Whats the point of undervolting in my case ?

[Speedy]

Hey guys, i hope you are having a good day .

i wanted to undervolt my gpu, i went and undervolted the gpu from 1.05v to about 0.940 v , then it didn't change the tepms, i thoght the point of undervolting is to lower the temps.

im i missing something here ?

i have a 2080 super with i5 10400f and 16gb ram

the only thing that it changes is less wattage, i would only do that for the CPU but GPU? waste of FPS

[_I_]

lower core voltage is more efficient (same performance less power)
but its also less stable

it would be lower wattage with the same fan speeds

what was the fan pwm or rpm before and after the change?

if it was 60c and 50% fan before and 60c with 0% fan now, thats huge change

will be blunt....a friend was having problems with his EVGA 2080 ti and was hitting 107c on the hot spot.....he ended up reapplying thermal paste to the GPU and got it back down to about 72c on the hotspot......

lets face it.....this card is at least 5 years old at this point....repaste it......

Undervolting is useful. Be careful not to do it too much or a lot of things will start to just become less efficient (not in terms of power draw, but the capabilities of the gpu with what it's struggling with), and the lower voltage to the gpu might just make whatever it is running, to close unexpectedly. Find a game that runs at the highest possible fps. Now cap the fps to whatever will be a near constant fps, no matter what is on screen. Since you have done this to whatever game or program that generates the most fps and is gpu intensive, you can use that benchmark as a guide for what fps limits you should set in other games. This will help control your temps, without sacrificing noticeable performance, especially if it's a single player game and you're getting over 100fps, 100fps is plenty.

Good examples for me was saving 30C in temperature on my gpu when I limited my fps to 100 instead of 160 in Bladur's Gate 3, and also another 30C decrease in temperature, by limiting fps to 100 instead of 150 in rdr2.

really ? i'v seen some people get -3 degrees to -5 at some point, thats really important for me as i live in a very hot environement

Oh, i honestly didn't notice that, will do some tests later and see difrences

yeah, you are spot on, there is no denying my gpu is kinda starting to be obsolete, yes it runs everything but like you put it, it is time to repaste i guess

Very good advice, i take the same approach as you do in single player games, but as you know, in multiplayer you need to squeez every last drop especially in fps games which i really like to play.

i guess ill take the same route and cap my fps, it is very hot where i live and my gpu is a 2 fan gpu, maybe thats another factor to consider

Just use something like Afterburner, and tell it to prioritize temps, and set the limit you want, such as 75 C

that would limit the gpu drasticallly no ?

Maybe yes, maybe no. Depends on how low you set the temp limit. Won't be nearly as bad as trying to under volt yourself though.

If I used something like that and set the temps to 70 C I saw a performance hit. If I set it to 75C, it ran perfectly with no issues at all. Just experiment and find the best temp-to-performance setting for your own setup.

And I cap a lot of my games at 60 FPS anyway (I prefer consistent FPS versus higher-but-variable, probably because I used to play a lot of fighting games). My games could have ran at higher FPS anyway, so I didn't loose anything, since I was capping at 60 anyway.

and temperature too my bad i forgot to type that

With a proper undervolt your card draws less power, runs cooler, and gains performance.

I was looking in to this for my CPU, the other day, and read something interesting.
Your GPU may well be using less power, but unless you have changed your fan curve, your temperatures may not change at all.
This is because the fan is set by temperature, so it can still reach the same temperatures as before, just the fan is working less.
What you need to do is adjust the fan curve.

That's all I know, lol.

that works only on AMD
