[GUIDE] Injection of AMD Vega Power and Fan Control Properties

[jaymonkey]

In Hackintool it seems to be labelled correctly as GFX0, but when I try to run "./gfxutil -f GFX0" I get "error: unsupported registry entry class type 'IORegistryEntry'."

@bendelaurence,

If Hackintool is reporting the device as GFX0 then you should be fine, the version of gfxutil attached to the guide is old and can be a bit finicky on some systems, @headkaze gave it a big overhaul some time ago .. try this version

No need to pass it any parameters, it should find all devices and list the names and pci paths.

I also seem to be suffering from this 'Mojave can't preview jpg problem' which is apparently solved by whatevergreen

That sounds like you don't have IQS working (Intel Quick Sync).
IGPU should be enabled in the BIOS and the Vega 64 configured as the Primary, then configure the IGPU as "Headless"

Thanks Jay, plenty of great information there to get me moving forward. The only thing I may be missing is where to place:

<key>PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)</key>
<dict>

</dict>

...in my config.plist given the absence of:

<key>Properties</key>

There is a lot of card specific info in @CMMChris 's posts. Very close to getting this boxed off

Good evening to all,
Probably the question I will ask you, has already been asked by some other user...,
but I have tried to read various posts and I haven't been able to find the answer yet,
so..., I ask you in advance to apologize if that was the case.
Can I use this utility/injection with an RX580?

@lucke77,

The VGTab Utility only supports generating a SoftPowerPlayTable (SPPT) for the AMD Vega range of GPU's.
@CMMChris's Excel spreadsheet method supports Vega, Radeon VII and 5700 GPU's via separate (spreadsheet's)
As far as I know there are no utilities to generate a SPPT for RX 580.

Cheers

Polaris cards don't support PowerPlay Tables. I tried it together with others who use a Polaris card. There is a PowerPlay Table inside the VBIOS but injecting a customized table does nothing. So the only way to customize Polaris cards on macOS is by editing their VBIOS. There are plenty of tools for that. You will need Windows tho and of course there is a risk bricking the card.

Do I need this fix for Catalina? I can't tell if my fans are goinggrazy but seem strange that when I hand touch my Vega 64 is always very warm. even an idle. Cheers

It's normal for the backplate to get hot.

Please can you explain, I'm interested to get GPU temp on Radeon VII.

@iLikeHackintosh,

The tool i was referring is for setting SoftPowerPlayTable values, it will not help in reading GPU temp.
See this post for more info :-

[TOOL] Radeon VII PowerPlay Table Generator (OC, UV, Fan Curve)

Removed. Since I was getting banned from here for helping others I am not interested in supporting this platform with my content any longer. Bye.

Any ide how to get temp readings on Radeon VII on Catalina by using VirtualSMC.kext?
