Help needed for undervolting 3060ti

[Mazer]

I been seeing some high temps on my 3060ti and repasted it yesterday which was needed as it was getting too hot gaming (87c!) before now it's still getting a bit hot seems to settle around (76c) but saw it getting to 80C so I looked up some videos on undervolting. The problem I keep having is no matter what I set the undervolt in msi afterburner it causes instability where everything freezes on screen to driver crashing when using heaven benchmark on the background. Tried at 1900mhz @ 900mv and not stable also tried 1860mhz @ 850mv as I seen the core stable that in gaming. Can anyone help if I'm doing it right which block do I pull down?

Or just do +150Mhz on the core clock, hit apply, then :

My Asus TuF 3060 Ti is stable at 1905 MHz on the core with 950 mV undervolt.

This ofc depends on each card but for me this works the best so I left it this way.
I've also repasted my card a few months ago and this way it stays between 60-65 celsius '23-25 celsius room temp' even when completely stressed 'Cyberpunk with RT for example' and fan speed between 1300-1500 rpm.

I've used both methods of Nvidia undervolting/overclocking mentioned above. One thing I'd add to droopyRO's technique is: after setting +150MHz on the Core Clock, then set your Power Limit to 90 or 80 or 75%. This will accomplish the undervolt and limit your power use and thus your temperatures. Even 80% power with the +150 Core Clock will likely get you higher core clocks at lower power (thus lower temps) than your default settings. I use this technique (lol those exact settings) on my 1050 Ti to control temperatures.

If you prefer to set a MHz line in the sand like Sithaer does, just drag your Core Clock to the lowest value, open the curve editor (Ctrl-F) and drag the 950mV level to 1905MHz and hit Save. Your numbers are more undervolted than Sithaer's and may be stable under some lighter loads (why you see them sometimes) but not heavier loads (when the card adjusts to another level).

FWIW, Sithaer's settings are very close to what I use on my 1080.

Yup, I've also tried to go lower and while it was stable for a while under lighter loads it kept crashing in Cyberpunk or Plague Tale Requiem.
Maybe I could tinker with it further but honestly its fine with me, I rather have it rock stable than have some insignificant gains.

I did what you suggested and got this: Now I just run games and see if it's stable how long would you say it takes to know if the undervolt was stable?

it's stable how long would you say it takes to know if the undervolt was stable?

Just try all your most demanding games.

Depends on the game but in games that stress the card enough it crashed on me in a few minutes or less if it wasn't stable.

Cyberpunk is a good high load and I could pretty dependably get Ark to crash out when I pushed my 1080 just a bit too far. Pretty much any DX12 eye-candy title. You could loop the Time Spy or Superposition benchmarks but they don't seem to cause the same instantaneous high demands like actual games do. Those are what cause the crashes if your undervolt is too low.

Never had to do that, the power consumption drops by default when you lower the voltage.

My cards will boost higher and deliver more fps (not a lot more, but some) because they're running at their power limits before the undervolt. Reduce the power consumption with the UV and the card boosts clock speed to bring the power consumption back to the limit. If I'm capping my fps (depends on the game whether I do this) then I see a real nice reduction in power consumption at the same clock speed and fps after the undervolt.

The increase in fps from undervolting (and/or overclocking) is so small (usually ~5%) relative to the reduction in power usage when limiting fps to the same speed (usually 25-35%) that I almost always go for the undervolt-and-cap, not the overclock-and-max-power.
