1.3 Special features

Latest processor technology

The motherboard supports dual Intel® Xeon™ Processors via 604-pin surface mount ZIF sockets. The processor has 1MB/512KB L2 cache, includes a 533/400MHz system bus, and features the Intel Hyper-Threading Technology that allows up to 3.2GHz core frequencies.

Dual-channel DDR333 memory support

Employing the dual-channel DDR memory architecture, the motherboard provides a solution that doubles the system memory bandwidth to boost system performance. The motherboard supports up to 4GB of system memory using PC2700/PC2100 ECC or non-ECC DDR DIMMs to deliver up to 5.33GB/s data transfer rate for the latest 3D graphics, multimedia, and Internet applications.

Serial ATA technology

The motherboard supports the new Serial ATA technology through the SATA interfaces and the Intel® 6300ESB ICH and Promise® PDC20378 controllers onboard. The SATA specification allows for thinner, more flexible cables with lower pin count, reduced voltage requirement, and up to 150MB/s data transfer rate.

Multi-RAID solution

The motherboard has the Promise® PDC20378 controller to support multiRAID solution using Serial ATA/150 hard disks. The RAID0 (striping), RAID1 (mirroring), and RAID 0+1 provide a cost-effective highperformance solution for added system performance and reliability.

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 fast 480 Mbps on USB 2.0. USB 2.0 is backward compatible with USB 1.1.

1-2

Chapter 1: Product introduction

Gigabit LAN solution

The Intel® 82547GI Gigabit Ethernet controller allows full-duplex Gigabit performance on LAN on Motherboard (LOM) applications through the Communication Streaming Architecture (CSA). Instead of connecting to the PCI bus, the controller connects to the dedicated CSA bus on the Memory Controller Hub (MCH) thus reducing the PCI bottlenecks by freeing the PCI bus for other I/O operations.

The Intel

82541GI Gigabit Ethernet controller is also onboard to support

32-bit LAN through the PCI bus.

ASUS PCH-DR motherboard

2.1 Before you proceed

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

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

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

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

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

5. 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, and/or components.

When lit, the green LED (SB_PWR1) indicates that the system is ON, in sleep mode, or in soft-off mode, a reminder that you should shut down the system and unplug the power cable before removing or plugging in any motherboard component.

This warning LED (LED1) lights up if you installed two CPUs of different type/voltage. You must install identical CPUs on this motherboard.

2.2 Motherboard installation

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 may cause you physical injury and damage 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 nine (9) screws into the holes indicated by circles to secure the motherboard to the chassis.

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

Place this side towards the rear of the chassis

2.3 Central Processing Unit (CPU)

2.3.1 Overview

The motherboard comes with dual surface mount 604-pin Zero Insertion Force (ZIF) sockets. The sockets are designed for the Intel® Xeon™ Processor in the 604-pin package with 1MB/512KB L2 cache.

2.3.2 Installing the CPU

Note in the above illustration that the CPU has a gold triangular mark on one corner. This mark indicates the processor Pin 1 that should match a specific corner of the CPU socket.

If installing only one CPU, use CPU socket 1 to ensure system stability..

Socket for CPU2

Socket for CPU1

Chapter 2: Hardware information

Incorrect installation of the CPU into the socket may bend the pins and severely damage the CPU!

Follow these steps to install a CPU.

1. Locate the 604-pin ZIF sockets on the motherboard. Flip up the socket lever and push it all the way to the other side.

Make sure that the socket lever is pushed back all the way, otherwise the CPU does not fit in completely.

Marked Corner

2. Position the CPU above the socket as shown.

3. Carefully insert the CPU into the socket until it fits in place.

The CPU fits only in one correct orientation. DO NOT force the CPU into the socket to prevent bending the pins and damaging the CPU!

4. Carefully push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked.

5. Apply the thermal interface material (thermal grease) to the top of the CPU. This thermal grease should come with the CPU package.

2.3.3 Installing the CPU heatsink and fan

The Intel® Xeon™ processors require an Intel certified heatsink and fan assembly to ensure optimum thermal condition and performance.

When you buy a boxed Intel CPU, the package includes the heatsink, fan, retention brackets, screws, thermal grease, installation manual, and other items that are necessary for CPU installation.

1. Perform the installation steps 1 to 3 in this section before

installing you motherboard into the chassis.

2. Make sure that you have applied the thermal grease to the top of the CPU before installing the heatsink and fan.

3. Refer to the installation manual that came with the CPU package for details on heatsink/fan assembly and installation.

To install the CPU heatsink and fan:

1. With the motherboard on a flat stable surface (such as a table), place the thermal plate underneath a CPU socket, matching the standoffs on the plate with the four holes around the CPU socket.

The figure below shows the corresponding matches of the motherboard holes and standoffs.

2. Place the heatsink retention mechanism over the CPU socket, matching its holes with the four holes on the motherboard and the standoffs on the thermal plate.

Heatsink retention mechanism

3. Secure the retention mechanism with the thermal plate using four screws.

4. Position the heatsink on top of the CPU, having its angled side (with cut corners) facing the memory sockets. Make sure that the heatsink base fits completely on the retention mechanism.

5. Secure the heatsink with the retention clips.

Retention clip

a. Insert the center hole of a

retention clip into the center tab on the retention mechanism.

b. Slightly move the clip to the right

so that the center tab is positioned on the narrow side of the hole. This ensures that the side holes fit on the side tabs.

c. Press one end of the clip to snap

its hole on the right side tab.

d. Press the other end of the clip to

snap its hole on the left side tab. This secures one side of the heatsink.

6. Follow step 5 to install the other retention clip, and completely secure the heatsink.
