Unable to unlock overclocking options for a Quadro P2000 Mobile


I am trying to overclock my Quadro P2000 mobile, mostly out of curiosity. I am running a Lenovo P52, openSUSE Linux, Nvidia Drivers 430.26. I have enabled the Coolbits option in xorg.conf, as confirmed by the following ouptut in the system journal:

Jul 02 16:46:42 rombert /usr/lib/gdm/gdm-x-session[17828]: (II) NVIDIA(0): Creating default Display subsection in Screen section

Jul 02 16:46:42 rombert /usr/lib/gdm/gdm-x-session[17828]: (**) NVIDIA(0): Enabling 2D acceleration

However, the overclocking option does not appear in nvidia-settings. As expected, the CLI does not work either

$ nvidia-settings -a [gpu:0]/GPUGraphicsClockOffset[3]=50

ERROR: The attribute 'GPUGraphicsClockOffset' specified in assignment '[gpu:0]/GPUGraphicsClockOffset[3]=50' cannot be assigned (it is a read-only attribute).```

System information:

To my understanding this should work, and it is working on my desktop. Does anyone know whether this is a limitation of the specific card/laptop? Or maybe not supported by the drivers at all?

Any help would be appreciated.

That feature is basically one for consumer geforce type products. Rarely works/is enabled on mobile chips due to power restrictions. Also I don’t know if this is working on Quadro type cards at all since those have the luxury feature to set clocks through nvidia-smi without fiddling with the xserver.

Thanks generix. I am unable to set clocks higher using nvidia-smi as the highest values correspond to performance level 3.

Guess there is now way to overclock a Quadro P2000 Mobile.
