Lucy183 Posted April 4, 2018 Share Posted April 4, 2018 I have an Asus R7 250x 2GB which works in Sierra with WhateverGreen+radpg=15 OR FakeSMC with Verde patch, but in High Sierra isn't working. Whatever I try I get black screen on both DVI and hdmi, i can't test DP but I'm almost sure it's black screen too. I tried: WhateverGreen, FakeSMC with Verde patch, RadeonDeInit, editing AMDRadeonX4000.kext and disabling some power gating. Link to comment Share on other sites More sharing options...

If you have access to windows use GPUz and dump your GPU's BIOS and put it inside the ROM folder under /EFI/Clover/ROM and test with RadeonDeInit and see if it helps. for more info you can check this topic. If you don't have access to windows you can use dpcimanager and dump the GPU's ROM. 2 Link to comment Share on other sites More sharing options...

You don't need to use Load VBIOS necessarily but you can test with and without. At first don't use that flag if that didn't work give it a try. 1 Link to comment Share on other sites More sharing options...
Lucy183 Posted April 4, 2018 Author Share Posted April 4, 2018 (edited) I tried with and without load vbios and isn't working, same black screen I can get it working under HS by rollback 10.12.6 kexts, but metal isn't working then and I need metal... Also I don't have iGPU or 2 PCIe to use nvidia helper card(Desktop from signature, except the nvidia replaced with R7 250x) Edited April 4, 2018 by LuCyr04 Link to comment Share on other sites More sharing options...

Cyberdevs Posted April 4, 2018 Share Posted April 4, 2018 (edited) That's weird, did you install macOS with the nVidia GPU plugged and then switched to AMD or did you clean install? if not I suggest you do a kext cache, nvram clean up and see if that helps. 4 minutes ago, Allan said: High Sierra broke the macOS sleep for many users.

As I mentioned before I never could get macOS High Sierra to work on my EP45-DS3R rig, it always end up in the black screen. I haven't tested the 10.13.4 though but I just assumed that it wouldn't work either. I might give it try later and if I succeed to boot into macOS I'll let you know. But as far as I know R7 250X doesn't have a UEFI BIOS itself although it can be UEFI compatible but there is no point of doing that I think since your mainboard doesn't support UEFI anyway. I have an Sapphire 7790 with legacy BIOS which I modded the BIOS to be UEFI compatible and I will test that later on and see if it does help or not which is highly unlikely.

Cyberdevs Posted April 4, 2018 Share Posted April 4, 2018 Well if GPU-z says it has a UEFI BIOS then it definitely has the UEFI BIOS. I'm not sure if you can find a Legacy BIOS for your GPU or not (everything is possible in the tech world though) but be careful with flashing your VBIOS you might end up bricking it.

Cyberdevs Posted April 4, 2018 Share Posted April 4, 2018 Well I guess the previous owner might have modded the BIOS. if you are sure about that you can find the OEM BIOS for it and flash it back to the factory settings. But be cautious and make a back up of your existing BIOS before flashing it. Link to comment Share on other sites More sharing options...

So I have no change to get it working without helper card under HS? Link to comment Share on other sites More sharing options...

Have you tried to edit the AMDRadeonX4000.kext?

Actually on Sierra without disabling power gating it gives me a red glitchy screen with cursor, but on high sierra the screen is completely black.
