1.3Special features

1.3.1 Product highlights

Latest processor technology

The motherboard supports the latest Intel® Pentium™ 4 processor via a 478-pin surface mount ZIF socket. The processor with 1 MB/512 KB L2 cache includes a 800/533/400 MHz system bus and features the Intel Hyper-Threading Technology and new power design that allow up to 3.4+ GHz core frequencies. The motherboard fully supports the new generation 90 nm Pentium® 4 processor.

Dual-channel DDR400 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 4 GB of system memory using PC3200/2700/2100 ECC or non-ECC DDR DIMMs to deliver up to 6.4 GB/s data transfer rate for various server applications.

Serial ATA technology

The motherboard supports the new Serial ATA technology through the SATA interfaces and the Intel® 6300ESB. The SATA specification allows for thinner, more flexible cables with lower pin count, reduced voltage requirement, and up to 150 MB/s data transfer rate. For Serial ATA models, the Adaptec® AIC-8110X chip supports four additional SATA connectors to give you six fully-compatible SATA interfaces. For IDE models, the Intel® 6300ESB ICH provides RAID 0 and RAID 1 solution for two Serial ATA interfaces using the Windows® XP operating system.

Zero Channel RAID (ZCR) solution (optional on SATA and SCSI models only)

The motherboard supports the optional Zero Channel RAID card in SODIMM package for a multi-RAID solution using Serial ATA150 hard disk drives or Ultra320 SCSI hard disk drives. The RAID 0 (striping), RAID 1 (mirroring), RAID 0+1, and RAID 5 provide a cost-effective, reliable and high-performance server system.

1-2	Chapter 1: Product introduction

Single-channel Ultra320 SCSI support (on SCSI models only)

The Adaptec® AIC-7901X Ultra320 SCSI controller and single-channel SCSI connector are onboard to provide high-speed data transfers to and from SCSI hard disk drives.

Integrated graphics

The onboard ATI Rage™ XL graphics controller with 8 MB memory provides a reliable solution for server applications.

USB 2.0 technology

The motherboard implements the Universal Serial Bus (USB) 2.0 specification, dramatically increasing the connection speed from the 12Mbps bandwidth on USB 1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is backward compatible with USB 1.1.

Dual Gigabit LAN solution

The Intel® 82541GI and Intel® 82547GI Gigabit Ethernet controller allows full-duplex Gigabit performance on LAN on Motherboard (LOM) applications. Take the advantage of the Communication Streaming Architecture (CSA) with the Intel® 82547GI controller that connects to the dedicated CSA bus on the Memory Controller Hub (MCH). This reduces the PCI bottlenecks by freeing the PCI bus for other I/O operations. The Intel® 82541GI controller utilizes the PCI interface on the Southbridge to provide a faster and more efficient networking performance.

Server management

With the onboard Baseboard Management Connector (BMC) for the ASUS server management card, managing your server motherboard has never been this easy. ASUS server management cards fully conform to the IPMI1.5 or 2.0 versions.

Chassis intrusion detection

The motherboard supports chassis intrusion monitoring through the Winbond ASIC. A chassis intrusion event is retained in the CMOS for added protection.

2.1Before 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.

Power LED

The motherboard has a green power LED (SB_PWR1). When lit, this LED 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.

2.3Central Processing Unit (CPU)

2.3.1 Overview

The motherboard comes with a surface mount 478-pin Zero Insertion Force (ZIF) socket. The socket is designed for the Intel® Pentium™ 4 processor in the 478-pin package with 1 MB/512 KB L2 cache.

Take note of the marked corner (with gold		Gold Mark
triangle) on the CPU. This mark should match
a specific corner of the CPU socket.

2.3.2 Installing the CPU

Follow these steps to install a CPU.

1. Locate the 478-pin ZIF socket on the motherboard.

2.Unlock the socket by pressing the lever sideways, then lift it up to a 90°-100° angle.

Socket

Make sure that the socket lever is lifted up to 90°-100° angle; otherwise, the CPU does not fit in completely.

3.Position the CPU above the socket such that its marked corner matches the base of the socket lever.

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

90º ~ 100º angle

Gold Mark

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!

5.When the CPU is in place, push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked.

After installation, make sure to plug-in the 4-pin ATX power cable to the motherboard.

2.3.3Installing the optional CPU heatsink and thermal plate

The passive CPU heatsink and a thermal plate is purchased separately. For optimum thermal solution, use the recommended CPU heatsink and thermal plate.

CPU thermal plate

This motherboard requires a thermal plate for the CPU. Place the thermal plate underneath the motherboard before you install the heatsink.

Refer to the picture below for the correct matching of the motherboard and thermal plate holes.

To install the CPU heatsink:

1.Carefully place the heatsink on top of the installed CPU.

2.Hold down the heatsink lightly and twist each of the four screws with a Philips (cross) screwdriver just enough to attach the heatsink to the motherboard.

3.When the four screws are attached, tighten them one by one to completely secure the heatsink.

Do not overtighten the screws to avoid damaging the motherboard.

2.4System memory

2.4.1 Overview

The motherboard comes with four Double Data Rate (DDR) Dual Inline Memory Module (DIMM) sockets.

The following figure illustrates the location of the sockets.

2.4.2 Memory configurations

You may install 64 MB, 128 MB, 256 MB, 512 MB, and 1GB DDR DIMMs into the DIMM sockets using the memory configurations in this section.

Important notes on memory configurations

• Installing DDR DIMMs other than the recommended configurations may cause memory sizing error or system boot failure. Use any of the recommended configurations in Table 1.

•Use the blue DIMM slots first.

•In Dual-channel configurations, install only identical (the same type and size) DDR DIMM pairs for each channel.

•Always install DIMMs with the same CAS latency, otherwise, the system may run in a lower frequency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor.

•When all four sockets are populated with 1 GB DIMMs (total 4 GB), the system may detect only 3583 MB due to the Southbridge resource allocation.

•Three DDR DIMMs installed into any three memory sockets will function in single channel mode.

•Make sure that the memory frequency matches the CPU FSB. Refer to Table 2 for configurations.

*For dual-channel configuration (3), you may:

•install identical DIMMs in all four sockets or

•install identical DIMM pair in DIMM_A1 and DIMM_B1 (blue sockets) and identical DIMM pair in DIMM_A2 and DIMM_B2 (black sockets)

Table 2: Memory frequency/CPU FSB synchronization

CPU FSB	DDR DIMM Type	Memory Frequency

533 MHz	PC2700/PC2100	333/266 MHz
400 MHz	PC2100	266 MHz

*When using 800MHz CPU FSB, PC2700 DDR DIMMs may run only at 320MHz (not 333MHz) due to the Southbridge resource allocation.
