®
d
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

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 12 inches x 9 inches (30.5 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 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.

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 3.2GB/s. The socket will
also support the Intel Prescott CPU when available. (*Overclocking mode)
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.

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.
7. Double-sided DDR DIMMs with x16 (databus width = 16-bit) memory chips
are not supported due to chipset limitation.
8. It is recommended to use the blue DIMM slots first.
