AMD Radeon Performance Enhanced SSDT

[1900]

Those are PCI Bridges,you can add a name for them using clover device properties.

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

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..,

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 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.

What SMBIOS model-ID are you using ?

iMac 19,2

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).
