AMD Stepping Guide @ AthlonOC

This is a comprehensive guide explaining how the codes on the CPU core
effect the overclockability of the CPU.

Here is a quote:

"After seeing the huge amount of speculation about AMD step-codes and what
they mean to overclockers we decided to bring some light on to the subject .
We will draw our conclusions based on a database of over 1000 AMD CPUs,
their step code, and overclocked speeds. The database has been compiled over several months. This, we believe, is the most accurate manner in which to
derive results and a basic understanding of the codes used by AMD."
