Guide How to Patch AMD Framebuffers for High Sierra using Clover

[dd93]

One of the DVI_D and DVI_D probably combine into one port.

Hiya friends, I have a MSI RX480 Gaming X 8GB (2x DP, 2x HDMI, 1x DVI-D) but the DisplayPorts won't do anything. I've been digging through these framebuffer topics, but I'm stuck regardless whether option I input, the card works fine except for the DP ports. This is on 10.13.6

From this I made the following Orinoco FB patch:

It doesn't seem to matter whether I inject any properties, or use Whatevergreen.kext, or even inject ATI besides RadeonDeinit, the result is the same.

Screens, connectors, and cables are tested and working on Windows the the rest of the machine:
X299-Deluxe
i9-7900X
32GB DDR3-3000

2x HP E231 1080p (DVI or DP, testing HDMI with DVI<>HDMI adapter).


Hope I supplied the right information for a pro to figure this out

Try this slightly modified version of your config.plist :

@P1LGRIM Thank you!

I had exactly the same framebuffer patch before, but didn't see a change. I'm sure I must have set one of the Graphics sections flags wrong at that point, so I missed my chance.

Cheers!

I didn't change any patches.

Can anyone help me out? I followed the guide (thank you) and have my custom port configuration all set-up. I can patch any of the framebuffers and they work for my system, the issue is the color depth in High Sierra. I am getting color banding, bad gradients, my system info reports 24-Bit Color. It's a mobile amd card, R9 375x, using Buri framebuffer with custom port patching:
0004 0000 0403 0000 0000 0100 0000 0000 2205 0404 0000 0000 eDP
0004 0000 0403 0000 0000 0200 0000 0000 1102 0101 0000 0000 DP
0004 0000 0403 0000 0000 0300 0000 0000 2103 0202 0000 0000 DP
0004 0000 0403 0000 0000 0400 0000 0000 1204 0303 0000 0000 DP

I have been looking around for hours trying to find a resolution.. but can't seem to fix it. Any help would be awesome! I am not using Lilu or whatevergreen; I am just using verde.kext for the cape verde power gating fix.

Thanks for a great guide!
I finally got my eGPU (STRIX gaming RX-580 with orinoco FB and custom connectors layout) working somewhat - showing a screen.

The issue I have is that after about 20s of login, the screen goes blank and powers down. Not sure what might be causing that issue. Anyone have any thoughts?

Are you using the eGPU over usb type-c thunderbolt 3? It's possible power management isn't setup correctly. I just know that the thunderbolt usbs are configured differently then the normal usbs by mac.

 

[emlynb]

@firebat Yes - I am. Do you know of how they are configured? I'll start digging down that path now

Honestly I wouldn't know where to start :C Is it a desktop or a laptop? I haven't been able to get usb-c on my laptop working, but on desktops they work fine for me. I would just post in either the desktop or laptop forum that you're having power issues over usb-c and maybe Rehabman can help you out. He is a legend!
