Just a few weeks after the official launch of AMD's first processors based on the Bulldozer architecture, an overclocker has managed to reach a new CPU frequency world record by utilizing the chip maker's flagship desktop processor, the FX-8150.
The record was achieved by cooling the CPU with liquid nitrogen which has a boiling point of -192°C.
This sort of cooling was required for the CPU in order to allow the overclocker to raise the voltage of the chip all the way to an impressive 1.992V.
Thanks to this vCore the FX-8150 was able to reach 8,461.51 MHz with a bus speed of 272.95MHz and a 31.0X multiplier.
To put things in perspective, the eight-core AMD flagship processor used by Andre Yang (the enthusiast behind this new WR) has a base clock of 3.6GHz and a maximum Turbo Core frequency of 4.2GHz, so this translates into a 235% core speed increase over the chip's stock settings.
The rest of the system used for this overclock was comprised out of a high-end Asus Crosshair V Formula motherboard, 2GB of Corsair DDR3 system memory running at 909.8MHz (1818.16MHz DDR) with timings of 9-9-9-24T and an Nvidia GeForce GTX 580 graphics card.
Only two out of the eight computing cores were active during this experiment.
The highest frequency achieved by a CPU until this new record was set also belonged to an FX-8150 processor that in mid-September was overclocked to an impressive 8,429MHz by an AMD sponsored team of enthusiasts.
Liquid helium was used for that overclock and the CPU used was back then the world's fastest clocked processor, surpassing by 120MHz the previous world record.
This new world record however comes to show that Bulldozer has even higher overclocking headroom left, and things are probably going to be even better once the new B3 stepping will be launched by AMD.
