2080 Ti undervolting help

Recommended Posts

Posted · Original PosterOP

I have a 2080 TI founders edition and I want to undervolt for better temps. What would be a safe voltage to go for? Also any other help would be appreciated as I've never undervolted a GPU before

As low as you want, but tbh it's better to "undervolt" by lowering the power limit and raising the core clock offset.

What do you mean? Like what should I do?

Drop the power limit to a point which gives a temperature and fan noise (fan curve manually adjustable) you want, then raise the memory clock offset and then core clock offset to its highest stable state.

Is the power limit like usage limit? Like if user it to 80% will my GPU never load past 80%?

no, power limit limits power draw instead of usage. When the GPU hits the power limit, it reduces frequency and voltage.

Here is the difference in temps between 80%,100% and 130% on my EVGA XC 2080 ti.

In Heaven usage is about the same but frame rate is jumps with more power.

 

 

80% is silent. I can't hear the 2080 ti over the CPU cooler fans.

100% is quiet. These are the settings I use to keep most of my games over 60fps ultra at 4k.

130% is very noisy. In games like Assassin's Creed Odyssey the noise is unbearable without headphones.
