1080ti maintain boost clock

benjii · 29 Jul 2017 at 10:33

I have a Gigabyte Aorus 1080ti Xtreme and I'm struggling to maintain the boost clock. I've set power limit to 150% and temp target to 90c, but it still begins to downclock at 70c. With a custom fan curve, the temperature tops out at 75c. Is there anyway to maintain the boost clock without making the fan curve more aggressive to keep it under 70c?

Afaik there isn't as gpu boost 3 lowers the top boost clock by about 13mhz, every 5 or so degrees above 40C. These numbers are all from the top of my head but you get the idea.

That makes sense. Tinkering, I've managed to fend off the downclocking quite a lot. However, it drops from 1974Mhz to 1962Mhz once it reaches 70c. I realise that's hardly anything, but I was more curious on whether or not it could be stopped.

Sorry not trying to hijack thread..

I wonder if the same is happening to me in game..after a short while the FPS will drop a bit, is that from throttling because of temps? Fan curve is set to manual, and peaking at 70c 'ish..im on a "blower" style 1080ti btw..

FPS will drop based on frequency. Usually when you start and the card is cool, it will usually run at a very high boost clock, then gradually reduce the boost clock as it get's warmer. As your running a custom fan profile though, it should settle in when it reach's 70 degrees or so.

Having said that, should not really be massive changes in fps %, talking a couple of % mostly, but can likely confirm running something like GPU-Z in the background and seeing what the frequency graph look's like.

Thanks for that, I have quite an aggressive fan curve on my ti, with peak temps on BF1 at 62c..a bit loud but I wear a headset anyways.

i've noticed that when fans speed increases it makes my clocks go down. if i set my fans to 100% it will not boost as high as with fans @40% .. but my EVGA has 112% power limit :/

I am just wondering, the 1080ti consumes a lot of power and all that heat is getting dumped in the case. Have you tried linking your case fan speeds to your GPU temperature to try to get rid of all that hot air so it doesn't just re-circulate within the case? Course it depends on the rest of your cooling arrangements, but it may well make a very significant difference.

I was using a blower cooler, so 90% of the heat was being expelled out the back anyway..plus I have now sold my 1080ti and gonna get a VEGA 64 middle of the month..
