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.

2 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

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.

3 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.

6 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.
