Nvidia GPU power consumption control

[LevelGD]

Is there an easy way to add GUI option to limit power draw? 

I found that through console you can limit power usage (120w is lowest setting for me). Or console is only way?

I don't think the NVidia Linux driver let's you to touch the power draw options at all, at least not directly.

 

FWIW you could take a look at "Coolbits" option in xorg.conf. See: http://us.download.nvidia.com/XFree86/Linux-x86_64/430.50/README/xconfigoptions.html

 

After you have enabled bit 3, you should be able to apply setting "per-clock domain and per-performance level offsets to apply to clock values". However, that does not apply to power level per se, but underclocking will reduce power draw, and might work for you, depending on your actual goal.

 

Last time I checked there was little working over- (or under-) clocking utilities on Linux for NVidia (and this kind of tinkering falls in that category). But I've since moved away from team green to red so can not try it out for myself anymore.

 

EDIT: Bit 4 also allows overvoltage via CLI, according to the same documentation I linked. It might also allow undervolting, although it is not mentioned in the documentation. Also, no GUI...

sudo nvidia-smi -pm 1
sudo nvidia-smi -pl 125

It seems -pl too low or high there's response "i only can do xxx-xxx values" that's awesome.

Kinda worked for me. After some Skyrim my PC exhaust side was not as hot as usual. At least I do believe it.
