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:
Microsoft Windows [Version 6.1.7601]
