overclocking
/ˌoʊvərˈklɒkɪŋ/
CommonRunning a CPU, GPU, or RAM faster than its factory-set speed to get more performance.
In hardware communities, overclocking carries a DIY tinkerer reputation. Successfully overclocking and sharing results is a badge of technical competence. Badly overclocking is a rite of passage.

Use it when
- Running a processor or graphics card above its rated clock speed.
- Discussing squeezing more performance from existing hardware.
- Talking about the risks, cooling requirements, or results of running hardware above spec.
Do not use it when
- You mean updating firmware or drivers to improve performance.
- You mean enabling manufacturer-provided boost modes like PBO or XMP.
