[Success] AMD RX6000 Series working in macOS

[aka80]

Me too, if it was a setup issue others would have encountered this issue. The fact no one else using the same series GPU is talking about coil whine is telling.

Hi guys,

Thank you for your reviews and feedback.
I have since returned the board, and this time ordered a brand new RX 6600 which I received and tested today. On this model I have no whistling or coil whine. We hear slight noises when I'm on safari, but nothing bad. You were right, it was a card issue.

I did some tests with Geekbench 5, and with Metal I'm at 78000, and 58000 with Open CL.

But I still have my login screen which goes black for a few seconds, and recovers the normal display. What do you think this phenomenon is due to?

thank you to all of you

GB 5 scores are ok.
On my hack, I see the OC picker >> the Apple logo and the progress bar >> at around 30% of progress bar the screen goes black >> after 4-6" I see the Desktop. Are you talking about this black screen?

Yes I think it's the same thing. But on my hack, the screen goes black for a few seconds and comes to back normal (with the display of the screen resolution indicated, as if we had switched to a new hdmi input), when I get to the login page.

HI @zappy39 very thanks for help man, great idea!!! Thanks a lot!!!

Nice Metal scores, are you running the Gigabyte Auros 6900XT (XTXH variant)?
If so, I'm running the exact same card. However, my metal scores are 170K.

Another thing I noticed is my GPU shows up as AMD Radeon HD GFX10 Family Unknown Prototype under Hackintool. Is this purely cosmetic or does it affect performance?

Thanks.

Upload here the config.plist file (remove serial numbers) and paste the code of your SSDT-BRG0. What is the IOReg path to the AMD? Get it from Hackintool.

Hi, thanks for the response, see attached.

Code:
DefinitionBlock ("", "SSDT", 2, "ACDT", "BRG0", 0x00000000)
{
External (_SB_.PC00.PEG1.PEGP, DeviceObj)

Scope (\_SB.PC00.PEG1.PEGP)
{
Device (BRG0)
{
Name (_ADR, Zero) // _ADR: Address
Device (GFX0)
{
Name (_ADR, Zero) // _ADR: Address
}
}
}
}

Hackintool:

Thanks
EDIT: Also just to add, in Hackintool under System --> GFX0, the GPU Device Id states 0x73BF1002, is this right?

I think I'm going to return it and see if I can find a non-variant card for a reasonable price. But for some reason the XTXH cards are like $300+ cheaper despite being better performers.

This was the way out for me... got a non-XTXH variant (the XFX SWFT 319) and it worked out of the box. Didn't even need to add names to the device path with an AML.

No. Have a look at mine. The deviceid for a 6900xtx should be BF730000.

In my Config.plist it's BF730000. However Hackintool shows it as 0x73BF1002.

Can you confirm what yours says?

Also how do i fix the Metal Device Name?

Thanks

@Sabzz
I think that the device-id is the same in Hackintool and in config.plist, 1002 is AMD but we don’t set it in the config file. The hex pairs are swapped, maybe Hackintool displays it in this way.
How do yo see it in System Profiler >> Displays?
Or by gfxutil in Terminal?
The metal device name, if it is ok in System Profiler or About this Mac, I don’t care, Hackintool looks at its own database and maybe the XTXH is not included.
