AMD Radeon Performance Enhanced SSDT

[ksy]

If you have an Ivy Bridge CPU (I think you do) you can follow this guide to create an SSDT for proper power management:
CPU SSDT script guide
I have another machine with an i7 3770 and without creating an SSDT, performance was terrible.
After you try that, post to the correct section if you have any more CPU issues.

If you want to understand this stuff, use this guide https://dortania.github.io/Getting-Started-With-ACPI/

Ok

OK, i tried doing the geekbench test and it gave me: 81229. Thanks for all @mattystonnie !

Edit.I also tried premiere pro with metal rendering, but it always jerky. Is it a premiere problem?

I meant 10.15.5 obviously. Sorry for the typo.

Not sure anyone has tried. I know the method using the radeon boost.kext does not. That method causes a KP in 10.15.5.

We will see what is to be done with the release of 10.15.5 .

Do you have an option there to select metal or open cl?

Yes, but if I put "opencl" it's ok, if I put "metal" the rendering is really slow

This is why I am asking. As far as I can tell both methods accomplish the same thing: Let macOS load the SMU firmware to the GPU. The kernel panic seems to only happen when used with the Radeon framebuffer but not with names ones.

That's for Clover.

You might have to change the PciRoot path (check yours with Hackintool >> PCIe >> Device Path)

Shouldn't this be:

Early SSDT for the rx 580, works best with Catalina, for Mojave I don't know.

My Sapphire Nitro RX 480 8GB has a clock of 1276 Mhz, so RX 580 should get a higher score.

How to install : use the SSDT into Clover/acpi/patched + WEG.

Also test after a sleep/ wake cycle, for me worked without.

For the second stage boot loading bar use the first display port of your GPU.

More good things are coming, trying to inject properties from the Radeon Pro 580.

For some reason I can't open this in MaciASL. Can you please post the text inside?
