Hello mattystonnie,

I tried SSDT-RX580, but it seems no effect. I have attached the IORegistry, EFI folder. I checked System Preference => PCI, however there was nothing thus I think I am not doing this correctly.
I appreciate your help.
Thank you.

That's correct. Even if you did makes the changes correctly, there's no more performance that can be gained from RX580.

EDIT. That SSDT version 1.0 has not worked and will not work you as it assumes you have External (DTGP, MethodObj) somewhere in your DSDT and you do not have that.

Instead, you can try the one I modified and posted here. That will make the changes but as I said above, you will not see any significant benefit in performance on an RX580.

Replace, enable IGPU in Bios DVMT Pre-allocated 64 or 128 mb, DGPU as primary.

Send me Ioreg after ;).

Hello there,

Replace and check again, I changed your SMBios to iMac Pro 1,1 for better CPU power management, mine is the same.

Hey man,

Please upload your EFI folder, power management is wrong and the SSDT is not applied correctly

Hi,

Here is the IORegistry after the modification. DVMT Pre-allocated is set to 128mb.

Thank you.
