1.6 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 standby power 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.

1.7 Motherboard installation
Before you install the motherboard, study the configuration of your chassis to
ensure that the motherboard fits into it. The motherboard uses the micro-ATX form
factor that measures 9.6 inches x 9.6 inches (24.5 cm x 24.5 cm).
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.
1.7.1 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.
1.7.2 Screw holes
Place eight (8) 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

1.8 Central Processing Unit (CPU)
1.8.1 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 512KB L2 cache. This processor supports 800/533/400MHz front
side bus (FSB), and allows data transfer rates of up to 6.4GB/s. The socket will
also support the Intel Prescott CPU when available.
Note in the 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.
Incorrect installation of the CPU into the socket may bend the pins and
severely damage the CPU!
Notes on Intel® Hyper-Threading Technology
1. This motherboard supports Intel Pentium 4 CPUs with Hyper-Threading
Technology .
2. Hyper-Threading Technology is supported under Windows XP and later
versions only . If you are using any other operating systems, disable the
Hyper-Threading Techonology item in BIOS to ensure system stability and
performance.
Gold Mark
3. It is recommended that you install WinXP Service Pack 1.
4. Make sure to enable the Hyper-Threading Technology item in BIOS before
installing a supported operating system.
5. For more information on Hyper-Threading Technology , visit www.intel.com/
info/hyperthreading.
To use the Hyper-Threading Technology on this motherboard:
1. Buy an Intel Pentium 4 CPU that supports Hyper-Threading Technology. Install
the CPU.
2. Power up the system and enter BIOS Setup. Under the Advanced Menu, make
sure that the item Hyper-Threading Technology is set to Enabled. The item
appears only if you installed a CPU that supports Hyper-Threading Technology.
See Chapter 2 for BIOS Setup information.
3. Reboot the computer.

1.8.2 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.
90 -100
Gold Mark
4. 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!
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.
6. Install a CPU heatsink and fan
following the instructions that came
with the heatsink package.
7. Connect the CPU fan cable to the
CPU_FAN1 connector on the
motherboard.

1.9 System memory
The motherboard comes with four Double Data Rate (DDR) Dual Inline Memory
Module (DIMM) sockets. These sockets support up to 4GB system memory using
184-pin unbuffered non-ECC PC3200/PC2700/PC2100 DDR DIMMs. The
following figure shows the location of the DDR DIMM sockets.

1.9.1 Memory configurations
You may install 64MB, 128MB, 256MB, 512MB, and 1GB DDR DIMMs into the
DIMM sockets using the memory configurations in this section.
Important notes
1. 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.
2. In dual-channel configurations, install only identical (the same type and
size) DDR DIMM pairs for each channel.
3. Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from the
same vendor.
4. Make sure that the memory frequency matches the CPU FSB (Front Side
Bus). Refer to Table 2.
5. DIMMs installed into any three sockets will function in single-channel
mode.
6. When all four sockets are populated with 1GB DIMMs (total 4GB), the
system may detect only 3+GB (a little less than 4GB) due to ICH5 resource
allocation.

Table 2 Memory frequency/CPU FSB synchronization
This motherboard supports different memory frequencies depending on the CPU
FSB (Front Side Bus) and the type of DDR DIMM.
CPU FSB DDR DIMM Type Memory Frequency
800 MHz PC3200/PC2700*/PC2100 400/333*/266 MHz
1-14
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 chipset limitation.
