Hi,

I found out that the nvidia macos webdrivers contain parameter/argument strings just like the linux version:

/Library/Extensions/NVDAGP100HalWeb.kext/Contents/MacOS/NVDAGP100HalWeb:

_clkSetSppllForDpOverclock_STUB
_thermDisableIdleSlowdownWAR_STUB

And in /Library/Extensions/NVDAResmanWeb.kext/Contents/MacOS/NVDAResmanWeb:

PerfLevelSrc
PowerMizerEnable
PowerMizerDefaultAC
PowerMizerLevel
PowerMizerHardLevel
PowerMizerHardLevelAC
AllowMaxPerf
DisableOverclockedPstates
RMEnableOverclockingAllPstates
_clkSetSppllForDpOverclock_STUB
_clkForceClockSlowdown_STUB
_gcxDeepIdleOverrideStopClocks_STUB
_mcConfigureIdleClockSlowdownCounter_STUB
_thermConfigureIdleClockSlowdownForMc_STUB
RMForceLockedClocksMode
_thermDisableIdleSlowdownWAR_STUB
RmOverrideIdleSlowdownSettings

 

Regarding the following links, it may be possible to enable specific power profiles under macos, too:

seems to be possible in linux to add switches to the nvidia driver:

http://us.download.nvidia.com/XFree86/Linux-x86_64/364.19/README/xconfigoptions.html (Coolbits needs to be 12 as it seems)

 

PowerMizerEnable=0x1; PowerMizerDefaultAC=0x3;

How could you pass these arguments to the NVDAResmanWeb.kext?  My problem basically is, that the idle frequency of my 1050 Ti seems to be pretty low, resulting in laggy windows e.g. on resizing.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

This looks interesting, would be nice to control the fan curve on the GPU and/or OC the card a bit 😃
