[Solved] I have another problem: only in bootcamp windows has error 12.
first of all, I would like to thank this forum and its people.
i have two laptop, two eGPU systems.
first laptop is macbook pro - i9 2.4Ghz, AMD vega Pro 20 dGPU, 32G ram. I use macOS and windows both.
and, installed Windows on an external SSD using Windows to go. After I installed all the boot camp drivers, I deleted the graphics drivers using DDU and install bootcampdriver's custom driver.
second laptop is Thinkpad P50 - Xeon E3-1505Mv5, Nvidia Quadro M2000M dGPU, 32G non-ECC ram. i only use windows in this laptop.
i can use linux but, i only use in my server it. so, i cannot test with linux.
and, i have two eGPU systems.
and, HP + RX580 eGPU is can use in any systems i have.
What's the difference between the two causing this problem? and, how i can fix this problem in macbook's windows with radeon VII? i was follow DSDT override in this forum, but i cannot fix this problem.
i attach screenshot with in this post later. many thanks.
i already use DDU and reinstall bootcampdriver's custom driver...... i will try again. thank you!
i tried again, but it doesn't works... error 12 is Still shown. i will try reinstall windows.
