Radeon Compatibility Guide - ATI/AMD Graphics Cards

@Fl0r!an
280X Saphire under El Capitan need IGPU enable like Sierra?
It's the only way I have to get desktop after black screen.

I checked and unchecked NO inject ati and any framebuffer or ID in config.sys

Anyone having color flashing issues with 10.12.4?
AMD Radeon HD6790 with modified Info.plist on AMDX3000 and AMD6000Controller, was working perfectly with 10.12.3.

@Ur-Quan said "setting RGBA8888 mode can solve this", worth a try!

No. ATI 5450 is completely in Sierra. You can try injecting ATY via a DSDT or try Inject EDID. Attach all files on [Guide] Enabling ATI Radeon HD 5450 thread.

@cyberdevs: Guess you might need to make your own framebuffer personality than, based on the physical port layout of your GPU.

@budafilms: R9 280X doesn't need iGPU in Sierra for basic functionality & acceleration (at least last time I checked, didn't update to 10.12.4 yet).

@Flor!an

My Sapphire 7790 specs are:
1 x DVI-I
1 x DVI-D
1 x HDMI
1 x DisplayPort

which is working with the following settings:
Dual Link is set to 1, FB Name is set to Baladi, VRAM is set to 1024, Video Ports is se to 4, Load VBIOS is checked and finally Inject ATI is checked too.

Under Kernel and Kext Patches:

ATI Connectors Data is set to:

000400000403000000010300120403030004000004030000000101001102010100040000040300000001020021030202000400000403000000010400220504040004000004030000000105001000050500040000040300000001060020010606

and

ATI Connectors Patch is set to:

000800000400000000010300220503030004000004000000000101002103010200040000040000000001020012040201040000000400000000010400010204040400000004000000000105000000050600040000040000000001060020010605

and finally Ati Connectors Controller is set to 8000


and My HIS R9 390X are:
1 x DisplayPort 1.2 - 4096x2160
1 x HDMI - 4096x2160
2 x Dual-link DVI with HDCP - 2560x1600

The thing is I plugged the second display to DVI-I on my sapphire graphic adapter and it works but the HIS graphic adapter only has DVI-D.

So where do I go from here?

I found by mistake a way for not have enable IGPU and black screen with 280x on Sierra.

I made a partition in Sierra for test Final Cut X on El Capitan, because I read that work faster than Sierra.

I installed El Capitan. Set mobo NO IGPU, just PCIE.

I turn on the computear and in Clover Menu went to Sierra and no el Capitan. And I'm in without black screen.

I hope this going to be usefull.
