MSI RX 580 armor oc 8gb black screen on Mojave

Recommended Posts

Hello everyone,

I bought the MSI RX 580 armor oc 8gb and at the end of booting sequence, the screen turns black. I bought it because it thought it was going to work OOB, but nothing

This RX 580 card has 2 x HDMI, 2 x DP, 1 x DVI-D

System configuration:

Mac OS 10.14.6

Motherboard: Gigabyte H55M-USB3

Processor: i5 760 @2.80 ghz

PSU supports up to 600w

Clover 5119 (also used 5102 before, but the result is the same, clover version doesn't seem to matter)

 

VERY IMPORTANT: I also have an Nvidia GT 210, using it plugged in PEG 16x and the RX 580 Plugged in PEG2 8x, I am able to boot the system, but only using -x flag. So no hardware accelleration on both cards, however I am able to use any of the port on the RX 580 (2 x HDMI + 2 x DP). At least, in this way, I understand there should be a way to have the RX 580 work. If I don't use -x or if switch the cards, (RX 580 in PCI 16x and GT210 in PCI 8x), I get gioscreenlockstate 3 hs 0 bs 0 now 0 sm 0x0, which seems to be due to some kind of error in High Sierra, but I found that it was solved after, and since I am in Mojave, I have searched a bit more and it seems it's due exactly because of 2 GPU at the same time. The funny thing is that when I am able to boot with -x, I plug both cards to the same Samsung TV via HDMI, without mirroring the screen, the GT210 has no accelleration, but when I change HDMI port from my remote to see what is the RX 580 doing, I have maximum resolution. 

I have tried many things, like:

1. Lilu 1.4.5 + Whatevergreen 1.4.0 (right now these are the lastest versions), no Ati Injection, no RadeonInit

2. No Lilu, no WEG, Ati Injection, Orinoco Framebuffer with 5 ports

3. I tried the guide on how to patch AMD FB, but i guess something was wrong when dumping RX 580 Rom using PAVO's script. The 8 digits blocks are positioned in a different way compared to what I saw in the tutorial. I don't know if I can make any reference to other sites. (See attachment AMD_Framebuffers_Extraction.zip). I patched all the framebuffers with 5 ports, created different config.plist for each framebuffer and booted each one from clover bootloader. The result was the same

4. I have tried all ports with all these methods, none is working.

 

Please, let me know if you need more informations, files, screenshots, videos, whatever could help you to help me.

I tried every output. Both DP outputs just return black screen like HDMI, but if I am in safe mode (-x) with the GT210 in x16 PCIE slot, I can get full resolution and all ports working for RX 580, even if there is no accelleration like QE/CI, Metal etc. It's really strange. I also checked the loaded kext, and AMD9500controller is loaded when I am able to boot using -x.

Type corrected (AMD instead of HDMI)

Thanks for your answer. Finally I was able to boot without -x and with only the RX 580. I injected EDID using 1002 for vendor and 67DF for product and both DP and HDMI are able to get to the desktop. I will make few checks to see if everything is ok, but for now the legacy MOBO is accepting it. I will report back later with more details

After few checks I can confirm that there is no metal support and no video acceleration. Any solution?

Thanks for your effort, but I still get the black screen since there is no inject edid and vendor 1002 + component 67DF

This is the efi folder with which I can get to the desktop, even if there is no acceleration

Edit:

- Now I am able to boot without having to inject edid, vendorid 1002 and productid 67DF after doing the following, but still no acceleration:

- Change SMBIOS to iMacPro1,1
- Applied Graphics Policy patch in config to overcome black screen on boot issue.
- Added dummy kext in the kexts/Other folder.

 

I will try to use some of the bootflags in the config.plist you created for me and see what happens.
