AMD’s Phenom II processors are truly mean overclockers under extreme cold, but with more conventional cooling the processors are yet to really impress. They are still much better than the last series of Phenoms, but compared to Intel’s Core architecture they are still several MHz short. AMD overclockers have started looking for The Golden One among Phenom II processors and we now hear about a Phenom II X4 processor that does 4.4GHz with air cooling and “only” 1.55V.
The overclock was with all four cores, but and the air was a bit colder than normal (processor temperature was about 25°C) and the memories downclocked to reach 4.4GHz. The system was just stable enough for a CPU-Z screendump but it still shows that the Phenom II architecture can reach respectable frequencies with regular air cooling.
