    Use MSI Afterburners graph tool to see if it is the gfx card that is limiting you or something outside that.

    Did you try using a voltage curve yet in MSI Afterburner so you do not hit limits while having a maxed out overclock.Lots of ways to do it in this thread.

    EG:
    Set MSI Afterburner to default.
    Press control + F to get voltage curve.
    Move only single point on voltage curve.
    Lets say 1.02mV for now(you can lower later if you want for now voltage is for stability)
    Move voltage point 1.02mV up to 2038 Mhz.
    Hit red X or close voltage curve.Then click on check mark in MSI Afterburner to apply voltage curve.
    This will result in a flat line voltage curve starting at 1.02 mV and 2038Mhz.
    Setting the voltage curve this way will result in your MHZ to drop by increments of 13Mhz until temperature of the card is under control .Say under 70C.
    Set a fan curve next to run at 70% fan speed at 60C GPU temperature .
    Result should be a drop of two bins (so 26Mhz in total )So the GPU clock will settle at 2012 when card get to a normal running temperature (again say under 70C)

    See screen shot for a general idea how to set.

    First of all, thanks to everybody for the answers. Now, I'll try to answer:

    @tensai28 That's also what I thought but I did not try yet, gonna do it soon.

    @Mufflore Exactly for which parameter should I enable the monitoring? The power limit percentage is on already and as I said it rarely goes past 120%.

    @gerardfraser I am using the frequency/voltage curve to tweak the GPU already (which is actually the best tool to overclock more effectively). Basically what I did for now was to set 1.081/2050MHz. Then I saved and I did not touch anything else. The Strix OC even allows me to keep the temps under 62 degrees C, which in my case is the point where frequencies start to be cut. Are you suggesting me to try a lower frequency with a lower voltage as a starting point and try to go up till the card starts to limit the core clock again? Based on my experience, the only frequency which stays locked in every scenario is 2025 MHz. I wanted to go a bit further just for fun though and see if I could get some more of that green juice. :D

    EDIT: the card behaves exactly as you described in your short guide. I ran Superposition again (4k Opt) @ 2038MHz/1.025V. Soon after I started the bench core went to 2025, after a while it went down further sitting steadily at 2012MHz. So, now should I try to give a bit more voltage to see if it keeps the desired OC?

    Well I can suggest keep voltage @ 1.02 and bump up to 2070 and see if you can hold 2050 at that voltage,no need for highest voltage on GTX 1080Ti when the card can run at lower voltage with same clocks.It is just a matter of experimenting to see what your card will run at.Lots of people run with 0.993/1.000 voltage also for same clocks.

    If you look at my screenshot run 1.00mv with 99% GPU usage for hours,now I can run higher on OC but there is really no real gaming difference other than couple FPS when gaming even @2100Mhz

    Great, I understood a bit better how the OC works with Pascal, basically what matters is not getting a steady frequency, but rather limiting the range within the card downclocks, i.e. getting 13-26MHz less than the set core frequency instead of 80-100 MHz (and that would be indeed noticeable framerate wise). In the end it is better to choose a lower but steadier clock than an higher one which would maybe be stable for a while but then it would get cut heavily due to temps or current limits.

    All the limits, gpu use, core clock, fps, GPU temp, power %, CPU use per core and anything else you want to observe.

    I finally found the sweet spot thanks to the voltage curve: 1.043V max, 2050MHz, fans @80%. With these settings I never go under 2025MHz, I'm pretty satisfied I must say. Thx again everybody! :)

    Anybody noticed any price drops? In Sweden the price of my card has lowered slightly but is still more expensive today than when I bought it back when it was released.

    Because I watercooled mine I bought the Founder's Edition back then, for €782 without shipping. The FE isn't available anymore, but right now there are 23 different 1080TIs available at the same retailer (mindfactory.de) that are cheaper, and most of them are in stock and can be shipped within the weekday or two at most I'd say.

    Good job ,nice overclock and nice to read you found your sweet spot.

    Yep bought mines at "Webhallen" Gaming store for about 7,895 Swedish crowns, 880 US, August 2017.
    Now the last time checked the lowest net price is about 9,100 Swedish crowns, 1013 US. But that's at another store.

    This card I mean - ASUS ROG STRIX GeForce GTX 1080 Ti 11GB OC

    I need to upgrade like really soon, as a matter of fact I need a whole new system. Graphics wise still using a Gtx 980 for 1080p gaming but only 60hz considering the Rtx 2080ti will be out in a few days I may pick up a 1080ti used. Double the performance of a Gtx 980 with the 1080s (amazing)
