I have a RTX 3070ti Founders Edition. I know these run hotter than normal (around 82-84 degree under load gaming) so I wanted to try under-volting it. I ideally don't want to lose any performance as that is what you pay for but wanted to see how low I could get the voltage (temperature).
I watched a few tutorials on overclocking and there seems to be two methods using MSI Afterburner:
1) You increase the core clock to get the speed on the voltage you require then drag the remainder down and apply to keep them on the constant curve. This seems to be the preferred option as although you may use a lower clock speed the effective speed shown in HWInfo is more accurate to this.
2) You reduce the core clock by -200 then drag one point up to what you need and apply to also keep the remainder in a line.

I have been testing using method two all day and here is what I found:

Am I right in saying what I followed is correct? MSI Afterburner default curve, pick the voltage target point and whatever the core is subtract that from my target then add this amount to the core clock. This puts that at the correct point then I SHIFT+DRAG to highlight the rest, drag down and apply to put them all in a straight line at this point.
I then tested in Superposition (1080p Extreme) and kept an eye on speeds/temps with HWInfo. If it passed I then tried playing Diablo 4 as this seems to be good at detecting bad overclock/undervolts.

Going by this it seems my best point is the 0.925 @ 1890mhz. I know others will have better undervolts but it seems to be a lottery with them. The 0.900@1840 has better temps but I am giving up some performance by the looks of the Superposition scores.

Just want to make sure I am doing this correct rather than collecting false data :)
Or if I should be doing the Method 1 way instead?

Also finding it weird now on stock settings if I run Superposition 3 times I get completely different results each time (8665/8607/8577). Is that normal?

Cheers
