Caveats

The primary admonition of overvolting is added heat: the ability blown by a ambit increases with the aboveboard of the voltage applied, so even baby voltage increases decidedly affect power. At college temperatures, transistor achievement is abnormally affected, and at some threshold, the achievement abridgement due to the calefaction exceeds the abeyant assets from the college voltages. Overheating and accident to circuits can action actual bound if application top voltages.

There are aswell longer-term concerns: assorted adverse device-level furnishings such as hot carrier bang and electromigration action added rapidly at college voltages, abbreviating the lifespan of overvolted components.
