There's a fair margin possible with clock speeds and also voltages. It's not like the millions of transistors in a CPU all suddenly stop working once you go 0.5% above or below the published specs... but push it far enough and all it takes is for ONE to stop working properly to cause a crash... you just need to find that point then back it off slightly to keep your system stable.

I managed to undervolt a low end E1200 by 30% (1.325v -> 0.900v) and it was still going (at full stress/load) 24 hours later. The beauty of undervolting is that it saves on power and cooling costs without affecting performance.
