An anonymous reader writes to tell us Phoronix has posted an article that covers the basics of GPU and CPU overclocking utilities available for Linux. From the article: "In 2005 we had featured several articles on the state of NVIDIA graphics card overclocking under Linux. In early 2005 the only option for Linux users was NVClock. The open-source NVClock was started by Roderick Colenbrander in 2001 and since then has been evolving. However, coming out in June of 2005 from the NVIDIA camp was CoolBits support for their alternative operating system drivers."
