Would you mind to tell me how to do that? I am using OC though. Thanks :)

Use the OC Configuration and in the device properties you will have an option to add devices, just click and select pci bridge and it will automatically add, can be 4-5 pci bridges, select the correct ones according to your ioreg.

I am working on the RX 480, so far the SSDT method doesn’t work.
Only injecting through device properties work.

My Nitro RX 480 have 1276 Mhz Gpu clock and 2000 Mhz for the memories.

With WEG I get like 117000 Open Cl score and with the modifications I get 137600. People with RX 580 that has 1366/1400 Mhz Gpu Clock should get more speed.

Weird thing is that after a sleeping cycle I get more performance..,
I have other problem with my RX580 . before sleep GPU memory are loading slowly to full 96% take about 12-20hour. after sleep GPU memory are empty till 5-10% ( that should be normal ) and again grow slowly.
I use only WEG/Lilu without any add device. smbios 19.1 z390 / 9900k

Saw that too, especially using Safari Browser.

Edit : The internet is full of problems like that with the AMD memory full in macOS.

Wow 117000 OpenCL is huge number for an non-modded RX480 !
I only get 26539 OpenCL on RX580 Nitro+ on Catalina. But get ~60% more on Mojave.

Awaiting to find out what modifications are ;)

My question may sound dumb to you, but I am really new to customizing this part. The Hackintool even identified my 9900k as 8th Gen and I have no idea where and how could I correct it. For your suggestion, what model name should I replace that '???'? Thanks for your patience :)

Geekbench 4 = 117,000, Geekbench 5 = 30,000. It must have been a GB4 bench at 117,000.GB 4 RX 480.png

Phew ! Thx for the clarification.
Ok I get it now. Would it not be great if everyone just used ONE benchmark ;)

With GB4, I get 115,879 on 10.15.4
But GB5 it's very low on 10.15.4 compared to GB5 on 10.14.6 (40% lower).

I just stumbled upon this thread and read it in its entirety to see if it will improve performance with my RX580 / HackPro5,1. I already tried R***B*** without any improvement. Is "The SSDT" for the RX580 expected to yield performance improvements if R****B**** did not?

My system is as follows:
  • Socket 1156 / H55 / Xeon X3460 / 16GB DDR3-1600
  • SMBIOS MacModel: MacPro5,1
  • Sapphire Pulse RX580 4GB
  • Clover (Legacy) r5115 (boot-arg: -no_compat_check)
  • Catalina 10.15.4
  • Lilu 1.4.3, WEG 1.3.8
