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

The Intel

D processor 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. 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
http://www.intel.com/products/processor_number
for details.
Intel

Extended Memory 64 Technology (Intel
®
EM64T) requires a computer system with a processor, chipset, BIOS, operating system, device
drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) without an Intel EM64T-enabled BIOS.
Performance will vary depending on your hardware and software configurations. See
http://www.intel.com/info/em64t
for more information including
details on which processors support EM64T or consult with your system vendor for more information.
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.
Contact your local Intel sales office or your distributor to obtain the latest specifications and before placing your product order.
