Chapter 2. 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

The mainboard supports Intel® Pentium® 4 processor in the 478 pin
package. The mainboard uses a CPU socket called PGA478 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.

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.

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!

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 14

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

= 100MHz x 14
= 1.4GHz

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.

WARNING!

Chapter 2

2-4

The mainboard provides 2 slots for 168-pin, 3.3V SDRAM DIMM with 4
memory banks. You can install PC133/PC100 SDRAM modules on the DIMM
slots (DIMM 1~2). Advice: DDR Modules have only one notch!

Memory (This section describes only S-DRAM

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.

Hardware Setup

2-5

T o operate properly, at least one DIMM module must be installed. Memory
modules can be installed on the slots in any order. You can install either single­or double-sided 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 & Bank 1)

S/D 32MB~1GB

DIMM 2
(Bank 2 & Bank 3)

S/D 32MB~1GB

32MB~2GB

DIMM Module Combination

S: Single Side D: Double Side

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

it in.

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

Installing DIMM Modules

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

Power Supply

A TX 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.

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.

Slots

AGP (Accelerated Graphics Port) Slot

The AGP slot allows you to insert the AGP graphics card. AGP is an
interface specification designed for the throughput demands of 3D graphics.
It introduces a 66MHz, 32-bit channel for the graphics controller to directly
access main memory and provides three levels of throughputs: 1x (266Mbps),
2x (533Mbps) and 4x (1.07Gbps).

PCI Slots

Three PCI slots allow you to insert the expansion cards to meet your
needs. When adding or removing expansion cards, make sure that you unplug
the power supply first. Meanwhile, read the documentation for the expansion
card to make any necessary hardware or software settings for the expansion
card, such as jumpers, switches or BIOS configuration.

The motherboard provides three 32-bit Master PCI bus slots and one
AGPslot.

PCI Interrupt Request Routing

The IRQ, abbreviation of interrupt request line and pronounced I-R-Q,
are hardware lines over which devices can send interrupt signals to the
microprocessor. The PCI IRQ pins are typically connected to the PCI bus INT
A# ~ INT D# pins as follows:

Order 1 Order 2 Order 3 Order 4
PCI Slot 1 INT A# INT B# INT C# INT D#
PCI Slot 2 INT B# INT C# INT D# INT A#

The mainboard is able to active the audio connectors from 2-channel to 4-/6­channel or the SPDIF connectors. To use the function, you need to install the
C-Media drivers.

T o install C-Media drivers:

1. Insert the companion CD into the CD-ROM drive. The setup screen will

automatically appear.

2. Click on C-Media Sound Drivers.

3. Follow the on-screen instructions to complete installation.

4. Restart the system.
