Intel® Desktop Board DX79TO
Extreme Series
ATX Form Factor
The Ultimate Workhorse!
Introducing the Intel® Desktop Board DX79TO, designed for professional
grade computing and to support the new Intel® Core™ i7 Processors
When Performance Counts
With the Intel® Desktop Board DX79TO,
Intel is at it again. Built with stability and
reliability in mind, performance users will
have the peace of mind needed to perform
critical compute-intensive tasks. The Intel
Desktop Board DX79TO provides break-
away performance in production and edit-
ing, as well as digital media rendering and
real-time audio/video preview capabilities.
The massive data throughput and support
for the Intel® Core™ i7 processor runs more
applications simultaneously, with less wait
time. The Trusted Platform Module (TPM)
provides extra platform integrity with se-
cure hardware authentication for the most
sensitive work environments.
BIOS Vault Technology protects the board
and provides fault tolerant and secure
firmware. Intel BIOS is protected from out-
side attacks and enables advance security
checks and balances. Fast Boot also speeds
through boot times and eliminates unneces-
sary delays. Intel® Extreme Memory Profiles
(Intel® XMP) is a performance-packed
expansion of the standard DDR3 memory
specification, enabling a robust and stable
solution for ultra-fast memory.

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. See www.intel.com/technology/
turboboost 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 specific hardware and software you use. For more information including
details on which processors support HT Technology, see www.intel.com/
info/hyperthreading.
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 specifications.
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 specific supported memory for this
motherboard, please visit www.intel.com/products/motherboard/ for more
details.
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 configurations. See
http://developer.intel.com/technology/intel64/index.htm for more information.
Intel
®
High Definition 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.
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 configuration and operating system.
