Undervolting can lead to higher performance as well - for example, my 3080 Ti

Out of the box, it hits power limits and doesn't boost much past 1800/1850Mhz on the core, even in a water block.

Undervolting leads to a rock solid 1920Mhz for hours on end - less power, less heat, more performance.

I did a similar thing in the golden days with my AMD Athlon (Thoroughbred/B) processor.

It was 1400MHz out of the box, I clocked it to 2200MHz (200x11). None of the AMDs offerings ran at 2200MHz with 200x11 configuration, so it was blowing everything out of the water, with less heat and noise nonetheless.

Since x11 wasn't an extreme multiplier for it, I was running it slightly undervolted. That system is still running rock-solid even today, somewhere.
