PATENT, COPYRIGHT OR OTHER INTELLECTUAL PROPERTY RIGHT. Intel products are not intended for use in medical, life saving, or
life sustaining 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 5500 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.
Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family,
not across different processor families. See
http://www.intel.com/products/processor_number
for details. 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.
Hyper-Threading Technology requires a computer system with a processor supporting HT Technology and an HT Technology-
enabled chipset, BIOS and operating system. Performance will vary depending on the specific hardware and software you use. For
more information including details on which processors support HT Technology, see
http://www.intel.com/products/ht/hyperthreading_more.htm
Enabling Execute Disable Bit functionality requires a PC with a processor with Execute Disable Bit capability and a supporting
operating system. Check with your PC manufacturer on whether your system delivers Execute Disable Bit functionality.
64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device
drivers and applications enabled for Intel® 64 architecture. Performance will vary depending on your hardware and software
configurations. 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 computer system software enabled for it. Functionality, performance or other benefits will vary
depending on hardware and software configurations and may require a BIOS update. Software applications may not be compatible
with all operating systems. Please check with your application vendor.
Intel® Turbo Boost Technology requires a PC with a processor with Intel Turbo Boost Technology capability. Intel Turbo Boost
Technology performance varies depending on hardware, software and overall system configuration. Check with your PC
manufacturer on whether your system delivers Intel Turbo Boost Technology. For more information, see
www.intel.com.
Enhanced Intel SpeedStep® Technology. See the
http://processorfinder.intel.com
or contact your Intel representative for more
information.
Contact your local Intel sales office or your distributor to obtain the latest specifications and before placing your product order.
