Q. I use the Coolbits overclocking interface to adjust my graphics card's
clock frequencies, but the defaults are reset whenever X is restarted. How
do I make my changes persistent?
A. Clock frequency settings are not saved/restored automatically by default to
avoid potential stability and other problems that may be encountered if the
chosen frequency settings differ from the defaults qualified by the
manufacturer. You can use the command line below in '~/.xinitrc' to
automatically apply custom clock frequency settings when the X server is
# nvidia-settings -a GPUOverclockingState=1 -a
GPU2DClockFreqs=<GPU>,<MEM> -a GPU3DClockFreqs=<GPU>,<MEM>
Here '<GPU>' and '<MEM>' are the desired GPU and video memory frequencies
(in MHz), respectively.
