AMD processors reached 7 GHz (Phenom II X4) with the help of liquid nitrogen , but the absolute record of frequency (8.308 GHz) is set using CPU Celeron.
Today AMD makes it clear that the situation is changing with the release of Zambezi processors. They are produced on 32 nm technology and the change should be beneficial for their ability to overclock with an adequate cooling.
In late August, a group composed of overclocker Macci (Sami Maekinen), Brian Chew MacLachlan (Brian McLachlan), Pete Hardman (Pete Hardman), Aaron Shradina (Aaron Schradin) and Simon 64NOMIS Solotko (Simon Solotko ) took part in a unique experiment in extreme overclocking of AMD FX series with eight cores.
Of a certain number of processors were selected seven copies with the lowest VID value , it took several days. Four processors in the group conquered the frequency of 8 GHz when cooled with liquid nitrogen to minus 180 degrees Celsius. Later they were joined by eight processor capable of operating at a frequency of 8,429 GHz when cooled with liquid helium to minus 230-235 degrees Celsius and vcore 2.016 V. This processor allowed AMD to announce a new absolute record for overclocking which was officially registered in the Guinness Book of Records!
It should be noted that from the selected group of processors, many copies were overclocked without any problems up to 5 GHz, using air coolers .
Configuration was as follows : Motherboard ASUS Crosshair V Formula, CPU AMD FX-8150, one RAM Corsair Dominator GT DDR3-1772 2GB 9-9-9-27 timings and default voltage 1.65 V, video card AMD Radeon HD 6570, Windows 7 Ultimate (64-bit version), power supply, Antec power 1200W. The processor reached frequency 8429 MHz with two active core.
