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.

Central Processing Unit: CPU

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.

CPU Installation Procedures

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

WARNING!

The mainboard supports AMD® Athlon/Athlon XP/Duron processor.
The mainboard uses a CPU socket called Socket-462 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.

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 recommends the use of high performance thermal inter­face material.

AMD Athlon 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.

You can check AMDs web site for more information on proper cooling.

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

While replacing the CPU, always turn off the ATX
power supply or unplug the power cable of the ATX
power supply from grounded outlet first to ensure the
safety of CPU.

WARNING!

Chapter 2

The mainboard provides 3 slots for 184-pin, 2.5V unbuffered DDR DIMM.
You can install PC1600/PC2100/PC2700 DDR SDRAM modules on the DDR
DIMM slots (DDR 1~3). To operate properly, at least one DIMM module must
be installed.

Memory

Introduction to DDR SDRAM

DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but
doubles the rate by transferring data twice per cycle. It uses 2.5 volts as op­posed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM modules
rather than 168-pin DIMM modules used by SDR SDRAM. High memory band­width makes DDR an ideal solution for high performance PC, workstations and
servers.

DDR DIMM Slots
(DDR 1~3)

Hardware Setup

2-5

DDR Module Combination

You can install either single-sided or double-sided 184-pin DDR DIMM
modules into DDR DIMM slots to meet your needs. Different from the SDR
DIMM, the DDR DIMM has only one notch on the center of module. The
number of pins on either side of the breaks are different. The module will only
fit in the right orientation.

You can install memory modules in any combination as follows:

Installing DDR Modules

1. The DDR DIMM has only one notch on the center of module. The module

will only fit in the right orientation.

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.

ATX 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 plugs 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. The power connector supports instant
power on function which means that system will boot up immediately when the
power supply connector is inserted on the board.

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.

problem, leave the setting at Disabled for optimal system stability and
performance. But if you are plagued by EMI, setting to Enabled for EMI
reduction. Remember to disable Spread Spectrum if you are overclocking be
cause even a slight jitter can introduce a temporary boost in clockspeed which

may just cause your overclocked processor to lock up.

Load High Performance/BIOS Setup Defaults

The two options on the main menu allow users to restore all of the BIOS
settings to High Performance defaults or BIOS Setup defaults. The High Per­formance Defaults are the default values set by the mainboard manufacturer
for the best system performance but probably will cause a stability issue. The
BIOS Setup Defaults are the default values also set by the mainboard manufac­turer for stable performance of the mainboard.

When you select Load High Performance Defaults, a message as below appears:

Pressing Y loads the default BIOS values that enable the best system
performance but may lead to a stability issue.

The option is for power or overclocking users only. Use of high
performance defaults will tighten most timings to increase the sys­tem performance. Therefore, a high-end system configuration is a
must, which means you need high-quality VGA adapter, RAM and
so on. We dont recommend that users should apply the high
performance defaults in their regular systems. Otherwise, the sys­tem may become unstable or even crash. If the system crashes or
hangs after enabling the feature, please CLEAR CMOS DATA to
resolve the problem. For more information, refer to Clear CMOS
Jumper:JBAT1 in Chapter 2.
