dauerhafte einstellungen für eigene clock settings:

The overclock settings are not wrtten to the ~/.nvidia-settings-rc
file by default and therefore the settings will not survive restarting
X.
To fix this, quit nvidia-settings if it is running, open
~/.nvidia-settings-rc in a text editor and add the following lines:

GPUOverclockingState=1
GPU2DClockFreqs=625,805
GPU3DClockFreqs=625,805

Save this under a different filename; such as
.my-nv-settings-rc, start nvidia-settings; specifying the custom
configuration file:

nvidia-settings --config=~/.my-nv-settings-rc

This line can be added to ~/.xinitrc file to start nvidia-settings with the specified clock frequencies when logging into X.

These and all other possible attribute settings and their current values can be listed with the following command:

nvidia-settings -q all
