Installing NVIDIA eGPU under Windows 10/11 on Mac Pro 6,1 (2013)
This guide only works with our specially eGPU flashed MacVidCards cards for Apple Mac Pro 6,1. Use this guide too if you need to update drivers for your NVIDIA eGPU.
Connect your eGPU to the Mac Pro 6,1 (2013), but do not connect any displays to it yet. Use built-in HDMI port inside Mac Pro to connect the display for the installation.
Please note you cannot hotplug eGPU under Windows in Mac Pro 6,1 (2013). In order for the eGPU to be seen you need to plug it before starting the computer.
Also when there is eGPU connected (or any other Thunderbolt 2 device) sleep and resume modes are disabled.
Step 1Card will be detected automatically, but we need to install the latest drivers first.

Step 12Now it's finally time to reconnect your display from the integrated graphics cards HDMI to the eGPU (there is no need to turn off your computer to do this).
Remove the HDMI cable from the HDMI port and plug the display (or displays) to your eGPU. We recommend DisplayPort (or miniDisplayPort) depending on what type of ports does your eGPU have.
Connect OWC NewerTech HDMI Headless 4K Display Emulator (or other brand) to the built-in HDMI inside Mac Pro 6,1 (2013).
That's it. Your new eGPU is now fully working.
WARNING: When you start your system with OWC HDMI dummy display HDMI plug inside Mac Pro 6,1 (2013) there would be no Windows splash screen.
You will see something on screen right before desktop is loaded. It's because the computer is using the first (dummy) display to display Windows logo and there is no way to change this. The second display (the one connected to eGPU) is activated as soon the display driver is loaded.
If you have multiple Windows versions installed (or other OS like Linux) you will see Windows boot manager as always.
We recommend setting default startup disk to the BootCamp (Windows) partition.
Then if you need to boot to macOS you can either remove OWC HDMI dummy display plug and see normal Apple boot screen or you can choose an option Restart in macOS. |
