Error 12 is no longer a thing !
Windows 10 - 20H2 Version is a blessing !
hope this will sort out the performance issues I used to get about my i7 8700k CPU on windows.
what 20H2 build are you using?
- @hans-st, I’m using the 19042.685 build.
I couldn’t access the windows version update by my windows settings it would only give me the 1909 so I used this link microsoft.com/en-gb/software-download/windows10ISO
Awesome! I used the above 20H2 build and for the first time I was able to get my Razer CoreX Chroma/RX 580 working with my 2018 15" MBP in bootcamp! No messing with EFI and disabling System Integrity Protection. Awesome. All I had to do was install the above build, run DDU and install the Red drivers from bootcampdrivers.com
I did still get error 12 after a while, but resolved it with the registry hack from https://egpu.io/forums/bootcamp/mbp-2019-late-razer-core-x-amd-rx-5700-xt-hackflags-0x600-worked-for-me/
