Strategy

The P4 2000A features a 20.0× multiplier, once again enabling a higher core operating speed with a lower front side bus. That's good if you're trying to push the core speed to the max, without stressing subsystems that are driven by the FSB, but it may offer lower overall system performance as compared to using a slightly higher FSB and a slightly lower processor core operating speed. If you're aiming for 2400 MHz, the 1600A or 1800A will therefore yield greater overall performance due to their higher FSBs, along with comparable stability, depending on voltage, cooling, and your particular processor sample.
