Thank you for the reply.
All 6800 ans 6900 are Dual Link? Also, who know the right sequence of 0A AA AA 00 to be put into a SSDT?My own testing found that this is basically best results to get max performance and stability.

The injectors are a must. defining slot is optional but nice to do cosmetically.
Defining Dual Link also seems to matter a bit, and it's not a surprise, any AAPL injection is good because those won't exist on a card without a mac EFI, so making them present makes system profiler happy and also even system happier in terms of dual link (that seems to be a minor performance increase on top of correct frame buffers)
Device ID only if it's an XTXH card you need to spoof. do NOT add this if you do not need to change it
Lastly, device_type seems important to resolve some wake from sleep issues in my testing. The users who are getting black screen on wake might need to add this to solve that problem because without that also being set to correct ATY type, might be why wake is screwed up.
I also agree about not using sPPT. This also seems to cause some sleep issues, for me having these present caused random system wakes from the gpu. no real surprise that messing with card power management....messes with power management.
Oh and these were my 12.3 results using the exact above setup of values
I'd like to also add that I only have coffee lake cpu. no resizable bus support and PCI express 3.0.iMac19,1 - Geekbench Browser

It's the same Navi 21 core, so all should be dual link.All 6800 ans 6900 are Dual Link? Also, who know the right sequence of 0A AA AA 00 to be put into a SSDT?
how did you spoof it into W5700X ?All good here! Had to fix the Navi graphics issues and spoof my 5700 XT to a W5700X but other than that it went smooth as butter! OC 0.7.9View attachment 544460
I used this guy's method. Worked like a charm!how did you spoof it into W5700X ?
This can be fix easily by adding the following in the config.plist and reboot.

After reboot, it came back to 178k, it was 88k before applying the patch.

@Kalypso478 Do I need to first flash my graphics card BIOS before using this spoof ? I have a Powercolor Red Devil RX 5700 XTTested with my AMD Radeon RX 5700 XT 50th Anniversary. It works.
Why should you flash the BIOS of your graphics card? Good question, I didn't. Merely the property injection added.@Kalypso478 Do I need to first flash my graphics card BIOS before using this spoof ? I have a Powercolor Red Devil RX 5700 XT
