I have a gigabyte gaming oc rtx 3080. Tried to oc with offset. Above 1950 core boost games start to freeze or crash. Power limit etc is all way unlocked. Can undervolting get me above 2 ghz? My highest temp was 68c. Or that’s just the limit of my gpu?

Offset is a rather inefficient way to OC. You could have 60MHz headroom at 1880MHz, but only 50MHz headroom at 1900MHz. So you crash. If you want something easy, just reset all settings to defaults and run the OC Scanner. Use the latest Nvidia drivers and the latest Afterburner.
Oc scanner was disappointing too. Put it at 1850 :(
How? Was it the clock speed you were getting in games? It can happen if the voltage was set high.
But it adjusts the entire curve, not a specific point. So the clocks would be shifting depending on GPU load.
Yeah but the whole curve of it was very little ahead of the orginal one. Superposition didn’t gain much this way. I’ll mby try to do my one curve if get the nerve someday.
You don't really need to do the whole curve. Even the OC Scanner is doing 4 areas. So you can do maybe two - one is the highest clock speed you get in games with standard power limit, and another 100-150 MHz lower. Anything lower than that won't be heavily used in demanding games anyway.
And, yes, the results from the OC Scanner can be underwhelming, but they're also very stable.
Uh that's not what's supposed to happen.
Did you unlock voltage control before you run OC Scanner? Also ensure to update to the latest stable version, it uses Nvidia driver-level API to tune the card.
You can definitely try. You won't get higher than max clock speed but you might be able to hold max clock speed or close to that. This would lead to a higher avg clock speed which hands more fps in the end. Especially low fps situations get a boost.
My goal was a quite gpu while still performing over stock.
I set my 3070 to 925mV 1905mhz. I could go further but don't want to spend much time testing right now. It results in more than stock performance and only around 2% off of max oc while the gpu is cool af. I set a really quite fan curve and the gpu only uses 130-175w in games at 1440p. Temps are mostly in the low 60's. In BFV in which the GPU only pulls 130w the gpu stays below 60°C.

You likely won't get a higher maximum boost frequency when you undervolt since you'll be feeding even less voltage to the GPU.
However, where undervolting can help and potentially even give you a performance boost is through stabilizing your boost clock, giving you a higher average frequency.
With my undervolt, my GPU boost frequency is pretty much constant. And because it's constant, my overall performance is actually better than stock because the boost clock doesn't dip as low as it used to. You can maybe choose 1950MHz as a starting point and go down from there. As long as you stay above where your GPU frequency settled previously when OC, you'll get the same or even more performance.
