Hi,
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): Option "Coolbits" "8"
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.
