overclock: /oh'vr-klok'/ vt. To operate a CPU or other digital
logic device at a rate higher than it was designed for, under the
assumption that the manufacturer put some slop into the
specification to account for manufacturing tolerances. Overclocking
something can result in intermittent crashes, and can even burn
things out, since power dissipation is directly proportional to
clock frequency. People who make a hobby of this are sometimes
called "overclockers"; they are thrilled that they can run their
450MHz CPU at 500MHz, even though they can only tell the difference
by running a benchmark program.
