Revision Guide
The purpose of the AMD Athlon™ Processor Model 4 Revision Guide is to communicate updated product
information on the AMD Athlon™ processor model 4 to designers of computer systems and software
developers. 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 4 to deviate from published specifications.
■ Revision Determination: This section, which starts on page 20, shows the AMD Athlon processor
model 4 identification numbers returned by the CPUID instruction for each revision of the
processor.
■ Technical and Documentation Support: This section, which starts on page 21, 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 4. These changes are documented in the AMD Athlon™ Processor Model 4 Revision
Guide as errata. Descriptions are written to assist system and software designers in using the AMD
Athlon processor model 4 and corrections to AMD’s documentation on the AMD Athlon processor
model 4 are included. This release documents currently characterized product errata, but is not
intended to identify all errata in the processor.
