Overclocking a GTX 1080ti on air.

QwerkyPengwen · Oct 28, 2018

So I found this post for messing with the voltage curve in MSI-A.
But it's clearly for water. There is something in there about it working on air too, but I want to be sure I have all the information I need before messing with stuff.

So far, typically the only overclocking I do is with MSI-A and by just adjusting the offsets and messing with fan curve.

But since Pascal has a nasty issue with stepping the voltage down when it doesn't need to and fluctuating a lot, I wanted to see what I could do to get it to stay more consistent and stay at a higher value in order to maintain a higher consistent clock speed.

My card is an EVGA GTX 1080ti SC Black Edition.

I will be cooling this card on air.

So far, when under load and at about 70% fan speed, I settle in at about 62c so I have room to go up in voltage and clocks.

Any help in regards to whether or not this is a viable thing to do on air, and if so a more in depth guide to adjusting the voltage curve, or even if flashing a different bios would help as well is greatly appreciated.

Here's what I found online for the voltage curve.

This guy also has a neat little post about flashing BIOS to get more performance.

For practical purposes you can typically increase voltage all the way (it won't actually go that far because Nvidia limits voltage on their cards except for some like the EVGA FTW and others like that, and even still they are limited just not as much.)

I wouldn't consider a bios mod for a gaming card. If you were going to make more money mining, then maybe. But bios flashes are risky and not recommended, plus they void your warranty.

Not what I was asking about but thanks for the input.

I know the cards are voltage limited. And I always unlock voltage and put the slider to max.
My issue is that the card steps down the voltage and fluctuates it a lot in it's attempt to "keep things balanced" when it comes to core speed, voltage, power, and temps.

This stepping down and fluctuating of voltage inevitably causes my core speeds to fluctuate and drop heavily.

I want to keep them more consistent and make them stay at their higher values by keeping the voltage more consistent and at it's higher value.

Has nothing to do with mining, and I'm not modding the BIOS, I was looking into flashing another stock BIOS from something like the FTW3 card in order to achieve more consistent values with my voltage and clock speeds.

I personally don't care about the warranty.
