Overclocking
And now to the part where we're supposed to find out if there's any truth in AMD's rumor, the so-called 'headroom'. We can translate the word to OC-potential, which has quite frankly been one of the old Phenom-series of processors major disappointments.
We managed to bump the Phenom II X3 720 Black Edition up to 3750 MHz - which was achieved by changing the following settings in the BIOS:
- Multiplier 14 -> 15
- Bus-speed 200 -> 250 MHz
- HT Link 2.0 GHz -> 2.5 GHz
- vCore 1.35 -> 1.55v
- This is a 34% increase of clock-frequency compared to the standard speed. Lets see how the numbers change accordingly.
