This is strange... I was gaming and noticed that my core freq dropped for a second.  Looking at monitoring software, it appears the power limit hit 122% and the "Power limit" showed a value of '1' (IE: hit the built in power limit).  The thing that's strange is I've got it cranked up to 150% power limit, but it still maxed at 120?
 

 
It's the GTX 1080ti K|NGP|N Hydro Copper... as you can see temps are well in operating temperatures as well so no thermal throttling should have occurred. I'm running the Extreme Liquid cooling OC Bios on the LN2 switch as well.

    a 150% power limit is not happening on a stock 10 series card -- that would require harware modification - as far as I've seen

    there's no hardware modification outside of a BIOS that enables (or so it says) a 150% power limit.  Again, it's the K|NGP|N... so it's built for extreme OC without any hardware mods.

    That is going to happen from time to time. It's normal. Don't worry about it. One little spike isn't anything to worry about.

    Thanks, just caught me by surprise.  It was in Civ 6 of all things.

    I guess I'm still wondering why it hit power limit at 120% even though it's set to 150%?

    It's just a glitch that occurs.

    The above log is of me running through unigine superposition on its 8k preset. Notice the one perfcap that reads as "1" that is my card hitting the power limit at 124 when set to 150%.

    If your power limiting your need to reduce your over clock, i made a youtube video for this exact thing so people can watch how to overclock, heres the link - https://youtu.be/opq3dvXfJMU

    It's a feature. That's what you get for your $1000. 'It's just a glitch. Don't worry about it.' If it were me, I would be unsatisfied with the glitch or needing to lower my overclock in order to avoid hitting a limit which shouldn't be triggering.

    Nah, the op just needs to flash the xoc vbios to his card to disable power & temp limits.

    The xoc vbios I'm talking about isn't from asus.
