Is there a way to undervolt nvidia gpu in FreeBSD ? i have 250W gpu but i want to make it 200W.
Cant find anything regarding pc gpu , only laptops with optimus.
 
Just of curiosity (I cannot give you any usable answer, sorry):
I've heard a lot of overvoltage a CPU, but why do you want to undervoltage a GPU?

Two reasons:
1: I have petg hard tubing, so want to keep temps lower to keep them longer.
2: 250W vs 200W on llm`s is such a small difference and want my pc to use as low as possible watts without hurting to much. Ive already reduced cpu power.
 
I do not have nvidia device on Fbsd. But on the other platform (xbmc/nas/nzb/steam/etc box) I do something like this to establish a power envelope (do not use these values , adjust accordingly)

Code: 
#nvidia-smi --reset-memory-clocks
#nvidia-smi --reset-gpu-clocks
#nvidia-smi -i 0 --query-supported-clocks=mem,gr

#nvidia-smi -pm 1
#nvidia-smi -pl 120 -i 0
#nvidia-smi --lock-memory-clocks=405,5001
#nvidia-smi --lock-gpu-clocks=405,1890

Never knew nvidia-smi is a tool to do stuff like this.
