Editing Overclocking (section)

===Underclocking===
{{Main|Underclocking}}
Conversely, the primary goal of [[underclocking]] is to reduce power consumption and the resultant heat generation of a device, with the trade-offs being lower clock speeds and reductions in performance. Reducing the cooling requirements needed to keep hardware at a given operational temperature has knock-on benefits such as lowering the number and speed of fans to allow [[Quiet PC|quieter operation]], and in mobile devices increase the length of battery life per charge. Some manufacturers underclock components of battery-powered equipment to improve battery life, or implement systems that detect when a device is operating under battery power and reduce clock frequency.<ref>{{cite web |title=What is an underclock? |url=https://www.lenovo.com/us/en/glossary/underclock/ |website=Lenovo |access-date=19 March 2025}}</ref>

Underclocking and undervolting would be attempted on a desktop system to have it operate silently (such as for a home entertainment center) while potentially offering higher performance than currently offered by low-voltage processor offerings. This would use a "standard-voltage" part and attempt to run with lower voltages (while attempting to keep the desktop speeds) to meet an acceptable performance/noise target for the build. This was also attractive as using a "standard voltage" processor in a "low voltage" application avoided paying the traditional price premium for an officially certified low [[voltage]] version. However again like overclocking there is no guarantee of success, and the builder's time researching given system/processor combinations and especially the time and tedium of performing many iterations of stability testing need to be considered. The usefulness of underclocking (again like overclocking) is determined by what processor offerings, prices, and availability are at the specific time of the build. Underclocking is also sometimes used when [[troubleshooting]].<ref>{{cite web |title=What is an underclock? |url=https://www.lenovo.com/us/en/glossary/underclock/ |website=Lenovo |access-date=19 March 2025}}</ref>
