Editing Underclocking (section)

==Advantages==
* Reduced electrical power consumption, especially when combined with [[undervolting]] (i.e., reducing the component's voltage below the nominal). For instance, by underclocking an [[Athlon XP]] 1700+ processor from 1466 to 1000&nbsp;MHz and reducing the core voltage from 1.75 to 1.15V, a computer user reduced the power consumption from 64.0 to 21.6W, i.e., 66% power reduction, with only 26% less performance.<ref>{{cite web|url=http://www.silentpcreview.com/article33-page1.html |title=Ultimate Underclock & Undervolt Project |website=Silentpcreview.com |date=2002-07-28 |access-date=2016-06-02}}</ref> The same is true for newer processors: When a single-core Intel CPU was 20% underclocked, the PC's performance was down only 13% with a 49% power reduction.<ref>{{cite web|url=http://www.datarespons.com/templates/interrupt.aspx?id%3D30477 |title=Fra overklokking til underklokking - Data Respons |access-date=November 27, 2010 |url-status=dead |archive-url=https://web.archive.org/web/20110708233710/http://www.datarespons.com/templates/interrupt.aspx?id=30477 |archive-date=July 8, 2011 }}</ref>
In general, the power consumed by a CPU with a [[capacitance]] ''C'', running at frequency ''f'' and voltage ''V'' is approximately<ref>{{cite web |title=Enhanced Intel SpeedStep Technology for the Intel Pentium M Processor - White Paper |publisher=[[Intel Corporation]] |date=March 2004 |url=http://download.intel.com/design/network/papers/30117401.pdf |url-status=live |archive-url=https://web.archive.org/web/20150812030010/http://download.intel.com/design/network/papers/30117401.pdf |archive-date=2015-08-12 }}</ref>

* Reduced heat generation, which is exactly proportional to the power consumption.
* Less [[noise pollution|noise]] because the [[cooling fan]]s may be slowed down, or even eliminated. A cooling fan's efficiency is proportional to its rotation speed, but as it increases, so does the noise.
* Longer hardware lifespan.
* Increased stability.
* Increased battery life.
* Better compatibility with old applications.
* Proper performance of very old computer games that were dependent on CPU timing.
