Hi Toleda, Ive just got my RX580 plugged into My iMac pro 1,1 style Skylake build based on kgps setup. The card is working fine with the new Whatevergreen + Lilu kext. I am transitioning from Nvidia SSDT to the one for the RX 580, but I am really not sure how to generate the right values for the card or what are the right parameters to add to make my Old SSDT compatible. Ive removed the Nvidia Arguments.

Thank you

No ssdt required for RX 580, remove.

Yes

Thank you, sir, after this, Geekbench openCL test result still shows that my RX 560 max clock speed is only 300Mhz.

Hello! Would you be able to double check my file? It looks like power management does not seem to be fully working (Idles at 45-52) but in windows, it idles at 27-30. I have native PM working for the CPU (downclocks to 800 mhz on idle)

Im also missing: Heuristic-ID: 4

Ive attached ioreg, config.plist, kexts, etc. Thank you!!

Hardware:
SMBIOS= imac 17,1
Gigabyte Z170XP SLI
i5 6600k
Sapphire Nitro+ RX 580 8GB
Running Mojave 10.14.1

What are you using to compare?
Oranges and Apples

Im also missing: Heuristic-ID: 4

Why?
RX 580 PM configured correctly

Thought it had to be 4 but it looks like it's different and ok as long as they match. Thanks.

As for temp, i used HW monitor/terminal for mac and gpu-z for windows. The card runs(and feels) hotter in macOS and fans spin up at 52, cool down to 45 and stop spinning. Warms back up to 52. Starts spinning, Repeats every few minutes

ioreg -l |grep \"PerformanceStatistics\" | cut -d '{' -f 2 | tr '|' ',' | tr -d '}' | tr ',' '\n'|grep 'Temp\|Fan'
"Fan Speed(%)"=0
"Fan Speed(RPM)"=0
"Temperature(C)"=52
