1 Warning: Altering c lock freque ncy and/or volt age may (i) reduc e system
stability and useful li fe of the system and p rocessor; ( ii) cause the pr ocessor
and other system compone nts to fail; (iii) c ause reducti ons in system per for-
mance; (iv) cause additio nal damage; and (v) af fect system dat a integrity.
Intel has not tested, and doe s not warranty, the o peration of th e processor
beyond its specication s.
2 Intel® Turbo Boost Techno logy require s a PC with a proce ssor with
Intel Turbo Boost Technology c apability. Inte l Turbo Boost Technol ogy
performance varie s depending on h ardware, soft ware, and overa ll system
conguration. Check wi th your PC manufactur er 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 oper ating system. Per formance w ill vary depe nding on
the specic hardware and sof tware you use. For more inf ormation inclu ding
details on which processors support HT Technology, see www.intel.com/
info/hyperthreading
4 Maximum peak memo ry bandwidt h requires four D DR3 modules t o
be populated in each of the bl ue memory sl ots. DDR3 2400 m emory
support on this motherboard requires advanced knowledge of BIOS and
memory tuning; individu al results may vary. For spec ic supported me mory
for this motherboard, please visit www.intel.com/products/motherboard/
for more details.
5 Intel® High Deniti on Audio requires a syste m with an appropriat e Intel®
chipset and a motherboard with an appropriate codec and the necessary
drivers installed. System sound quality will vary depending on actual imple-
mentation, controlle r, codec, drivers, and sp eakers. For more infor mation
about Intel® HD Audio, refer to www.intel.com/design/chipsets/hdaudio.htm.
6 64-bit computing on Intel® architecture requires a computer system with a
processor, chipset, BI OS, operating s ystem, device dr ivers, and app lications
enabled for Intel® 64 architecture. Proces sors will not op erate (includi ng 32-
bit operation) without an Intel 64 architecture-enabled BIOS. Performance
will vary depending on your hard ware and software c onguration s. See
http://developer.intel.com/technology/intel64/index.htm for more information.
7 System resources a nd hardware (suc h as PCI and PCI Exp ress*) require
physical memory address locations that can reduce available addressable
system memory. This coul d result in a reduc tion of as much as 1 G B or more
of physical addressable memory being available to the operating system and
applications, depend ing on the system congu ration and operat ing system.
