are you saying that i can run under linux, before loading ccminer, a nvidia-smi sentence that will change in real time the TDP of every card??? WOW!!! I thought that the only way was modifying the BIOS!, do you have any link / tuto or hint how to?, I will get right on it!.

I just tried in windows and it works. I'm pretty sure it should work also in linux but cannot test it because I don't have a ready linux install anymore. Setting the core and mem clocks(+changing to p0) works exactly the same way on linux and windows. Tested on 960, 970 and 980.

Those are the commands:
nvidia-smi -q -d POWER -i 0 -shows the actual setting and possible settings limits

nvidia-smi -pl 180 -i 0 -sets the power limit of gpu 0 to 180W

The successfull result:

Wow thx
Did anyone try this on a 980ti ?

Ps Cryptsy is off the market now.

almost finished my mates machine - having issues with the last card and the nvidia drivers accepting it - but can test this on his system the way it is while i still have it ...

will do that later this afternoon / tonight if i can get the chance - unless someone beats me to it ... which is more likely the case ...
