@zakklol,
Nice find .....
I think the VGTab utility must enable PP_DisablePowerContainment so that people can create a SoftPowerPlayTable that overclocks the GPU and thus allows it to draw more power, seems pretty dumb that it disables this data point / sensor though as i would have thought anyone wanting to overclock a Vega would be interested in this value.
I tried setting it to 0 and can confirm that it does indeed re-enable the Total Power data point/sensor.
I'll add this finding to the guide, thanks for the feed back.
However i'm not so sure that the value is correct ...
On my system which has a Sapphire Vega 64 Liquid Cooled edition dGPU, at idle it hovers around 17 Watts, if i run a FurMark stress test in the default windowed mode the Total Power figure seems about right at 360 Watts.

But if i run a stress test at fullscreen (3440x1440) it shows around 680 Watts which is a crazy high TDP and can not be correct

Pretty sure that if it was really drawing that much power it would explode
That said I left it running the FurMark stress test at full screen for an hour and the cooling solution kept it at around 65 Degs C as per the Target Temp set with the VGTab utility.
It seems the larger the output window of a 3D app such as Furmark, Valley, Haven .. etc the higher the reading to the point where it can not possibly be correct ????
Pretty sure its a MacOS thing as if i execute the terminal command :-
It also reports incorrect Power readings when running a 3d app at fullscreen :-Code:ioreg -l |grep \"PerformanceStatistics\" | cut -d '{' -f 2 | tr '|' ',' | tr -d '}' | tr ',' '\n'|grep 'Temp\|Fan\|Power'
Would appreciate if you or anyone else could post what sort of power draw you see when the Vega is under load.Code:MonkeyMac-Pro-2018:~ Jay$ ioreg -l |grep \"PerformanceStatistics\" | cut -d '{' -f 2 | tr '|' ',' | tr -d '}' | tr ',' '\n'|grep 'Temp\|Fan\|Power' "Fan Speed(%)"=45 "Fan Speed(RPM)"=1501 "Temperature(C)"=33 "Total Power(W)"=683 MonkeyMac-Pro-2018:~ Jay$
If you don't have it already you can download FurMark for Mac OS here, once downloaded and unzipped run GpuTest_GUI.app.
Cheers
Jay
In regards to 10.14.5, I’m still having issues with fan speed etc. with my MSI Vega 56 Air Boost.
Had to reinstate my custom next. Maybe the overhauled drivers are specifically for OEM cards.
