Hey, I've been reading this thread for a while and tried all of the versions of SSDT for my Vega 64 (its an MSI Airboost Varient) The SSDTS are definitely being applied, but I can't get my geek bench scores to break 52000ish. Any help would be greatly appreciated.

EDIT - IOREG AND EFI ATTACHED

I have applied the SSDT for my Vega 56, it works fine with VegaTab_56.kext. However, I also noticed the device names that show in Hackintool are not correct.

Please see the screensnap, there are two devices show as '???', which I believe they belong to my Vega56.
Screen Shot 2020-04-29 at 4.57.07 PM.png

The device paths are:
PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)
PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)

And the IOReg IONames are:
IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/PEG0@1/IOPP/PEGP@0
IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/PEG0@1/IOPP/PEGP@0/IOPP/VEGA@0

I didn't apply any name changing patches.

Not I. jus using WEG + Orinoco FB


Running on 10.14.6
That's interesting.

On my system (i7-3770K + RX580 as iMacPro1,1 booting either 10.14.6 or 10.15.4),
I get the following Geekbench 5 scores:

10.14.6: 42891 (OpenCL), 41631 (Metal)

BUT, with

10.15.4: 26539 (OpenCL), 26738 (Metal) => almost 40% LESS on Catalina !!!

Something is wrong with 10.15.4 on my system o_O

Same system, different results on different OS's.

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..,
