@itsage, I have tried such disabling all TB3 ports except the one required but it never boots with egpu, do I have to ddu it before attempting? Btw thank you so much for your assistance.

@e_wong, The way I understand Windows resource allocation is that once it assigns a particular PCI Express Root Port with a significant amount the other roots will be limited. DDU removes the graphics drivers as well as this PCI Express Root Port association/allocation. Therefore we should run DDU every time we want to switch Thunderbolt 3 port.

@itsage, so the process would be

1.DDU

2. Install AMD drivers with factory reset option selected.

3. Shut down the computer instead of selecting restart prompted by the installer.

4.Restart the computer.

 

Thank you so much for your help. Smile

 

 

Edit:

This didn't work, only the TB3 port closest to the tab key worked.

@itsage, I've done another new fresh Windows install via bootcamp, disabled auto updates and didn't even connected to WiFi just installed DDU and AMD Adrenaline drivers 20.4.2.0 from offline setup files.

 

Still getting error 207 at the end of the AMD drivers setup. I've tried DDU and selected factory reset in AMD drivers setup many times without luck.

I've also tried keeping the egpu connected during windows startup. Keyboard freezes for around 30s at Windows log on screen (someone suggested it's a good sign as Windows is allocating resources for the gpu) then Adrenaline setups resumes but at the end I still got error 207.

Which version of Adrenaline drivers are you using? I've got Sapphire 5700 XT Nitro+ limited edition card. 

 

Thanks

@kobazik, I'm using the latest 20.4.2 gaming drivers downloaded directly from AMD website. If you see the RX 5700 XT eGPU in Device Manager, maybe do a manual driver update through right-click and point to the Radeon drivers folder.

@itsage, just tried it and it says the drivers are already the latest. Would you mind sharing a screenshot of drivers details of your 5700 XT? Here is mine https://imgur.com/gallery/lrijyD8

I want to make sure I'm not using Windows drivers for some reason even after DDU and while being offline.

 

Thanks

@kobazik, Mine is the same version as you have. You can try the uninstall button inside Device Manager and do a manual driver update/install from there.

@itsage, finally got it to work! Thanks so much. Someone mentioned disabling the iGPU - did so, restarted and the eGPU was detected and usable, afterwards I could enable the iGPU again and everything was working properly.

@itsage, ok so I've tried disabling facetime camera and broadcome WiFi adapter in device manager, then disabled first PCI root bridge and enabled the second one. I've contacted egpu to the second thunderbolt bolt on the left, driver installation failed again with 207 error. Then I've shutdown and kept egpu plugged. After reboot it works! Not sure which bit made it actually to work.
