R9 390 8gb issue 7mb Bigsur!!

[Polyman]

help!! I have issue with AMD GPU R9 390 8GB shows 7mb
try many method with gpu-spoof fake id and Device properties also without
on different macOS versions Monterey,Bigsur,Catalina,Mojave all same problem also try many SMBIOS imacpro1,macpro6&7 same issue
its been month I try it shows audio gpu but no display
cpu AMD Ryzen 5 2600
I attached my EFI folder if anyone can fix this

Try this EFI in place of your current one.

1. I have cleaned up your config.plist - removing some unnecessary entries, including most of the DeviceProperties you added.
   • The Spoof SSDT should cover these aspects, all the DeviceProperties will do is conflict with or make the SSDT not work correctly.
2. I have changed UEFI >APFS > MinDate and MinVersion to 0, as you are running Big Sur and I assume will upgrade to Monterey at some point.
3. I changed Misc > Security > SecureBootModel from Disabled to Default, as this is the expected condition when running Big Sur or newer.
4. I removed two unused Tools.
5. I have added two kexts, RestrictEvents.kext and AppleMCEReporterDisabler.kext, as these are normally required in an AMD Hack.

Use this EFI from a spare USB pen drive.

Let us know if it makes any difference to how the AMD GPU works.

OK, try this EFI folder.

I have updated RestrictEvents.kext to v1.0.6, you were using an older version (v1.0.0). Hopefully this newer version of the kext will help.

Can you post a copy of your IOReg so I can see what is happening in your system regarding the AMD GPU.

How to Make a Copy of IOReg (Note 1)
1. IORegistryExplorer/File/Save a Copy As…. (no extension required)
2. Open file to verify (Note 2)
3. Attach to post (Note 3)

Installation
1, Open Downloads/IORegistryExplorer-SLRID_v10.6.3
2. Drag IORegistryExplorer to Applications

Notes
1. An IOReg.txt is not useful. It is not a "Copy of IOReg." Do not attach .txt files.
2. IOReg must open the file. If TextEdit opens, See Note 1.
3. Zip/compress the IOReg file (right-click select Compress....)

Use the version of IORegistryExplorer attached below. Don't use a newer version as they tend to corrupt the IOReg when you save a copy.

still same issue 7mb didn't work
here my IORegistryExplorer I use the one you attachment
and if you want I give you full access to remote with TeamViewr just DM

@Polyman You either need to use the SSDT or inject the values under device properties, don't use both methods.
Try these EFI folders and see if that helps.

hi thanks for reply i did before separately many times didn't work
i use your device properties keep stuck in boot

also there something in Device properties
if i add this device_type on GPU APCI root
it will stock on boot blackscreen
never get in os

still same stock on boot screen
i did this before many times i extract my gpu pci device from hackintool put device_type VGA compatibile
keep stock on boot won't get os

Boot into macOS with the config that works; Use OpenCore Configurator to open the config.plist, navigate to Device Properties and remove all the items in the list and then add all your device properties form the list like shown in the picture.
Save the config and post it here so I can check the address for the display adapter,

not working stuck in boot
bro I told you adding this device_type on GPU won*t get in OS stock on Boot

 

[Edhawk]

@Polyman are you using the ClearNvram and ResetSystem tools (available by pressing the Spacebar while on the OpenCore boot screen) between these EFI folder changes? As some of the Nvram settings may get carried over from booting with a different EFI.

Ok i just removed the device_type entry.

yes i did use before same issue nothing change

same issue i did all this before
give me other soultion

@Polyman
I use the same method to activate my R9 270 GPU, I don't use any bootflags so try removing these flags from the NVRAM section i the config:
raddvi radpg=15
After removing these flags reboot the system. reset the nvram and boot into macOS and see if anything changes.
