Static Electricity Precautions

Static electricity could damage components on this motherboard.
T ake the following precautions while unpacking this motherboard
and installing it in a system.

1. Don’t take this motherboard and components out of their
original static-proof package until you are ready to install
them.

2. While installing, please wear a grounded wrist strap if
possible. If you don’t have a wrist strap, discharge static
electricity by touching the bare metal of the system chassis.

3. Carefully hold this motherboard by its edges. Do not touch
those components unless it is absolutely necessary. Put this
motherboard on the top of static-protection package with
component side facing up while installing.

Pre-Installation Inspection

1. Inspect this motherboard whether there are any damages to
components and connectors on the board.

2. If you suspect this motherboard has been damaged, do not
connect power to the system. Contact your motherboard
vendor about those damages.

Chapter 2: Motherboard Installation

Installing the Processor

This motherboard has a Socket 478 processor socket. When
choosing a processor, consider the performance requirements of
the system. Performance is based on the processor design, the
clock speed and system bus frequency of the processor, and the
quantity of internal cache memory and external cache memory .

CPU Installation Procedure

Follow these instructions to install the CPU:

Socket-478

CPUFAN

pin1

1. Unhook the locking lever of the CPU socket. Pull
the locking lever away from the socket and raising
it to the upright position.

2. Match the pin1 corner marked as the beveled edge
on the CPU with the pin1 corner on the socket.
Insert the CPU into the socket. Do not use force.

3. Push the locking lever down and hook it under the
latch on the edge of socket.

4. Apply thermal grease to the top of the CPU.

5. Install the cooling fan/heatsink unit onto the CPU,
and secure them all onto the socket base.

6. Plug the CPU fan power cable into the CPU fan
connector (CPUFAN) on the motherboard.

Installing Memor y Modules

This motherboard accommodates two 184-pin 2.5V unbuffered

Double Data Rate SDRAM (DDR SDRAM) Dual Inline

Memory Module (DIMM) sockets, and supports up to 2.0 GB
of 333(845GV)/266/200 MHz DDR SDRAM.

DDR SDRAM is a type of SDRAM that supports data transfers
on both edges of each clock cycle (the rising and falling edges),
effectively doubling the memory chip’s data throughput.

Chapter 2: Motherboard Installation

Memory Module Installation Procedure

These modules can be installed with up to 2 GB system memory .
Refer to the following to install the memory module.

1. Push down the latches on both sides of the DIMM
socket.

2. Align the memory module with the socket. There is a
notch on the DIMM socket that you can install the
DIMM module in the correct direction. Match the cutout
on the DIMM module with the notch on the DIMM
socket.

3. Install the DIMM module into the socket and press it
firmly down until it is seated correctly . The socket latches
are levered upwards and latch on to the edges of the
DIMM.

4. Install any remaining DIMM modules.

Jumper Settings

Connecting two pins with a jumper cap is SHORT; removing a
jumper cap from these pins, OPEN.

JP2: Clear CMOS Jumper

Use this jumper to clear the contents of the CMOS memory. You
may need to clear the CMOS memory if the settings in the Setup
Utility are incorrect and prevent your motherboard from operating.
To clear the CMOS memory, disconnect all the power cables from
the motherboard and then move the jumper cap into the CLEAR
setting for a few seconds.
