Radeon Compatibility Guide - ATI/AMD Graphics Cards

Dears, thanks does it is possibly to have a copy of it to add and make it at work?
I'm so close...

The R9 390X won't boot into Sierra without disabling pre-OS graphics (usually done by iGPU=Primary, not possible on X99 though).

I wouldn't recommend that card, since drivers aren't perfect either.

Thank you!

So running 2 R9 280X Sapphire video cards, running 10.12.4 OOB everything seems to run smoothly of course boot to black
Do I need to do anything to make Sierra use both cards?

Thanks

Good morning,
I did all but I am still not able to sort it out it is the ASUS ROG STRIX Radeon Rx 480 8GB OC Edition DP 1.4 HDMI 2.0 AMD Polaris Graphics Cards STRIX-RX480-O8G-GAMING. Same message to "append"...

I am adding the files I edited: what's wrong? I really don't understand what also to do...

@sev7en ,

There are dedicated RX480 threads that will help better...

Spoof device ID to R7 360X. If you're using Sierra, you'll most likely have to use iGPU=Primary.

Additionally, since it's an XFX card, you might have to use a different VBIOS. Most of this is covered in the first post of this thread.

I rolled back to El Capitan but i can't get it work. Now my graphics card will start after i got a black screen. I pulled off the connector and put i back in and than i the screen shows the login screen.

But i still get 7 mb and the r9 360 in about my mac. I found out my device id is 0x665F1002 this isn't in and7000controller.kext and not in the amdradeon4000.kext.
I tried to load another vbios no luck at all. I think ill give up.

I've added some screenshots and my config

Cheers Dennis

Spoof device ID to 0x665C1002, this is present in AMD8000 as well as X4000.

 

[unijhesk]

anyone had worked on Cayman PRO [Radeon HD 6950]??

 

[Fl0r!an]

Cayman drivers are present but broken, can't be enabled (Apple never used this GPU, so they didn't need to make a proper driver).

After installing Sierra 10.12.2, I was struggling to get Nvidia drivers working with a $300 Nvidia 980 GPU. I changed my plans and decided to try an AMD card. I put in a Gigabyte 7970 card (GIGABYTE Radeon HD 7970 DirectX 11 GV-R797OC-3GD 3GB 384-Bit GDDR5 REV 2.1 PCI Express 3.0 x16 HDCP Ready CrossFireX.)

I got this card for $100 on Ebay. The card was "plug-and-play" and was recognized over my DVI port immediately at boot with no fooling around and it runs my DELL U2413 @ 1920 x 1200 @ 60 Hz and Pixel Depth:30-Bit Color.

This was a very easy install, it just works. I don't need 4K or 5K. And this card rips through photoshop and video editing. GPU scores with Geekbench open CL 106,389 which is ample for my needs -- I edit 1080 video and do graphics -- no gaming here. I don't know if all 7970 cards are equally good, other manufacturers may vary but so far this is a great $100 solution.

Wake from sleep? I never sleep my system anyway. I have "put hard drives to sleep when possible" enabled in preferences. Other than that, my computer is off -- or on.
