Intel products are not intended for use in medical, life saving, life sustaining, critical control or safety systems, or in nuclear facility
applications.
Intel may make changes to specifications and product descriptions at any time, without notice.
Designers must not rely on the absence or characteristics of any features or instructions marked “reserved” or “undefined.” Intel
reserves these for future definition and shall have no responsibility whatsoever for conflicts or incompatibilities arising from future
changes to them.
The Intel® Xeon® Processor 7400 Series may contain design defects or errors known as errata which may cause the product to
deviate from published specifications. Current characterized errata are available on request.
Contact your local Intel sales office or your distributor to obtain the latest specifications and before placing your product order.
Technology requires a computer system with an Intel® processor supporting HT Technology and a Hyper-
Threading Technology enabled chipset, BIOS and operating system. Performance will vary depending on the specific hardware and
software you use. See http://www.intel.com/products/ht/hyperthreading_more.htm/ for more information including details on
which processors support HT Technology.
Intel® 64 (Formerly Intel® EM64T) requires a computer system with a processor, chipset, BIOS, operating system, device
drivers and applications enabled for Intel 64. Processor will not operate (including 32-bit operation) without an Intel 64 enabled
BIOS. Performance will vary depending on your hardware and software configurations. See http://www.intel.com/technology/
64bitextensions/ for more information including details on which processors support Intel 64 or consult with your system vendor
for more information.
Intel® Virtualization Technology requires a computer system with an enabled Intel® processor, BIOS, virtual machine monitor
(VMM) and for some uses, certain platform software enabled for it. Functionality, performance or other benefit will vary depending
on hardware and software configurations. Intel Virtualization Technology-enabled BIOS and VMM applications are currently in
development.

Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor
family, not across different processor families. Over time processor numbers will increment based on changes in clock, speed,
cache, FSB, or other features, and increments are not intended to represent proportional or quantitative increases in any particular
feature. Current roadmap processor number progression is not necessarily representative of future roadmaps. See www.intel.com/
products/processor_number for details.

Nomenclature
Errata
are design defects or errors. These may cause the Intel® Xeon® Processor
7400 Series’s behavior to deviate from published specifications. Hardware and software
designed to be used with any given stepping must assume that all errata documented
for that stepping are present on all devices.
Specification Changes
are modifications to the current published specifications.
These changes will be incorporated in any new release of the specification.
Specification Clarifications
describe a specification in greater detail or further
highlight a specification’s impact to a complex design situation. These clarifications will
be incorporated in any new release of the specification.
