TechnicalSpecications
1
Warning: Altering clock frequency and/or voltage may (i) reduce system
stability and useful life of the system and processor; (ii) cause the processor
and other system components to fail; (iii) cause reductions in system perfor-
mance; (iv) cause additional damage; and (v) affect system data integrity.
Intel has not tested, and does not warranty, the operation of the processor
beyond its specications.

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
conguration. Check with your PC manufacturer on whether your system
delivers Intel Turbo Boost Technology. See www.intel.com/technology/turbo-
boost for more information.

Intel
®
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 specic hardware and software you use. For more information including
details on which processors support HT Technology, see www.intel.com/
info/hyperthreading
4
Maximum peak memory bandwidth requires four DDR3 modules to
be populated in each of the blue memory slots. DDR3 2400 memory
support on this motherboard requires advanced knowledge of BIOS and
memory tuning; individual results may vary. For specic supported memory
for this motherboard, please visit www.intel.com/products/motherboard/
for more details.
5
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. Processors will not operate (including 32-
bit operation) without an Intel 64 architecture-enabled BIOS. Performance
will vary depending on your hardware and software congurations. See
http://developer.intel.com/technology/intel64/index.htm for more information.

Intel
®
High Denition Audio requires a system with an appropriate Intel
®
chipset and a motherboard with an appropriate codec and the necessary
drivers installed. System sound quality will vary depending on actual imple-
mentation, controller, codec, drivers, and speakers. For more information
about Intel
®
HD Audio, refer to www.intel.com/design/chipsets/hdaudio.htm.
7
System resources and hardware (such as PCI and PCI Express*) require
physical memory address locations that can reduce available addressable
system memory. This could result in a reduction of as much as 1 GB or more
of physical addressable memory being available to the operating system and
applications, depending on the system conguration and operating system.
