24332G—October 2003
The purpose of the AMD Athlon™ Processor Model 6 Revision Guide is to communicate updated product
information on the AMD Athlon processor model 6 to designers of computer systems and software
developers. This revision guide applies to the AMD Athlon processor model 6, mobile AMD Athlon
processor model 6, and AMD Athlon MP processor model 6. This guide consists of three sections:
■ Product Errata: This section, which starts on page 5, provides a detailed description of product
errata, including potential effects on system operation and suggested workarounds. An erratum is
defined as a deviation from the product’s specification. A product errata may cause the behavior of
the AMD Athlon processor model 6 to deviate from the published specifications.
■ Revision Determination: This section, which starts on page 18, shows the AMD Athlon processor
model 6 identification numbers returned by the CPUID instruction for each revision of the
processor.
■ Technical and Documentation Support: This section, which starts on page 19, provides a listing of
available technical support resources. It also lists corrections, modifications, and clarifications to
listed documents. Please refer to the data sheets listed in this section for product marking
information.
Revision Guide Policy
Occasionally AMD identifies deviations from or changes to the specification of the AMD Athlon
processor model 6. These changes are documented in the AMD Athlon™ Processor Model 6 Revision
Guide as errata. Descriptions are written to assist system and software designers in using the
AMD Athlon processor model 6 and corrections to AMD’s documentation on the AMD Athlon
processor model 6 are included. This release documents currently characterized product errata.

1 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.
