Shortly AMD CPU cannot gain anything from a fast memory.
THIS is how you run benchmarks... I've adjusted the multiplier (It's an AMD thing, you wouldn't understand) to keep the clock speed as close to 2.0 Ghz as possible and haven't changed the timing of the RAM at all so that we're only testing the difference that memory bandwidth makes.
(The following scores will be given with 166x12 first, and 200x10 below.
*EDIT* 200x11 scores are highlighted.
**EDIT** 200/166 @ 2.0Ghz scores are given next to the 200x10 sync results
***EDIT*** 221/166 @ 2.21 Ghz in Italics)

How does this translate to more real world performance?

So AthlonXP's don't benefit from increased memory bandwidth huh?
For sh!ts n giggles, I'll run the same tests at 200x11 (2.2 Ghz) a little later.
*EDIT* Edited for 2.2 Ghz scores.
**EDIT** Edited for 200/166 async @ 2.0 Ghz
***EDIT*** Edited for P4 style overclocking... 221/166 async @ 2.21 Ghz
