1.3.1 Product highlights

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/packagings to safeguard

consumers’ health while minimizing the impact on the environment.

Intel® Core™2 Extreme / Core™ 2 Quad / Core™2 Duo Processor 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.

Intel P45 Chipset

The Intel® P45 Express Chipset is the latest chipset designed to support dualchannel DDR2 800 / 667 architecture, 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.

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.See page 2-18 for details.

Serial ATA 3 Gb/s technology and SATA-On-The-Go

This motherboard supports hard drives based on the Serial ATA (SATA) 3 Gb/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 andSee pages 2-22 and 2-26 for details.

1-2 Chapter 1: Product Introduction

Dual RAID solution

The Intel® ICH10R chipset incorporates six Serial ATA connectors with high performance RAID 0, 1, 5, and 10 functions, and the Marvell another two external Serial ATA connectors for RAID 0 and 1 functions, making this motherboard an ideal solution to enhance hard disk performance and data back up protection without the cost of add-on cards.

controller provides

Dual Gigabit LAN solution

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. SeeSee page 2-22 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 2-22 and 2-28 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 that simultaneously sends different audio streams to

different destinations. You can now talk to your partners on the headphone while playing multi-channel network games. See page 2-22 for details.See page 2-22 for details.

ASUS P5Q WS 1-3

1.3.2 ASUS unique features

ASUS Express Gate

Taking only 5 seconds to go online from bootup, Express Gate is the one-stop

gateway to instant fun! It’s a unique motherboard built-in OS. You can utilize the

most popular Instant Messengers (IM) like MSN, Skype, Google talk, QQ, and Yahoo! Messenger to keep in touch with friends, or quickly check on the weather and e-mails just before leaving your house. What’s more, the user-friendly picture manager lets you view your pictures without entering Windows at any time! See pages 3-41 and 4-31 to 4-39 for details.

The actual boot time depends on the system conguration.

ASUS Power Saving Solution

ASUS Power Saving solution intelligently and automatically provides balanced computing power and energy consumption.

ASUS EPU-WS Engine

The new ASUS EPU—the world’s rst power saving engine, has been

upgraded to a new WS-engine version, which provides total system power savings by detecting current PC loadings and intelligently moderating power in real-time. With auto phase switching for components (which includes the CPU, VGA card, drives, and system fan), the EPU automatically provides the most appropriate power usage via intelligent acceleration and overclocking— helping save power and money. See pages 4-21 to 4-24 for details.

ASUS 3rd Generation 8-Phase Power Design

The ASUS 3rd Generation 8-Phase Power Design provides highly efcient

operation to generate less heat (at least 18°C (32.4°F)) than other conventional power solutions. It reduces input ripple current and output ripple voltage, which keeps CPU and power module from suffering the risk of high power stress. It has the advantages of quick transient response and stability,

especially benecial when CPU requires more current immediately under

heavy loading or overclocking mode.

AI Nap

With AI Nap, the system can continue running at minimum power and noise when you are temporarily away. To wake the system and return to the OS environment, simply click the mouse or press a key. See page 4-27 forSee page 4-27 for details.

1-4 Chapter 1: Product Introduction

ASUS Workstation Features

ASUS Workstation features provide complete support to system maintenance and storage technology.

G.P. Diagnosis card

Bundled with P5Q WS motherboard (retail version), the G.P. Diagnosis card assists users in system checking by effortlessly and quickly providing precise system checks right after they switch on their PCs. See page 2-36 for details.

ASUS SASsaby cards support

This motherboard is fully compatible with ASUS SASsaby cards (optional). Faster, safer and more stable, SAS will provide users with a better choice for storage expansion and upgrade needs.

ASUS Quiet Thermal Solution

ASUS Quiet Thermal solution makes system more stable and enhances the overclocking capability.

Fanless Design—Heat-pipe solution

The Heat Pipe design effectively directs the heat generated by the chipsets to the heatsink near the back IO ports, where it can be carried away by existing

airow from CPU fan or bundled optional fan. The purpose of the innovative

heat pipe design on this motherboard is that the groundbreaking fanless design does not have lifetime problems as a chipset fan does. Furthermore, it

provides options for users to install side-ow fan or passive cooler. The Heat

Pipe design is the most reliable fanless thermal solution to date.
