What it means
Feeding a chip slightly less voltage to do the same work. Less voltage means less heat, and less heat often means higher sustained clocks.
More detail
On a part that throttles when it gets hot, a good undervolt can be a quiet win — cooler, sometimes faster, often quieter fans. The risk is stability: too little voltage causes crashes that can take ages to trace back, so it's a measure-and-stress-test job, not a set-and-forget one. …
