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
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.
