Released a month after the 9500 and 9600, the AMD Phenom X4 9600 BE uses the same naming convention as AMD's earlier dual core models. The BE (Black Edition) suffex denotes only one crucial difference between the two models. With an unlocked CPU multiplier, AMD has allowed comuter enthusiasts greater control over what speeds their processors run at. By tweaking it, along with the Hyper Transport, front side bus, memory timings, and the voltages of each individual component, a skilled overclocker can obtain performances unrivaled by more expensive, technically superior components.
