AMD Athlon™ Processor Model 6 Revision Guide

Preliminary Information

Product Errata

This section documents AMD Athlon™ Processor Model 6 product errata. The errata are divided into
categories to assist referencing particular errata. A unique tracking number for each erratum has been
assigned within this document for user convenience in tracking the errata within specific revision
levels. Table 1 cross-references the revisions of the processor to each erratum. An “X” indicates that
the erratum applies to the stepping. The absence of an “X” indicates that the erratum does not apply
to the stepping. Table 2 on page 6 cross-references erratum to each processor segment. An “X”
indicates that the erratum applies to the processor segment.

Note:

There can be missing errata numbers. Errata that have been resolved from early revisions of the
processor have been deleted, and errata that have been reconsidered may have been deleted or
renumbered.
