    What speed do you hit if you just raise the temp and power limits to max? Also have you unlocked the voltage control?

    It's not your card that doesn't like overclocking, that curve is just not going to be stable for majority of cards.

    Do this.

    Reset to default, bring up the curve

    Hold shift and drag the whole curve down so that the points on the right are at max frequency of about 1900mhz.

    Next, select a single point and drag it up to perhaps 2000mhz.
    I would start off with a voltage of 1.025.

    So 1.025v @ 2000mhz~.

    All the points past 1.025v will be the same(this ensures it does not go past the first set point).

    After that, the 3 or 4 points below 1.025, you'll want to reduce them by 13mhz step each.
    so it would be 2000 @ 1.025, 1987 @ 1.012, 1970 @ 1.0v and so on.

    You do not want to go beyond 1.06v~ for most cases as the average frequency will go down due to limited power target.

    Reducing voltages reduces power usage which will lower temps while keeping average clock speeds up.

    If above is not stable, maybe try 2ghz at 1.0375v or 1987@ 1.025v etc.

    Thanks I'll try it out later. :D

    I've tried as you suggested but for some reason my card is running at 1974mhz @1.025v when running the heaven benchmark. o_O

    Trying your second suggestion gives me this:

    Card seems stuck at 1974 no matter what but at least the traditional method gives me 2ghz for a while before going down to 1974. This just shot to that right away. I did set the power limit to still be at 135% because I know that I need that to be stable at 2ghz otherwise it's an instant crash.
    I do really appreciate the help but it seems this card really doesn't respond well to voltage curve overclocking.

    It's normal behavior.

    Pascal has one boost bin drop at 35c, then another bin drop somewhere around 50-60~ degrees, hence 1974.

    To counteract that, you would want to set 2025(provided you are stable at 2025) because once temperatures stabilize, it will drop clock by a bin or two.

    Hmm so you would suggest trying 2025mhz at 1.0375v? By the way, is there a way to create custom voltage points? I actually don't have 1.0375 but 1.031 and 1.043.

    In a nutshell, Pascal can be very frustrating to OC, certainly for those with great cooling solutions as its power draw that is now the limiting factor rather than temps :(

    Yeah I just failed again. Honestly right now even the slightest deviation from my current curve will cause it to crash no matter what. I think if I did overclock via the curve method, it would turn out exactly the same as what I am getting the traditional way. In other words; not worth the trouble. Thanks for the help anyways guys.

    Its all a bit odd, ive never seen anything on a Ti not being able to hit 2ghz off the bat without anything other than raising the power and temp limits and adding a little bit to the core clock.

    Mine was just as bad.
    I fitted an Accelero III cooler to it and can just scrape past 2GHz now.
    No chance before.

    Im at 2050mhz with just the power and tempo limits raised to max, nothing on the core and nicely stable with very rare drops due to the power limit being hit (but only in certain games (not necessarily new ones either)). Ive had it stable at 2075 via adjusting the curve but since adding a new SSD and a W10 64 clean install ive just gone with the normal method with AB.
    Came back from holiday and although the house heating was on, i keep it cool in the mancave, Five mins after booting up my water temp was 11C and GPU at 12C Bbbrrrrrrrr

    I'm not sure of the point you are making...

    Seriously?
    I thought you quoted me because you had something to contribute to a discussion.
    I ask what it is ...

    A discussion on a 1080Ti thread and im talking about a Ti, fancy that. The quote was obviously an anomaly .

    Thanks guys I had a pretty good laugh. Let's not let this get ugly though.
    Yeah it is frustrating. I kinda almost expected an easy 2ghz. Especially since I bought a card with some of the best air cooling available. But it is what it is. The difference in fps at 4k between 1974mhz and 2ghz isn't even 1fps I believe so I don't think it's that big of a deal. We really need a pascal bios mod.

    I seem to have a fan curve that is working a little better. Still testing it but it's keeping me at 1987mhz. Instead of resetting everything and adjusting the curve, I took my current OC curve and adjusted that.
    Edit: Nope...still drops to 1974 on superposition. I guess heat is the limiting factor. If I had it on water I could keep a good 2ghz or so but I don't think it's worth it. Honestly I have no problem with my card hitting 70c. I really dislike this new boost 3.0.

    What happens in games, does it drop the same? One of the Kombuster tests makes mine drop to well under 2000mhz.

    My 980-ti just died in flame, literally.... I might jump on 1080-ti but those prices holy crap

    1080ti is an awesome upgrade from a 980ti but the prices are mad
