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®Core™ i7-900 desktop processor Extreme Edition series and Intel®Core™ i7-900 desktop processor 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.

ΔIntel 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

Intel®64 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 www.intel.com/info/em64t 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 a processor, chipset, 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 VMM applications are currently in development.

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.

Enhanced Intel® SpeedStep Technology. See the Processor Spec Finder or contact your Intel representative for more information.

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.
