Finding the optimum multiplier?

Does anyone know the optimum multiplier (ie: the point where the FSB/Memory starts to bottleneck the CPU)? I remember this test performed on the original Athlon and the P3. The P3 began to show memory bandwidth limitations at 7x multiplier and the Athlon at around 6x (or 12x single rate RAM). As the processor speed increases, latency and other parasitic effects may raise this number higher.

Assume DDR memory with 2-2-2-6T

Can someone point me to an answer?

What I want to know is the point where an Athlon XP begins to be cramped by its memory bus. In other words, the point where its performance scales disproportionately to its increase in clock speed for a given memory bus.
