Intel DP55KG - Desktop Board Extreme Series... Reference guide

ATX Form Factor
Intel®Desktop Board DP55KG
Extreme Series
Performance tuning for greater
control
An Intel-designed BIOS1presets clock
values for quick performance tuning, along
with great manual controls. The six-phase
voltage regulators with sturdy thermal
solutions and CHiL* Advanced Digital
Voltage Regulator Control deliver high-
speed phase control for lower, efcient,
and balanced temperature. An onboard
post code decoder LED cycles through post
codes while booting. The third-generation
watchdog timer recovers from crashes
by restoring previous safe values. If the
watchdog timer fails, the easy-to-access
Back-to-BIOS switch lets you get to main-
tenance mode without having to open the
system chassis.
Surviving never looked this good
The Intel Desktop Board DP55KG is built
with the new Intel® P55 Express Chipset,
supporting the Intel® Core™ i7 and Intel®
Core™ i5 processors in the LGA1156 pack-
age. The revolutionary two-chip layout
enables lower power consumption and
more advanced performance tuning1for
a smoother, more realistic experience.
Intel® Extreme Memory Proles (Intel® XMP)
is a performance-packed expansion of the
standard DDR3 memory specication,
hitting speeds of 1600 MHz1or faster.
Eight SATA and two eSATA ports deliver
greater exibility. Build your system quickly
with 90-degree rotated SATA ports and
easy-to-locate, aligned front-panel headers
at the edge of the board. An integrated
Bluetooth* module onboard connects
to peripherals.
Loaded with the features extreme
gamers want
When it comes to serious gaming, the
Intel® Desktop Board DP55KG is packed
with features to exceed any power user’s
expectations. With incredible support for
up to eight threads of raw processing power,
dual-channel DDR3 memory, and exible
support for ATI* CrossreX* technology and
NVIDIA* SLI* technology, the Intel Desktop
Board DP55KG brings the best weapons
to any application or game. The exible
graphics also make this board ideal for the
backbone of an entry workstation system.
Today’s extreme gaming, digital photography,
and video editing demand breakthrough
technology. The Intel Desktop Board DP55KG
supports the latest processors, and Intel’s
cutting-edge technology delivers even
greater performance and power efciency.

DDR3 1600 or higher memory support requires compatible Intel® XMP-enabled memory or advanced knowledge of BIOS and memory tuning; individual results may vary. Altering PC memory frequency and/or
voltage may (i) reduce system stability and use life of the system, memory and processor; (ii) cause the processor and other system components to fail; (iii) cause reductions in system performance; (iv)
cause additional heat or other damage; and (v) affect system data integrity. Intel assumes no responsibility that the memory, included if used with altered clock frequencies and/or voltages, will be t for
any particular purpose. Check with memory manufacturer for warranty and additional details. For specic supported memory for this motherboard, please visit www.intel.com/go/idb for more details.
2 Intel® Desktop Control Center is only compatible with Intel® Desktop Boards based on the Intel® X38 Express Chipset and newer. Auto-tuning capabilities may not be available for all Extreme Series motherboards.
3 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/turboboost for more information.
4 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.
5 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.
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 implementation, controller, codec, drivers, and speakers. For more information about Intel® HD Audio, refer to www.intel.com/design/chipsets/hdaudio.htm
7 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.
