pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD 6600 XT

[Huitzilopochtli]

I was lucky to get hold of a Radeon VII, because I only use Davinci Resolve where I need graphical power. So I was wondering if the Radeon.boost is still working/needed in Big Sur and if it is still possible to use Powertables. I read in a German Hackintosh forum that Big Sur doesn't allow any Device property changes any more. Is that correct, or what is your experience?

Edit: I just read the last post about the radeonboost.kext ... But what about the PPt's? What would be the best values for an Radeon VII to run smoothly?

I haven't done any testing (been a little busy recently) but Azimuth1 says PPT is not working.

Hi @pastrychef,
Just curious - are you planning to update the main thread regarding to Big Sur ?
Thanks!

I just talked to CMMChris, and he says that PPts still work in Big Sur. I will do some testing.

ok .. too bad... but even if I inject the devices properties among the PCI tree?

May I ask what all these values mean? With my Vega 56 I only used the PP_PhmSoftPowerPlayTable values... Besides, CMMCHris reccomends to use PP_DisableDIDT=1 (Number) and PP,PP_DisableULV=0 (Number) for the Radeon Vega VII

I don't know. I never looked in to what each of the individual settings do.

I wasn't planning on any updates. The installation procedure is pretty much the same as it has always been and I update the EFI folders on a pretty regular basis. It's just a matter of using the latest EFI to get Big Sur working.

You will have better luck with my Z390 EFI (link to my Z390 build is below, in my signature).

1. In config.plist > DeviceProperties, delete everything except the audio device.
2. In config.plist > Kernel > Add, disable my USB ports kext.
3. In config.plist > Kernel > Quirks, enable XhciPortLimit.
4. In config.plist > NVRAM > 7C436110-AB2A-4BBB-A880-FE41995C9F82 > boot-args, add "agdpmod=pikera" (without the quotes).

After you have macOS installed and running, create your own USB ports kext. Add it to the EFI and enable it in config.plist and disable XhciPortLimit.

I also highly advise that you read through posts #1 and 3 in my Z390 thread.

I took into account all the changes, but got this message, this is very new to me, I ask for advice.
After this message, the boot source selection menu appears and I see all the options and my drive, but I cannot select because there is no response to keyboard presses.

Can you suggest the reason for this oc response?
