Gigabyte R9 390 in High Sierra

Hello,

 

I have problems by using my R9 390 in High Sierra.

In Sierra my card is working well by doing the steps which Si Vis Pacem wrote hear.

http://www.insanelymac.com/forum/topic/315027-amd-r9-390-framebuffer-issue-on-1012-sierra/?p=2292376

Except that I don't activate Enable AtiInjection and don't force Framebuffer.

 

In High Sierra I tried the same procedure but the displays aren't showing anything except a black picture.

Tried only one Display at DP,HDMI or DVI but doesn't work neither.

 

In Sierra I can use my displays both attached to the R9 390 at DP and DVI.

 

Do you have any ideas what I could try?

 

Greetings

 

 

Hello MaLd0n,

 

thanks for you answer.

I followed your thread: http://www.insanelymac.com/forum/topic/322164-guide-sierra-high-sierra-on-gigabyte-ga-h97m-d3h-dsdt/?p=2391798

so I used your files you attached in an Clover.zip file. I don't know if the lilu and WhatEverGreen kext in this package are the newest.

Going to look for it and replace them if there are newer versions available.

I tried another method which works for another user's MSI R9 390 GPU:

I got the same result like I already mentioned in post 1 of this thread.

 

By searching I found a post about the patching of the FrameBuffer for my graphic card by another user.
But I don't get how to use these values correctly.

Which values do I have to use?

Because the values in bold are differing from the values in table style.

 

The table style are also less then the values which are mentioned in the tut:
