<< Solved >> AMD WX4170 dGPU on ZBook G5 17 Laptop

For PM you should see something along the lines of:

Mine not PR, as they are CPU

Done some battery only tests so list of FB, which can work without power cord on low frequency (Core 214 mhz, 15W):
Salado (non listed in info.plist, but in 9500 controller)
Exmore not stable, long switch to power save mode, gpu eats all power, than freeze, than low power mode enabled (non listed in info.plist, but in 9500 controller)

Anyway, non one of them return high profile powerstate after power connector was connected

Yes that may be part of the driver itself, real macs get hot very easily, so I guess if you don't put a load on the GPU, the driver want's to keep the clock down.

Using my "Acre" Powerplay table the 4170 idles @ 17W, but can go up to 125W on load.
Still gives only about 95% of what Windows drivers get me performance wise, but it's fine for my use.
Just need Catalina to load!

Have you tested Catalina or Big Sur?

That looks correct now, the IOreg version you uploaded before didn't have the X86PlatformPlugin enabled.

Nope, i am on High Sierra, was planning to change GTX1060 to RX580 for eGPU but stuck on problem, when external gpu send video signal back to internal gpu via pci. And at that point i have Kernel panic, or artifacts (

On Battery only I get terrible throttling in Mac (Both CPU and GPU) but there's almost no information on how to change that.
Also Thermally the ZBook can handle a lot more than what OSX limits.
I guess it's one of the downsides.
Still performance is pretty much on par with a Real MacBookPro 15,1 and the ZBook is dead silent and has a nice 17" screen.

I get terrible throttling in Mac

Its not trotling, its power saving. Windows have option "High perfomance profile" and running cpu on 3.2 ghz, while macos have same power saving mode as in windows and mine cpu will run on 2.7 Ghz. mine zbook g3 eats about 170wats on full load on a\c

ps, its Intel

Palena is really the best with hotplug action

But not so fast and stable as Salado. If i unplug power the laptop just freezing as gpu have not enough power to work
Even colors on internal screen became more realistic!

Thanks!


I will leave it here. Maybe it will be useful!

And the lag on close lid disapears!

The next step is to implement this flags to salado or baladi, bernice to compare power saving mode
And find out how to adjust brightness of led display

Trust me, try the kext I attached above that injects Acre's PowerPlay tables, and then just patch your connectors like I posted before, using the default framebuffer.
It beats Palena by more than 15fps on cinebench and clocks down just the same. And after 2 days of heavy testing trying to crash it, It's solid.

okay, i will try!
how did you patch connectors? (i mean where? clover kext patch, dsdt?)




I done 1 more test of Baladi
And Baladi is most low power usage, working from battery, but will not work high power profile until restart if the A\C was removed. 10-12W

And Baladi appears as default framebuffer

Baladi, default framebuffer mouse lag when lcd lid is closed, or opened after close state. This glitch is affecting only on lcd

Directly in config.plist->Devices
