Legal Lines and Disclaimers
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 E5 Product Family 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.
Copies of documents which have an order number and are referenced in this document, or other Intel literature may be obtained
by calling 1-800-548-4725 or by visiting Intel's website at
http://www.intel.com.
See the Processor Spec Finder at http://ark.intel.com or contact your Intel representative for more information.
Requires an Intel® HT Technology enabled system, check with your PC manufacturer. Performance will vary depending on the
specific hardware and software used. Not available on Intel® Core™ i5-750. For more information including details on which
processors support HT Technology, visit http://www.intel.com/info/hyperthreading
Requires a system with Intel® Turbo Boost Technology. Intel Turbo Boost Technology and Intel Turbo Boost Technology 2.0 are only
available on select Intel® processors. Consult your PC manufacturer. Performance varies depending on hardware, software, and
system configuration. For more information, visit http://www.intel.com/go/turbo
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® Trusted Execution Technology: No computer system can provide absolute security under all conditions. Intel® Trusted
Execution Technology (Intel® TXT) requires a computer system with Intel® Virtualization Technology, an Intel TXT-enabled
processor, chipset, BIOS, Authenticated Code Modules and an Intel TXT-compatible measured launched environment (MLE). Intel
TXT also requires the system to contain a TPM v1.s. For more information, visit http://www.intel.com/technology/security

C is a two-wire communications bus/protocol developed by Philips. SMBus is a subset of the I
2
C bus/protocol and was developed
by Intel. Implementations of the I
2
C bus/protocol may require licenses from various entities, including Philips Electronics N.V. and
North American Philips Corporation.
