Undervolting is not harmful to the cards. Basically if the voltage is too low for what the card is doing it will either disregard the setting or crash. Neither causes damage to the hardware. Lowering the power limit too much will lower hash rate though.

Hi, short answer, you cant with any degree of accuracy.
The power used is proportional to the voltage and the clock frequency.

Thanks for the answer , it's similliar to what I've thought. That being said do you think that this might be harmful to cards ? Though I dont see anything wrong with setting constant voltage as this is just as limiting power limit , since card cannot pass the voltagepoint you can set ,e.g. it cannot draw more power than what you give it.

Hey there guys I have pretty straight forward question to the ones that are using Nvidia inspector . How do you determine (if you use -lockVoltagepoint argument) at what constant voltage to run the card. I've found that locking certain voltage , overdrives power limit since if you lock voltage at 950 mv and card is even at 110 % Power limit , it will never push to there , since the max voltage the core can use is 950 mv. That being said do you know how to determine what voltage corresponds to what power limit ? Like 65 % power limit = 880 mv voltage for example ? (<-- i dont know if this is right) . I know perfectly fine that different cards like 1060 / 1070 / 1080 ti have absolutely different voltages and since that 65 power limit at 880 mv can be hole different for other cards !
