The gpu cloc lock? Remember, its for octopus (conflux/CFX)
First bump up your power limit, for example 170. Don’t worry, the real power usage will drop after the next step.
Then use smi command in Hive Shell:
nvidia-smi -lgc 1550
1550
can be changed to your desired core clock, but I find 1550 pretty good). The power will drop to whatever the card needs, and stay below your power limit (as you can see in my screenshot)
Remember that this will change core clock of all the GPU’s in this rig.
Hope this helps
