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.

Chapter 2

Central Processing Unit: CPU

The mainboard supports AMD® Athlon™, Athlon™ XP and Duron™
processors in the 462 pin package. The mainboard uses a CPU socket called
Socket A for easy CPU installation. When you are installing the CPU, make

sure the CPU has a heat sink and a cooling fan attached on the top to prevent
overheating. If you do not find the heat sink and cooling fan, contact your

dealer to purchase and install them before turning on the computer.

CPU Installation Procedures

1. Pull the lever sideways away

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

2. Look for the cut edge. The

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.

WARNING! Thermal Issue for CPU

As processor technology pushes to faster speeds and higher performance,
thermal management becomes increasingly crucial when building computer
systems. Maintaining the proper thermal environment is key to reliable
operation. As such, the processor must be maintained in the specified thermal
requirements.

AMD Athlon™/Duron™/Athlon™ XP processor with a speed of 600MHz
and above requires LARGER heatsink and fan. You also need to add thermal
grease between the CPU and heatsink to improve heat dissipation. Then, make
sure that the CPU and heatsink are securely fastened and in good contact with
each other. These are needed to prevent damaging the processor and ensur­ing reliable operation. If you want to get more information on the proper
cooling, you can visit AMD’s website for reference.

Chapter 2

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 7

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

= 100MHz x 7
= 700MHz

CPU Clock Selection

T o make a 100MHz CPU run at 100MHz or a 133MHz CPU run at 133MHz,
you need to adjust the CPU clock frequency through the jumper JFSB1.

For more information on the issue, refer to CPU Clock Selection Jumper:
JFSB1 later in this chapter.

Overclocking

WARNING!

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 unbuffered SDRAM DIMM
(Double In-Line Memory Module) modules and supports the memory size up
to 1 GB. The socket supports 256MB technology.

DIMM Slots

(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.

Chapter 2

DIMM Module Combination

Install at least one DIMM module on the slots. Memory modules can be
installed on the slots in any order. You can install either single- or double­sided modules to meet your own needs.

Memory modules can be installed in any combination as follows:

Slot Memory Module Total Memory

DIMM 1
(Bank 0 & 1)
DIMM 2
(Bank 2 & 3)

Maximum System Memory Supported

S: Single Side D: Double Side

S/D 32MB~512MB

S/D 32MB~512MB

32MB~1GB

Installing DIMM Modules

The DIMM slot has 2 Notch Keys “VOL T and DRAM”. The module will
only fit in the right orientation.

1. Insert the DIMM memory module vertically into the DIMM slot. Then push

it in.

Hardware Setup

Power Supply

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

A TX 20-Pin Power Connector: JPWR1

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.
