Core Voltage - Lowered To 1.2 Volts

Our 65 nm sample of the Phenom processor operated at a core voltage of 1.225 Volts. When the processor switches to power saving mode, the voltage is reduced to 1.050 Volts. The BIOS still offers core voltage options to facilitate overclocking.

Temperatures

We used the Zalman CNPS9700 LED to cool the Phenom 9700 CPU, stressing it by running the multi-threaded version of Prime95 for half an hour. With the fan running at full speed, the CPU temperature reached 38°C. Reducing the fan speed resulted in a temperature of 45°C. When idle, the CPU stayed rather cool at only 32°C.

good review but you should have had included more result of the overclocked phenom. i just want to know how much juce i you can push out of it for me it is a must it beats the 6400+ otherwise its not worth purchasing in my opinion, it just has to beat its older generation when its running at same clocks.that is why amd has to work on its clock speed and cache. hopefully deneb will be out soon. i would also realy appriciate it to see some review about the phenom 9850 black edition compared against both the 6000+ 6400+ and q6600 and q9300 and maybe some e8xxx model. with overclocked results. pushed it to the maximum. would be realy cool hehe :)
