Help with 2070 Super Undervolting and frequency

[Nick1881]

So I saw some videos about undervolting the GPU to lower temps, I like the sound of this as it would also reduce my CPU temps by lowering overall case temps, also hopefully less heat blasting out of my case.

My card is the Gigabyte Windforce OC version with clocks of 1785Mhz, but MSI afterburner reports 1980Mhz as per the attached, but when I run Heaven it reports 1920Mhz.

GPU-Z reports different too, it seems to state the correct boost clock but in sensors tab it also says 1920Mhz.

Am I just not understanding it correctly?

The Nvidia cards boost until the thermals hit a certain limit then the clocks decrease in 15Mhz increments. That's pretty normal behaviour TBH.

Try 1980 at 1000mv and flatten each point after that, if that's stable you could try 1980mhz at 975mv and even 950mv may be stable if it's a good chip.

Thanks guys, was just a bit worried it was running way over what it's meant to.

Currently 1920Mhz at 975mV is stable, 950mV and it will crash on COD:MW.

pointless tbh

the 2070 super runs extremely cool as it is. no need to make it run cooler. if your case and cpu are getting too hot then there is an issue with your case or cpu cooler tbh.

My temps are actually really good, but so far I’ve trimmed a little more off my GPU temp, low 60’s now in game.

Of course that hot air exhausts into my room and with the weather getting warmer I’d like to minimise the AC usage.

It isn't pointless in the summer months, you can shave up to 5c off your load temp at a lower fan speed in some cases.

At default if your card initially boosts to around 1980mhz like mine does but then drops down to 1920mhz after a while in game, it actually makes more sense to use the curve in afterburner, as you can achieve a higher consistent clockspeed at a lower voltage and temperature. Example being my 2070 super that will stick at 1995mhz at 1000mv and never drops below that.

You're on a forum where people tweak things to the nth degree, a few degrees saved and anywhere from 20-60 watts less power draw, depending on the RTX card, isn't to be sniffed at.

i just set my power limit to 95 and then overclocked it

i then upped to 100 and i couldn't get it any faster. so left it on 95.

tbh msi afterburners automatic overclock and curve editor does a really good job. i think I only got it a 5-10 mhz faster manually which in the grand scheme of things isn't worth the time and effort. it won't overclock memory though iirc. you have to do that manually.

the point is 10 series cards ran 20C hotter than the 20 series. so if a reduction of 20C isn't enough then issues lie elsewhere.

my old card used to run 85C this one 65C and I have never heard the fans either it's on silent they don't ramp up because they aren't needed.
