Macbook Pro: can't overclock Nvidia 320M (MPC89) with nvidia-settings

I would like to overclock the graphics on my Macbook Pro 7,1 with Nvidia 320M (MPC89) integrated graphics, using the nvidia-beta 270.30-2 proprietary driver. I know the risks involved. However the usual nvidia commands do not seem to work:

If I set it like this:

$ nvidia-settings --assign "[gpu:0]/GPUOverclockingState=1" --assign="[gpu:0]/GPU3DClockFreqs=550,1200"

  Attribute 'GPUOverclockingState' (arch-macbookpro:0[gpu:0]) assigned value 1.

  Attribute 'GPU3DClockFreqs' (arch-macbookpro:0[gpu:0]) assigned value 550,1200.

When I then check the settings I see default values again, and not the ones I set:

$ nvidia-settings -q all  | grep GPU3D

  Attribute 'GPU3DClockFreqs' (arch-macbookpro:0.0): 450,1064.
    The valid values for 'GPU3DClockFreqs' are in the ranges 112 - 900, 266 - 1276 (inclusive).
    'GPU3DClockFreqs' can use the following target types: X Screen, GPU.
  Attribute 'GPU3DClockFreqs' (arch-macbookpro:0[gpu:0]): 450,1064.
    The valid values for 'GPU3DClockFreqs' are in the ranges 112 - 900, 266 - 1276 (inclusive).
    'GPU3DClockFreqs' can use the following target types: X Screen, GPU.

Are there any other ways to try?

Did you activate coolbits in xorg.conf (or 20-nvidia.conf)? Even so, from what I know, overclocking isn't supported on mobile cards.

I have ' Option "Coolbits" "1" ' in my own file, /etc/X11/xorg.conf.d/50-nvidia.conf .
