I would like to increase Power Target for my card (GTX 680). Currently it underclocks so bad sometimes that I even do not get stock boost frequency (it is Gigabyte OC card). At the moment I think I’m on default 100% Power Target. Stock BIOS allows me to increase it up to 111% (260W). But how do I increase it in Linux? I googled, but all I have found is -pl argument for nvidia-smi, but if I try to run “nvidia-smi -pl 260”, I get this error:
Changing power management limit is not supported for GPU: 0000:01:00.0. Treating as warning and moving on. All done.
Please note that at the moment I’m looking for a safe way to do this (no flashing, no hardware mods). Or setting Power Target is not supported yet?
