1-17

USB 2.0 technology

The motherboard implements the Universal Serial Bus (USB) 2.0 specification, dramatically increasing the connection speed from the

12 Mbps bandwidth on USB 1.1 to a faster 480 Mbps on USB 2.0. USB 2.0 is backward compatible with USB 1.1. See pages 2-24 and 2-28 for details.

Gigabit LAN solution

The motherboard comes with a PCI Express Gigabit LAN controller to provide a total solution for your networking needs. The Gigabit LAN controller uses the PCI Express segment to provide faster data bandwidth. See pages 2-23 to 2-24 for details.

Temperature, fan, and voltage monitoring

The CPU temperature is monitored by the ASIC (integrated in the Winbond Super I/O) to prevent overheating and damage. The system fan rotations per minute (RPM) is monitored for timely failure detection. The ASIC monitors the voltage levels to ensure stable supply of current for critical components. See pages 4-33 and 4-34 for details.

1-18	Chapter 1: Product introduction

1.3.2 ASUS AI Lifestyle features

AI Quiet

The ASUS AI Quiet function dynamically controls CPU speed and reduces temperature and fan speeds, thus minimizing noise and ensuring quiet operation. See page 4-33 for details.

AI Overclocking

This feature allows convenient overclocking up to 30% (depending on the installed CPU and DRAM) to enhance system performance while maintaining system stability. See page 4-19 for details.

ASUS WiFi -g™ (Wireless Edition only)

ASUS WiFi-g™ is an IEEE 802.11g-compliant wireless LAN adapter that allows data transmission of up to 54 Mbps using the 2.4 GHz frequency band. ASUS provides full software application support and a user-friendly wizard to help you set up your wireless LAN effortlessly. The ASUS WiFi-g™ is backward compatible with IEEE 802.11b devices.

See pages 2-23 and 2-24 for details.

1.3.3 Innovative ASUS features

Precision Tweaker

This feature allows you to fine-tune the CPU/memory voltage and gradually increase the Front Side Bus (FSB) and PCI Express frequency to achieve maximum system performance. See pages 4-20 and 4-21 for details.

PEG Link Mode

This feature enhances your PCI Express graphics card performance by allowing the motherboard to automatically adjust the PCI Express graphics link mode to the correct frequency based on the system configuration.

Four additional settings are available for overclocking the PEG Link Mode. See page 4-26 for details.

ASUS Hyper Path 3

This feature significantly shortens latency time during data transfers, allowing users to experience the real power of their computers. See page 4-26 for details.

ASUS P5LD2 SE

1-19

CPU Lock Free

This feature allows you to adjust the CPU multiplier to 14x. Setting the appropriate BIOS setting automatically reduces the CPU multiplier value for more flexibility when increasing external FSB. See page 4-23 for details.

CrashFree BIOS 2

This feature allows you to restore the original BIOS data from the support CD in case the BIOS codes and data are corrupted. This protection eliminates the need to buy a replacement ROM chip. See page 4-5 for details.

ASUS Q-Fan technology

The ASUS Q-Fan technology smartly adjusts the fan speeds according to the system loading to ensure quiet, cool, and efficient operation.

See pages 4 33 and 4-34 for details.

ASUS MyLogo2™

2.1Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.

•Unplug the power cord from the wall socket before touching any component.

•Use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity.

•Hold components by the edges to avoid touching the ICs on them.

•Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

•Before you install or remove any component, ensure

that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, or components, or all of the above articles.

Onboard LED

The motherboard comes with a standby power LED. The green LED lights up to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you should shut down the system and unplug the power cable before removing or plugging in any motherboard component. The illustration below shows the location of the onboard LED.

2.2Motherboard overview

Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it.

Make sure to unplug the power cord before installing or removing the motherboard. Failure to do so can cause you physical injury and damage to the motherboard components.

2.2.1 Placement direction

When installing the motherboard, make sure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis as indicated in the image below.

2.2.2 Screw holes

Place seven (7) screws into the holes indicated by circles to secure the motherboard to the chassis.

Do not overtighten the screws! Doing so can damage the motherboard.

Place this side towards the rear of the chassis

2.3Central Processing Unit (CPU)

The motherboard comes with a surface mount LGA775 socket designed for the Intel® Pentium® D, Pentium® 4 and Celeron® processor in the 775-land package.

•Upon purchase of the motherboard, make sure that the PnP cap is

on the socket and the socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket contacts/motherboard components. ASUS shoulders the repair cost only if the damage is shipment/ transit-related.

•Keep the cap after installing the motherboard. ASUS will process Return Merchandise Authorization (RMA) requests only if the motherboard comes with the cap on the LGA775 socket.

•The product warranty does not cover damage to the socket contacts resulting from incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP cap.

2.3.1 Installing the CPU

To install a CPU:

1.Locate the CPU socket on the motherboard.

To prevent damage to the socket pins, do not remove the PnP cap unless you are installing a CPU.

3.Lift the load lever in the direction of the arrow to a 135º angle.

4.Lift the load plate with your

	thumb and forefinger to a 100º	B
