Editing Overclocking (section)

===Factors allowing overclocking===
Overclockability arises in part due to the economics of the manufacturing processes of CPUs and other components. In many cases components are manufactured by the same process, and tested after manufacture to determine their actual maximum ratings. Components are then marked with a rating chosen by the market needs of the semiconductor manufacturer. If [[Semiconductor device fabrication#Device test|manufacturing yield]] is high, more higher-rated components than required may be produced, and the manufacturer may mark and sell higher-performing components as lower-rated for marketing reasons. In some cases, the true maximum rating of the component may exceed even the highest rated component sold. Many devices sold with a lower rating may behave in all ways as higher-rated ones, while in the worst case operation at the higher rating may be more problematical.

Notably, higher clocks must always mean greater waste heat generation, as semiconductors set to high must dump to ground more often. In some cases, this means that the chief drawback of the overclocked part is far more heat dissipated than the maximums published by the manufacturer. Pentium architect [[Bob Colwell]] calls overclocking an "uncontrolled experiment in better-than-worst-case system operation".<ref>{{cite journal|first1=Bob|last1=Colwell|title=The Zen of Overclocking|journal=[[Computer (magazine)|Computer]]|volume=37|issue=3|date=March 2004|pages=9–12|publisher=[[Institute of Electrical and Electronics Engineers]]|doi=10.1109/MC.2004.1273994|s2cid=21582410}}</ref>
