reports German overclockers got their hands on three Phenom II samples and managed to overclock one of the chips to 5925MHz with LN2 cooling and the chip running at a voltage of 1.9V.
Thanks to extreme cooling they could even run benchmarks like the 3DMark 06 with more than 5 GHz. By their own account they achieved a "respectable result” with the overclocked Phenom II processor. The key to success were the low operation temperatures of partly under -190 °C.
"SoF"‘s CPU caused problems while overclocking under -160 °C because the used mainboard, Foxconn's A79A-S, missed an important function: The Phenom II processors only tolerate lowest temperatures if the HT clock is restricted to about 1,000 MHz.
