[Discuss] Cool Processing

[mark at buttery.org (Shirley Márquez Dúlcey)]

Undervolting is the flip side of overclocking. Both count on the fact
that a typical CPU has some operational margin; it does a bit better
on the speed/voltage curve than the specs guarantee. Most motherboards
that enable overclocking can also be undervolted; it's something to
explore if you are building a quiet system for home theater or the
like, or if you just like the idea of saving energy.
