Undervolting 1080 Ti

Which voltage do you think the best in terms of performance to temperature ratio for daily use? (I'm not looking for maximum performance as possible) ?

1835 @ 850mv is pretty good.  Neither of my two 1080Ti's are completely stable at 1830MHz unless they're using 875mv.

 

Honestly, you could probably go for 875mv or 900mv and push around 1900MHz and still cut your power draw by at least a good 20%. 875mv cuts the power draw by almost 30%, which is definitely a significant reduction in power. IMHO, as long as you can undervolt to +/- 875mv at similar clock speeds as the default settings under full load, then you're doing pretty good.

So guys I'm a newbie in terms of overclocking and stuff, I'm trying to lower the temps on my Asus Strix 1080 Ti so that this thing can run in almost silent.

 

Should I undervolt the card to the point where it barely crash or I need to lower the clock a bit for it to become stable?

My ambient temperature is around 29C so its a bit hot and the card goes to around 74C if I don't turn on the air conditioner. So I really want to make this thing cooler :D 

 

Thanks guys !

Just turn down the power limit the card will do the rest.

Lowering the power limit will lower the clock without adjusting the voltage curve. This is completely different from undervolting.

That is not undervolting at all, in fact voltage is locked on Pascal by normal means.

On Vega it turns down the voltage, strange for Pascal then, but in any event is there much point in undervolting on pascal? Doesn't GPU boost do it's own thing anyways?

Yeah maxing out the power bar helps out with GPU Boost 3.0 since it increases the max temp as far as I am concern, haven't really bothered trying to undervolt it, running my on stock only the power bar max out which is already all the power I currently need xD

I'm benching right now and I was able to achieve 2025MHz @ 1.000mv and 1911MHz @ 900mv.

 

Thanks Man for your inputs!

I'm just trying to get the best temps to performance ratio. At stock, my 1080 Ti reach only 1747 @ 1000mv+ and it ran crazily hot.

 

Thanks anyway for stopping by!

GPU boost simply boosts the clock if thermals and power allows. It doesn't do anything with voltages.

 

Also, yes, there's a pretty valid point in undervolting. It allows you to both significantly reduce power consumption and stabilize your frame rate. It also, in theory, allows you to boost much higher if you edit your clock/voltage curve correctly.

Hey mate. What did you settle with in the end with your voltage config? I just bought a 1080 ti strix OC and the coil whine is driving me nuts. Asus suggested that I undervolt the card to reduce it, LOL!

Hey man, my config for the past 5 months for the 1080Ti is 1911 mhz @900mv. Hope it can help you!
