immediately.
• To avoid short circuits, keep paper clips, screws, and staples away from
connectors, slots, sockets and circuitry.
• Avoid dust, humidity, and temperature extremes. Do not place the product in
any area where it may become wet.
• Place the product on a stable surface.
• If you encounter technical problems with the product, contact a qualied
service technician or your retailer.

Intel®Core™2 Extreme / Core™2 Quad / Core™2 Duo
CPU support
This motherboard supports the latest Intel®Core™ 2 Extreme / Core™ 2 Quad /
Core™ 2 Duo processors in the LGA775 package. It is excellent for multi-tasking,
multi-media and enthusiastic gamers with 1600/1333/1066/800 MHz FSB. The
Intel®Core™ 2 series processor is one of the most powerful CPUs in the world.
This motherboard also supports Intel®CPUs in the new 45nm manufacturing
process. See page 2-7 for details.
Intel P45 Chipset
The Intel®P45 Express Chipset is the latest chipset designed to support dual-
channel DDR2 1200/1066/800/667 architecture, 1600/1333/1066/800 FSB
(Front Side Bus), PCIe 2.0, and multi-core CPUs. It especially includes Intel®
Fast Memory Access technology that signicantly optimizes the use of available
memory bandwidth and reduces the latency of the memory accesses.
Dual-channel DDR2 memory support
To attain top performance, ASUS engineers have successfully unleashed the
true potential of DDR2 memory. While in DDR2 1200 mode, ASUS’s exclusive
technology offers a choice of FSB 1600, providing great performance for 3D
graphics and other memory demanding applications.
PCIe 2.0
This motherboard supports the latest PCIe 2.0 device for twice the current speed
and bandwidth. This enhances system performance while still providing backward
compatibility to PCIe 1.0 devices. See page 2-18 for details.

ASUS Maximus II Formula 1-3
ATI CrossFire™ Technology
ATI’s CrossFire™ boosts image quality along with rendering speed, eliminating
the need to scale down screen resolution to get high quality images. CrossFire™
allows higher antialiasing, anisotropic ltering, shading, and texture settings. Adjust
your display congurations, experiment with the advanced 3D settings, and check
the effects with a real-time 3D-rendered previews within ATI Catalyst™ Control
Center.
Serial ATA 3.0 Gb/s technology and SATA-On-The-Go
This motherboard supports the next-generation hard drives based on the Serial
ATA (SATA) 3Gb/s storage specication, delivering enhanced scalability and
doubling the bus bandwidth for high-speed data retrieval and saves. The external
SATA port located at the back I/O provides smart setup and hot-plug functions.
Easily backup photos, videos and other entertainment contents to external devices.
See pages 2-22, 2-25, and 2-26 for details.
Dual Gigabit LAN
The integrated dual Gigabit LAN design allows a PC to serve as a network
gateway for managing trafc between two separate networks. This capability
ensures rapid transfer of data from WAN to LAN without any added arbitration or
latency. See page 2-21 for details.
IEEE 1394a support
The IEEE 1394a interface provides high speed digital interface for audio/video
appliances such as digital television, digital video camcorders, storage peripherals
& other PC portable devices. See pages 2-21 and 2-27 for details.
High Denition Audio
Enjoy high-end sound quality on your PC! The onboard 8-channel HD audio (High
Denition Audio, previously codenamed Azalia) CODEC enables high-quality
192KHz/24-bit audio output, jack-sensing feature, retasking functions, and multi-
streaming technology that simultaneously sends different audio streams to different
destinations. You can now talk to your partners on the headphones while playing
multi-channel network games. See pages 2-21 for details.

1-4 Chapter 1: Product Introduction
Green ASUS
This motherboard and its packaging comply with the European Union’s Restriction
on the use of Hazardous Substances (RoHS). This is in line with the ASUS vision
of creating environment-friendly and recyclable products/packaging to safeguard
consumers’ health while minimizing the impact on the environment.
1.3.2 ROG Intelligent Performance & Overclocking features
Speeding HDD
Without drivers or BIOS setups, the ROG exclusive Speeding HDD is ideal for
anyone who needs to secure data on their hard drives or enhance hard drive
performances without the hassles of complicated congurations. With Speeding
HDD’s friendly graphical user interface, users can easily arrange hard drive
backups or enhance their hard drive transfer rates, making sure that data is looked
after every moment, every day. See pages 2-26, 3-28, and 4-33 for details.
Pin-Fin Thermal Module
Compared with traditional stacked-n heatpipe solution, the new-generation pin-n
thermal design results in better thermal performance, which enlarges the “heat-
exchange” surface area and breaks the “boundary-layer” phenomenon for effective
airow. The Pin-Fin Thermal Module is the most efcient thermal system on the
motherboard.
CPU Level Up
Ever wish that you could have a more expansive CPU? Upgrade your CPU at no
additional cost with ROG’s CPU Level Up! Simply choose a processor you want to
OC to, and the motherboard will do the rest for you. See the new CPU speed and
enjoy the performance instantly! Overclocking is never as easy as this. See pages
