AMD Phenom II X4 overclocked to more than 6 GHz
Yesterday AMD Phenom II X4 CPUs that were cooled with liquid nitrogen got overclocked. AMD had organized an event and invited the famous extreme overclockers "Sampsa” and "SF3D”.
All tested chips could be overclocked to more than 6.1 GHz clock speed and were run with around 1.95 Volt. As 6 GHz were stable with the 3DMark 05 and 06 the Crysis CPU test even ran with 6.1 GHz.
One example could even be overclocked to 6,280 MHz - with all four processor cores. For record attempts it is common practice to deactivate single CPU cores in order to achieve even higher frequencies. Furthermore "Sampsa” assumes that the achieved results are not the maximum for the Phenom II X4. However, the overclocker only published one CPU Z screenshot which shows a CPU clock speed of 6,045.7 MHz.
With common air cooling (Cooler Master Z600) the Finnish OC experts could also achieve 4.13 GHz at 1.58 Volt in the Crysis benchmark. For a continuous operation this voltage might be too high, though.
"Sampsa” and "SF3D” were not allowed to publish the benchmark results in the Xtremesystems forum. They used a reference motherboard by AMD as well as a Gigabyte GA-MA790GP-DS4H with 790GX chipset.
