System specs

MacBook Pro (15-inch, 2019)
Processor: 2.6 GHz Intel Core i7-9750H
Memory: 16 GB 2400 MHz DDR4
Graphics: Radeon Pro 555X 4096 MB
Intel UHD Graphics 630 1536 MB

eGPU hardware
Enclosure: Razer Core X
GPU: MSI Radeon RX Vega 64 Air Boost 8G OC
Cable: 0.5m TB3 cable (came with enclosure)

Installation steps

A. MacOS 10.15.1 

Pretty straight forward, literally plug and play.

B.Win 10 1903 (build 18362.30)

At first I had the Windows to go inside a samsung T5 SSD but it was a disaster lol. I know it is too dumb for me to hot plug eGPU in bootcamp windows environment but I never thought my display would went black instanly and my windows OS was dead lol. I tried to reboot in recovery mode and try to fix the OS but nothing can do. So I created a bootcamp partition in internal SSD drive instead and here are the steps.

  1. Clean install Windows 10 1903 
  2. Download Adrenalin November 2019 edition at https://www.bootcampdrivers.com/
  3. Reboot windows in safe mode without internet
  4. Run DDU inside the bootcamp driver folder, choose "clean and restart"
  5. After reboot in normal mode, run setup.exe inside the bootcamp drivers folder
  6. hot plug eGPU 
  7. if Error 12 appears, reboot
  8. done


I dont have any external monitor (yet) but I got a pretty solid 60fps in battlefield 4 with ultra settings and native resolution (2880 x 1800) 

and I went through some Heaven benchmarks


I bought this brand new Vega 64 in a great price (~$250), really nothing to complain about it but it is just way too noisy than I expected haha.

My ultimate goal is to build a desktop replacement workstation so I am planning to buy an external monitor, keyboard and mouse. With the external monitor, the performance can be further increased for 10-15% I think. Keep you guys updated when I get the monitor (um maybe next year lol).

I can confirm the above steps worked like a charm. It's confirmed you'll need to stop the updates and so far 1903 works better than 1909 on a setup running internal display on a macbook pro. Took awhile to figure out that I needed to individually assign the games to run a max performance to force them to run on the eGPU but all ended well. I'm running a Macbook Pro 15 inch 2018 with bootcamp windows and Razer Core X with a Asus Strix RX5700 XT.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Did you manage to get it working on an external monitor in the end?
