On this page we present the history of overclocking

Brief Overview of Overclocking History

Years 1980s

During the mid 1980s liquid nitrogen was used in the development of new micro-processors. In a documentary broadcasted in 1984,[1], the use of liquid nitrogen for the development of supercomputers in Japan is explained as a method to address the heat produced by micro-processors operating at high frequency.

Years 1990s

Years 2000s

Major Events

2005: The Great Texas Overclocking Competition

Following their Bullhead graphics card launch, ATI hosted an overclocking competition in Dalles, Texas, USA, featuring some of the world's best overclockers at the time[2]. Macci from Finland, Oppainter from United States and Fugger from the United States were invited to test out Radeon X850XT 512MB. The trio reached clock frequencies of up to 850MHz on the core and 700MHz on the memory, paired with an AMD FX55 running very near at 4GHz.

2007: Plaisio Overclocking Super Event

On Saturday October 20, 2007, the Greek distributor hosted an overclocking event featuring three of the best overclockers at the time: Hipro5 (Greece), Shamino (Singapore) and K|ngp|n (USA)[3].

Main article: Broadwell-E overclocking

Broadwell-E is the successor to the Haswell-E processor architecture from Intel. The platform launched on May 30, 2016, at Computex, one of the largest IT tradeshows in the world held in Taipei Taiwan. The flagship Core i7 6950X processor was shown at the HWBOT World Tour 2016 Asia stop. Broadwell-E is produced using Intel's 14nm manufacturing process. At launch the Broadwell-E architecture set 4 World Records, 15 Global First Places. The Broadwell-E processors are most renowned for being the first 10-core overclockable CPU for consumers.

2017: Kaby Lake

Main article: Kaby Lake overclocking

Kaby Lake is the successor to the Skylake processor architecture from Intel. The platform is due to launch early 2017. The Kaby Lake architecture is very similar to Skylake and is the 'O' in Intel's PAO (process, architecture, optimization) development process.

World Records

Starting from the early 2000s, much of the attention for overclocking was focused on overclocking World Records.



Super PI is a computer program that calculates pi to a specified number of digits after the decimal point—up to a maximum of 32 million. It uses Gauss–Legendre algorithm and is a Windows port of the program used by Yasumasa Kanada in 1995 to compute pi to 232 digits. ([1])

The Overclocker (Magazine)

The Overclocker launched in 2008[31] as the very first magazine dedicated to overclocking. Nick Ross and Josh X quit their day jobs to work on the digital magazine which is freely available. The main goal was to serve the overclocking community with a monthly update on the latest news related to overclocking.

The official website launched on August 10, 2008. The content read: "We do not aim to compete with anyone so if you’ve got a relevant website, forum, community, event or product, we want to know about it. Think of us as a newsletter for the global overclocking community and the industry which supports it. Each month we’ll have news, interviews, reports on events and unbiased reviews of the latest hardware while publicizing the best posts from the forums that you already use. Sign up today! First issue is out next week!"

The first issue was published on ?. The second issue was published on August 19, 2008[32].

The latest edition of TheOverclocker magazine can be found on its website

87 Clockers (Manga)

87 Clockers is a cartoon by Tomoko Ninomiya, a well-known Japanese manga artist[33]. The story revolves around a music college student striving to become the best at overclocking. The first issue was released in June 2011 and continued to be published under the same label until November 2014. From 2015 forward, a new label picked up the manga.

A paperback version of Volume 1 of the manga was released in South Korea, Taiwan and Hong Kong in April 2012.

The Book of Overclocking: Tweak Your PC to Unleash Its Power

In January 2003 No Starch Press released the first edition of the book written by Scott Wainner. Scott founded the system optimization website Sysopt.com in 1994 while attending high school. The book's description reads[34]:

"The definitive guide to overclocking-- the art of running a PC's processor faster than the manufacturer intended. If you don't mind voiding the manufacturer's warranty on your CPU, overclocking is for you. Learn how not to fry your system while souping up everything from the Pentium II to the latest Athlon XP and Pentium 4. Sections on cooling, troubleshooting, and benchmarking make sure you get the most out of your machine."

The Screensavers

The Screensavers was an American TV show that aired from 1998 to 2005. The show centered around computers and technology. On several occasions the show would demonstrate extreme overclocking:

Futurama S06E25: Overclockwise

"Overclockwise" is the twenty-fifth episode of the sixth season of the animated sitcom Futurama, and originally aired September 1, 2011. In the episode, Bender is overclocked by Cubert Farnsworth, gradually becoming more powerful in computing ability, until eventually becoming omniscient and able to foresee future events.[35].

In the episode Cubert overclocks Bender to improve his performance in an online game. Walt, Larry, and Igner are defeated online by an enhanced Bender and complain to Mom, who has both Cubert and Professor Farnsworth arrested for overclocking Bender (a violation of Bender's license agreement). She also sends an army of robots to capture Bender so he can be reset to his original settings. Due to heightened intelligence caused by his overclocking, Bender is able to anticipate future probabilities and connects himself to a water cooler to prevent overheating. He anticipates the arrival of Mom's robots, and manages to destroy them and steal their processors, increasing his capacities even further. Bender then leaves Planet Express to find a new, larger coolant.[36]

The processing chip inside Bender's lower body is labelled an AMD Athlon II.[37]
