayport.

Windows build 20152.rs_prerelease.200617-1502

 Process

- Fresh install of the latest version of Windows 10 Pro using bootcamp

- Boot and setup system using the iGPU

- Update to insider build

- Hotplug eGPU, install AMD drivers

- Shutdown system, disconnect HDMI from Mac Mini, restart with eGPU connected to monitors only

- No other patches or stuffing around was required

Stock AMD drivers, straight from their website.

To join the Windows Insider Program, just search for "insider" from the windows search bar - it'll take you to the insider program screen. Just have to join from there and then select the fast setting.

I'm expecting that it could get broken in another update - might be worth disabling updates just in case.

@rak, a very frustrating time (I’ve been there, and not so long back)

a few queries for you;

  • Are you bootcamping to an external drive, or is the partition on your internal drive?
  • In regedit what update policies have you disabled - can you share a list?
  • Are you installing the bootcamp drivers via extracted folder setup or update to drivers within device manager? I know a lot of people recommend the latter but feel you miss out on some of the benefits of the Adenaline drivers such as image sharpening - makes a massive difference.
  • What port are you plugging the eGPU into? I don’t do the sacred port dance, but use the LHS ports. 
  • Have you checked Apple’s boot camp drivers are they UTD?
  • Did you give the Dec Bootcamp drivers a go?

Happy to help. You’ll get there!
