@mac_editor, Hi, I am using windows to go and strictly followed the procedure you offered. However, I  am unable to reboot the windows with egpu plugged.  Could you please give some advice?


MacBook Pro 15 inch 2016 (AMD Radeon Pro 455)

Razer core x
AMD Radeon 5700XT
macOS 10.15.4
Windows To Go 1803
Samsung SSD T5 500 GB


This afternoon, I tried the exact same procedure (win10 18362.295 build+bootcamp driver 2019 sep) and directly install win10 to bootcamp instead of WinToGo. Although, I could boot into win10 with egpu plugged in, it still rises error 12 (not enough resources). Could anyone help me? Thanks in advance.

@chenlin_lu, this thread is for 2018 MacBook Pro - see builds for your Mac instead.

I got Razer Core X and 5700XT and have a really poor performance on Catalina .3 .4 and 10.15.5 beta.

Also i got right now working on windows 10 but hoy to modify pcy.sys? i cannot find that guide.

Also, do you have enough performance in Catalina? before 10.15.3 i only see used 30% of it while doing a big rendern.


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