Problems getting a R7 240 to work

[edonkey]

I'm back again with another and last problem (I hope lmao).

This is my GPU

I've tried to follow this forum thread and also this one but with no success.

Using hackintool, I see that the GPU device id isn't changed(?)

My config.plist looks like this

and the ssdt I've used (the path of the graphics card is /PCI0@0/AppleACPIPCI/GPP2@1,3/IOPP/PT02@0,2/IOPP/PT24@4/IOPP/GFX0@0)

DefinitionBlock ("", "SSDT", 2, "DRTNIA", "AMDGPU", 0x00001000)
{
    External (_SB_.PCI0.GPP2.PT02.PT24, DeviceObj)
    Scope (\_SB_.PCI0.GPP2.PT02.PT24)
    {
        Device (GFX0)
        {
            Name (_ADR, Zero)  // _ADR: Address
        }
    }
}

In order for anyone to be able to help, you need to provide the following:

1. Post a copy of the SSDT you created, both disassembled and .aml versions.
2. Post a copy of the Hackintool > PCIe > Export - pcidevices.plist
3. Post a copy of your IOReg, use the version attached below.

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 as a zipped/compressed folder

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.

Hey sorry for the waiting, I wasn't available, here you go.

 

[Edhawk]

I have created an SSDT, which I have attached below. This SSDT-GPU-SPOOF-R7-250X.aml should work with your system to spoof the R7 240 discrete GPU.

Try it in place of the SSDT you are currently using. See if it work.

Just tried and unfortunately it still does the same thing

 

[Edhawk]

What other ‘fixes’ have you tried?

Did you remove the failed ‘fixes’ when it became apparent they didn’t work?

 

[edonkey]

The first thing I've tried after the install was this guide https://dortania.github.io/Getting-Started-With-ACPI/Universal/spoof.html , but nothing changed.
Then I began searching other methods and used the one mentioned in the first post and replaced the other ssdt for spoofing the GPU, but using that nothing happens and only the name of the GPU in the system information changes.

 

[edonkey]

This was the ssdt I've used

 

[Edhawk]

Are you using the config.plist DeviceProperties entry to spoof the device ID AND the SSDT-GPU-SPOOF.aml?

The two should not be used together, use one or the other not both.

Your IOReg shows two GFX entries. GFX0 and GFX1.

• GFX0 shows a Radeon R7 250X attached in Slot-1
• GFX1 shows a Nvidia GTX 1660 attached in Slot-2

Are you using an SSDT-Disable-dGPU.aml for the Nvidia GTX 1660? Is it set correctly to disable the GPU in slot-2?
The ACPI address for the GTX 1660 is (/_SB/PCI0/GPP8/GFX1), its that the address your current SSDT-GPU-DISABLE.aml uses?

Try this SSDT-GPU-SPOOF.aml the ACPI address has been extended to include the GFX0 part of the address, which was missing from both mine and your previous SSDT's. See if that works any better. Remember to remove the DeviceProperties for the GPU spoof when adding this SSDT.

I have also attached an SSDT-GPU-DISABLE.aml, that should disable your Nvidia GPU when running macOS.

 

[edonkey]

Yes I've made an entry in DeviceProperties when I've tried the second solution as you can see in the first post, the 1660 was disabled and that's not a problem fortunately.
I've just tried the new aml you sent and right now in system info it shows the default gpu name as before (yes I've removed the property in config.plist).

I'll also send the ssdt for disabling the gpu that I was using.

 

[Edhawk]

Maybe you need to talk to @Cyberdevs he seems to be fairly good with SSDT patching/spoofing etc.

 

[Cyberdevs]

@edonkey
Remove the device properties entry for the GPU and try this SSDT:

P.S.
What is the model of your GPU exactly? I mean which brand?

 

[edonkey]

Just tried and nothing changed, I have an oem card from an hp computer I had laying around

 

[Cyberdevs]

It's a little bit tricky since I don't know the exact device ID for your GPU is, I just can't find the best matching fakeID for it so we have to try different options.

 

[edonkey]

still nothing unfortunately, if you're wondering what the gpu looks like https://www.ebay.it/itm/302750016741

 

[Edhawk]

I think this is a copy of the GPU-Z information for the dGPU

Ven/Dev ID 0x10026611

[Cyberdevs]

ok try this one:
Also add radpg=15 (and -radcodec might not be necessary) under nvram section. Do a nvram reset before booting into macOS by pressing the space bar in OpenCore GUI if the nvram reset isn't available by default.

 

[edonkey]

Nope still the same and reset nvram too, also I always had radpg=15

 

[Cyberdevs]

@edonkey
another approach is to add the FakeID under the Device Properties instead of using the SSDT like in this example:
