Hyper-Threading 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.
64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device
drivers and applications enabled for Intel(R) 64 architecture. Processors will not operate (including 32-bit operation) without an
Intel(R) 64 architecture-enabled BIOS. 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 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.
Not all specified units of this processor support Enhanced HALT State and Enhanced Intel SpeedStep
®
Technology. See the
Processor Spec Finder at http://processorfinder.intel.com or contact your Intel representative for more information.
