Why change the shape of the curve when undervolting?

[Werwulf]

Why pull a single point upwards and flatten off when you can just offset the entire curve upwards (i.e increase the 'core') until stable and then drop the powerlimit? From my experience the end result is exactly the same and you have the advantage of once your curve is in the most efficient place, you can pick your desired power/performance with just the power slider.

I'm just getting into GPU undervolting and that sounds like a very elegant way of doing it.

I just tried it and found that the minimum power limit on my card is 83% and that's not low enough to get back to stock clock speeds when the core is boosted (which is a nice problem to have!) So I had to reduce the core clock a little below my stable limit and apply the 83% power limit to get stock clock speed.

I was able to get the same performance with a lower voltage by using my higher stable core boost and flattening the curve manually, but the board power and temp were exactly the same as when using the lower core and power limit.
