Hello everyone,


First of all thanks to all the persons that are sharing their knowledge and experiences about making an eGPU alive on tricky hardware setup.

That is why internet was made for Grin




I’m trying to setup an eGPU configuration with the followings hardware:


Mac mini 7,1:

- Year 2014

- iGPU Intel Iris Graphics 5100

- i5-4308U 2.80 GHz

- macOS High Sierra 10.13.6

- Bootcamp Windows 10 (1607 and 1809)


Akito Thunder 2 PCIe Box

EVGA GTX 1660 Ti

Dell Power Supply 220W to Power eGPU + Akito Case

Apple Thunderbolt 2 cable

Acer 24" LED - GN246HL as external display (HDMI/DVI-D)



I did follow few different post in order to setup my eGPU:





None of these one worked for me, but I will details which step I did in order to give the most inputs I can if someone want to try to help me Smile



This is all the step i did before writing here

  1. Fresh install os macOS Sierra 10.12.6 on the Mac mini (Debian 9 was installed before), then update to macOS High Sierra 10.13.6.
  2. Installation of Windows 10 1607 via Bootcamp assistant
  3. After installation, installation of Bootcamp Windows support
  4. Downloading the right Nvidia Driver (430.64 at this this I write the post)
  5. Before running updates, try to HotPlug the PCIe Box, the card wasn’t recognized (Microsoft Basic graphic cards)
  6. Running the windows update (Took me like 9000000 hours)
  7. Try to hot plug again before rebooting, nothing showed up
  8. Reboot in order to apply updates
  9. After reboot, hot plug the PCIe box, still not recognized (Microsoft Basic graphic cards)
  10. Shutdown
  11. Unplug the eGPU and reboot on macOS
  12. Run and scripts, and reboot on macOS again
  13. Hotplug eGPU: not recognized
  14. Shutdown, plug eGPU, start on macOS, still not recognised
  15. Reboot on windows again, still not recognized
  16. Reboot on macOS, the Akito 2 Thunder Box is recognised with a device plug in it but mark as unknown
  17. Unplug the eGPU
  18. Update macOS to Mojave
  19. Stil not mark as unknown in macOS and still get Error 31 on Windows


I don’t know what to to next, I thought it was cause of the Akito Thunderbolt 2 using PCIe 2.0 and the card is PCIe 3.0, but in the past I was using this box with a GTX 1060ti, which is PCIe 3.0 also, and it was working well.


Does any of you have inputs to help me ?


Thanks for reading
