Benchmarks: Overclocking Performance
Overclocking both of these AMD processors was rather simple, having them operating at 3.90GHz with a few quick tweaks. In order to get the Phenom II X2 550 running stable at this frequency we increased the core voltage to 1.50v and the clock multiplier from 15.5x to 19.5x. Remember this is a Black Edition processor which in mundane terms means it's multiplier unlocked.
The Athlon II X2 250 had to use a FSB boost to 260MHz in order to reach a stable 3.90GHz overclock. The voltage was also increased to 1.50v.
Overall we saw decent performance gains provided by the overclock at the cost of power consumption. Although both processors were clocked at the same frequency, the Phenom II X2 550 still provided a considerable performance advantage for the most part.
