Hardware Setup

This chapter provides you with the information about hardware setup
procedures. While doing the installation, be careful in holding the compo­nents and follow the installation procedures. For some components, if you
install in the wrong orientation, the components will not work properly.

Use a grounded wrist strap before handling computer components.
Static electricity may damage the components.

This chapter contains the following topics:

Chapter 2

Central Processing Unit: CPU

The mainboard supports Intel® Pentium® 4 processor. The mainboard
uses a CPU socket called Socket 478 for easy CPU installation. Make sure
that the CPU has a Heat Sink and a cooling fan attached to prevent
overheating. If you do not find the Heat Sink and cooling fan, contact your
dealer or purchase them before turning on the computer.

Installing the CPU

1. Pull the lever sideways away

from the socket. Then, raise
the lever up to a 90-degree
angle.

2. Look for the dot/cut edge.

The dot/cut edge should
point towards the lever
pivot. The CPU will only fit
in the correct orientation.

3. Hold the CPU down firmly,

and then close the lever to
complete the installation.

WARNING!

Overheating will seriously damage the CPU
and system, always make sure the cooling fan can work
properly to protect the CPU from overheating.

Hardware Setup

Installing the CPU Fan

As processor technology pushes to faster speeds and higher
performance, thermal management becomes increasingly important. To
dissipate heat, you need to attach the CPU cooling fan and heatsink on top
of the CPU. Follow the instructions below to install the Heatsink/Fan:

1. Locate the CPU and its retention

mechanism on the motherboard.

Retention Mechanism

3. Mount the fan on top of the

heatsink. Press down the fan until
its four clips get locked in the holes
of the retention mechanism.

2. Position the heatsink onto the

retention mechanism.

4. Press the two levers down to

fasten the fan. Each lever can be
pressed down in only ONE
direction.

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 1 4
then CPU core speed = Host Clock x Core/Bus ratio

= 100MHz x 14
= 1.4GHz

WARNING!

Overclocking

This motherboard is designed to support overclocking.
However, please make sure your components are able to
tolerate such abnormal setting, while doing overclocking.
Any attempt to operate beyond product specifications is
not recommended. We do not guarantee the damages or

risks caused by inadequate operation or beyond product
specifications.

Hardware Setup

Memory

The mainboard provides 2 sockets for 168-pin SDRAM DIMM (Double
In-Line Memory Module) modules and supports a maximum memory size of
2GB.

(DIMM 1~2)

Introduction to SDRAM

Synchronous DRAM (SDRAM) is a type of dynamic RAM memory
chip that has been widely used starting in the latter part of the 1990s. SDRAMs
are based on standard dynamic RAM chips, but have sophisticated features
that make them considerably faster. First, SDRAM chips are fast enough to be
synchronized with the CPU's clock, which eliminates wait states. Second, the
SDRAM chip is divided into two cell blocks, and data is interleaved between
the two so that while a bit in one block is being accessed, the bit in the other is
being prepared for access. This allows SDRAM to burst the second and
subsequent, contiguous characters at a rate of 10ns, compared to 60ns for the
first character.

SDRAM provides 800 MBps or 1 GBps data transfer depending on
whether the bus is 100MHz or 133MHz.

DIMM Modules Combination

You can install memory modules in any combination as follows:

DIMM 1 DIMM 2

S/D --

S (Single Side): 32MB ~ 512MB
D (Double Side): 64MB ~ 1GB

-- S/D

Note: As 845 chipset does not properly support the PC100 memory, it
is strongly recommended to install PC133 DIMM modules for better
system performance and stability. We do not guarantee the system
stability when installing PC 100 DIMM modules.

Installing DIMM Modules

1. The DIMM slot has 2 Notch Keys “VOLT and DRAM”, so the DIMM

memory module can only fit in one direction.

Front View Rear View

2. Insert the DIMM memory module vertically into the DIMM slot. Then

push it in.

3. The plastic clip at each side of the DIMM slot will automatically

close.

Hardware Setup

Power Supply

The mainboard supports ATX power supply for the power system.
Before inserting the power supply connectors, always make sure that all com­ponents are installed properly to ensure that no damage will be caused.

ATX 20-Pin Power Connector

This connector allows you to connect to an ATX power supply. To
connect to the ATX power supply, make sure the plug of the power supply is
inserted in the proper orientation and the pins are aligned. Then push down
the power supply firmly into the connector.
