Man clocks Pentium Extreme to 5GHz
Gas-cooled 65nm Intel Extreme Edition 965, anyone?
Japanese enthusiasts have been treated to a demo of an Intel Pentium Extreme Edition 965 chip running at over 5GHz, a frequency 35.8 per cent higher than the part was designed to be clocked to. The chip usually runs at just 3.73GHz.
A peek inside the casing reveals Danish cooling specialist Asetek's VapoChill Extreme Edition II refrigeration system, using to pull the CPU temperature down to a mere 5°C. The 65nm, dual-core, HyperThreading-enabled 965 is fitted onto a standard Intel D975XBX motherboard.
According to a report on Japanese-language site Akiba PC Watch, which covered the demo, the CPU's voltage needs to be dropped from 1.5V to 1.42V before it can be overclocked to the 5.066GHz. ®
