An overclocker has managed to rather substantially increase the world's frequency record for Advanced Micro Devices' central processing units (CPU) at an overclocking contest hosted by Gigabyte Technologies, one of the largest makers of mainboards.
Utilizing Gigabyte GA-890FXA-UD7 mainboard, the overclocker who calls himself Mad222 from Hong Kong managed to overclock AMD Phenom II X4 965 Black Edition processor (3.40GHz) to whopping 7344.48MHz. The computer performance enthusiast used dry ice for cooling. The mainboard was not modified, according to the overclocking.
Based on the "hall of fame" of validated CPU-Z overclocking records, Mad222 substantially increased the overclocking bar for any AMD microprocessor with 7344.48MHz clock-speed as the others are rather substantially behind the leader with 7217.81MHz (Phenom II X4 955), 7153.89MHz (Phenom II X4 955), 7140.39MHz (Phenom II X4 955) and 7127.85MHz (Phenom II X4 955). Gigabyte also claims that two other overclockers, who participated in the contest and used Gigabyte GA-890FXA-UD7 mainboards managed to hit 7182.04MHz and 7168.7MHz clock-speeds.
Overclocking microprocessors by almost 100% from their official frequency is not truly uncommon in the world of hardcore overclockers. However, when overclocked, those chips can barely perform any actual job and usually overclockers only run SuperPi test suite. Moreover, systems cooled down using liquid nitrogen or other extreme methods cannot be used for prolonged periods of time. As a result, overclocking records are just records and do not have a lot of practical meaning other than showing reliability of CPUs, mainboards and/or other components.
The world's highest CPU frequency ever reached is 8242.45MHz. The record was set using Intel Celeron 360 microprocessor and Asus Commando mainboard.
