Radeon Compatibility Guide - ATI/AMD Graphics Cards

[Scott1204]

It was done in Sierra using slot one Nvidia and slot two AMD. The Nvidia acted as a helper card and ran on default drivers, but it was enough for the AMD to work. In Windows the Nvidia starts up and the AMD site in the number two spot. Don't know if it will work in High Sierra.

Thanks. So monitor is plugged into Nvidia and AMD is doing all the work? Is that the idea?

Does it allow the AMD to run full featured e.g. 4K resolution display?

If so, that would do the trick

Actually, the Nvidia would be your clover boot screen and at log inn the AMD will take over. So usually one monitor cable to Nvidia helper card and one for AMD for main usage.

Ok cool, will give that a try

Maybe it's Framebuffer assignment? Futomaki, Hamachi?

I already tried it, my Sierra set up works without any problem only with High Sierra it will not see my second screen.
I hope it it is fixed in the release tomorrow

Yes, use them. Someone recently set up this way and got HD8xxx 8gb. Let's hope it works.

Hey Gigamaxx...
I finally got around to swapping my R9 390x back into my system and trying your suggestion. No dice...unfortunately! Ugh...
It will boot with the iGPU selected in BIOS..but once I get into Sierra it won't let me switch to the 390x...
Oh well...I think I have exhausted all avenues here...let me know if you have any ideas
Like always..I appreciate all the help. Too bad since this is a really nice graphics card...

Anyway...take it easy...

What is The device ID? 0x????1002. Try fake ID 0x68101002 in clover boot manager screen, don't inject ATI.

If you have latest lilu & whatevergreen in efi/clover/kexts/other it should work out of the box, no injection needed

Thanks for reply me. I didn't change anything, only upgrade sierra to High Sierra.
