Hi All, I have a couple of questions if anyone can help

Can anyone tell me what the P Values in Overdriventool change. I believe P7 is the memory frequecy of the card and P3 the cards Ram? but what are the others.

also, I always stop the miner before making any changes in Overdriventool. Is it ok to make changes while the miner is running?

Thanks

Explanation from a ignorant non-expert

There are P1-P7 for the core which includes frequency and voltage and the is P1-P3 for the Memory which includes frequency and voltage. Think of them as GPU presets. They GPU selects a preset based on load. Here is an example for what I am trying to say. These percentages are completely made up but the principle is what I am trying to convey.

    % Load     P-State
    <5.          P0
    <10.        P1
    10-20.      P2
    21-30.      P3
    31-50.      P4
    51-70.      P5
    71-95.      P6
    96-100.    P7


Same for memory P states except there are 5 states
