nvidia 260gtx: always high performance profile

Soukyuu · 2015-02-17 17:00:01

I have a nvidia 260gtx running the nvidia-340xx legacy drivers on KDE4. Looking at nvidia-settings, the powermizer entry shows "auto - adaptive", nvidia-settings reports 0% gpu usage, yet the clocks never leave the high performance level (2).
The power mode is set to adaptive if queried via console also:

$ nvidia-settings -q | grep PowerMizer
Attribute 'GPUPowerMizerMode' (Takemikazuchi:0[gpu:0]): 0.
    Valid values for 'GPUPowerMizerMode' are: 0, 1 and 2.
    'GPUPowerMizerMode' can use the following target types: GPU.
  Attribute 'GPUPowerMizerDefaultMode' (Takemikazuchi:0[gpu:0]): 0.
    'GPUPowerMizerDefaultMode' is an integer attribute.
    'GPUPowerMizerDefaultMode' is a read-only attribute.
    'GPUPowerMizerDefaultMode' can use the following target types: GPU.

I have tried disabling all effects in KWin, as well as switching to xrandr (which should use CPU instead). I have not used any xorg.conf files.

I have another PC with a 8600m GT (see sig), which switches to level 0 almost immediately. About the only difference I see is it running KDE5, and only having one monitor while my 260GTX one has two.
Any idea how to make it use levels 0-1?

Ok, this is weird. Apparently, the clocks are also stuck at their maximum on windows as well. Could it be some kind of BIOS modification MSI did in their version of the 260GTX card? It's the TwinFrozr version of it.

edit: double checked, nvidia control panel is set to "adaptive" on windows as well.
