1.3 Special 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 SA TA 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.

1.3.2 ASUS unique features
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.

ASUS PSCH-SR 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.
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.

2.2 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 to 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
Secure the motherboard to the chassis with nine (9) screws on the holes
indicated by the circles.
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 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
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 Lever
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.

2.3.3 Installing 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.

2.4 System 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.
