    Wasnt aimed specifically at you but rather in general, i have returned cards under warranty before no problem, even when the aircooler has been removed and replaced with a waterblock. Anyway for the last 10 years or so i replace my WCed card every other generation and put it in my lads WCed rig.

    Afterburner everytime and removing the stock cooler will possibly void the warranty but manufacturers and cards are all different on this. Generally replacing the standard paste with the right amount of decent TIM can cut temps by a significant amount, this is hugelly evident in gaming laptops where its not unusual to drop 10-15 C.

    Can't do that, it'd make too much noise. 70% fan is really loud already.
    Understood, I was used to older cards where I could give a +100Mhz in most cases without problems, that's why I'm surprised. Thanks!

    I meant set it to 100% while you Overclock to see if the card is throttling due to temps

    Hey guys,

    so i´ve been playing with my MSI 1080Ti Duke and i noticed that the fans only start working after the GPU reaches 60 degrees. Is this normal for this kind of GPU? It seems a little high for me and i remember that my previous 1070 would start the fans after reaching 50º and that was a much cooler chip.

    It started with Maxwell.

    This zotac 980ti Amp omega has it too, but I disabled it (bios flash) and set min fan 28% until 45C then it rises, 73C is 70% fan, etc.. mine spins up to max 2900rpm.

    I found it crap to be honest, now it idles at 28-30C and basically silent at 800rpm, before it idled ~45C.

    Its the same max wattage on all the cards :) you just have a lower idle wattage for energy saving (250 watts vs my 300) hence your higher percentage to get to the same max

    I am on the same boat with tensai28.
    No luck with the curve.
    I achieved +35 on the core and +350 on the memory with the traditional way.
    My card stays at 1949 while gaming though,
    cause my temps are in the low 80s(fan 100%).
    I noticed that tensai28 uses 135% power target, and as I am still learning the card I wonder if my 150% is the cause of the high temps.
    I thought that maximizing power target is a precondition for o/c the card.

    Not with pascal. You want to keep you power target as low as possible because the more energy you use, the hotter it gets and then it throttles. I've had better luck overclocking the memory. Try lowering to 125-135% and see if you're still stable.

    You want to keep the power USE as low as possible as once you hit 120% the card will throttle.
    These cards will throttle due to temps.
    AND
    Throttle if you hit 120% power.
    So you use the curve to hit a set core speed but at a lower voltage.

    So if my card throttles at 2100mhz at X volts (where X is a set voltage), then i use the curve to set X slightly lower. If i can run stable at 2100 with the voltage at the next increment down from X, chances are i wont hit the 120% cut off and the core wont throttle.

    The key to OCing these cards is keeping temps low and the stable voltage used as low as possible for the speed you want to run at.

    A fictitious example below.
    My card hits 120% power limit at 2100mhz stable at 1.3v but throttles.
    I set 2100mhz at 1.25v and it hits 115% and doesn't throttle and is still stable.

    Thanks for the info. I didn't know 120% made it throttle. I thought it was just based on temperature. Unfortunately I had to put it at 135% to get it stable. I guess I'll play around with the curve more. Thanks.

    Im not familiar with your card but i always thought all 1080Ti's had a 120% power limit. So if you can put 135% into your OCing software then that may well be your issue, the card will throttle when it hits the power draw limit so use the curve to keep it below that point.

    Run a windowed stress test with the power curve visible so you can see the power draw bounce around dependant on whats onscreen.

    Using the power curve is also a great way to lower temps if you are happy with a set core speed. If you are happy with say 1900mhz but have high temps (that may cause throttling) then just use the curve to drop the voltage at 1900mhz until you lose stability.

    Again a fictitious set of setting may be.
    1.3v and 1900mhz = 80c (stable, thermal throttling).
    1.25v and 1900mhz = 70c (stable, no thermal throttling).
    1.2v and 1900mhz =65c (unstable, no thermal throttling)

    Ultimately and rather annoyingly, watercooling wont guarantee you any more speed as the card has two factors that limit speed, both thermal AND power draw. So WCing removed the thermal limit but not the power draw limit. all 1080Ti are the same in that respect (unless you use various bios tricks).

    Anyone notice a 50% reduction in vulkan and dx12 drawcalls? I just noticed a huge drop on windows 10 regardless of what drivers I try. Dx11 remains unaffected.
    Nevermind, removing my video card and putting it back in fixed it. Cat must have knocked it loose. I thought I was going insane for a second.

    Anyone else here under-volting their 1080Ti?? I just gave it a try and I must say I'm impressed!! Card runs soo much cooler now.. this was near the start of the run but only hit 51C by the end of it. Not to mention it didn't change voltage/speeds at all the entire run!

    1924Mhz @ 0.950v! :D

    No but on certain (older) games il put VSync on to limit to 60fps which drops core speed and temps by a lot. COH2 and Empire/Napoleon Total War spring to mind

    Well I'm gonna post this again with more detail of what I have for an overclock right now in hopes that someone can help me out here because I'm really stuck. With this overclock, boost 3.0 has me throttling down to 1974mhz from 2ghz after a few minutes. Open to any suggestions on what to try. I've seen the tips on here for the voltage curve and did my own fiddling around but had no luck at all with the voltage curve. But then again I'm new to this kind of overclocking.
    Here's what I got so far 100% stable:

    Have a Google for the Guru 3D YouTube video on setting up the voltage curve.

    Yeah I've seen a few videos including the one by Hilbert. No luck though. My card just doesn't seem to like overclocking this way.
