Installation

Installation

This chapter provides you with information
about hardware setup procedures. While installing
the mainboard, carefully hold the components and
closely follow the installation procedures. Some
components may be damaged if they are installed
incorrectly.

It is recommended to use a grounded wrist
strap before handling computer components. Static
electricity can damage some components.

Chapter 2

CPU Installation

The VIA P4MA mainboard supports the Intel® Pentium® 4 processor in the 478
pin package (PGA478). When installing the CPU, ensure the CPU has a large-
size heatsink and a cooling fan attached on the top to prevent overheating. If
the heatsink and cooling fan are not included with the CPU, contact your
dealer to purchase and install them before turning on the computer.

CPU Installation

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.

WARNING!

3. Hold the CPU down firmly,
then close the lever shut to
complete the installation.

Overheating will cause serious damage to the CPU
and system. Ensure the cooling fan and heatsink work
properly to protect the CPU from overheating.

2-2

Installation

CPU Core Speed

If CPU Clock = 100MHz

Core/Bus ratio = 18

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

= 100MHz x 18
= 1.8GHz

Overclocking

This mainboard is designed to support overclocking. However,

WARNING!

please make sure your components are able to tolerate such abnor­mal settings, before overclocking. Any attempt to operate beyond
product specifications is not recommended. We do not guarantee the
damages or risks caused by inadequate operation or operation beyond

CPU Fan Installation

As processor technology pushes to faster speeds and higher performance,
thermal management becomes increasingly important. To dissipate heat, you
MUST 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 mainboard.

Retention mechanism

2. Position the heatsink and fan onto the
retention mechanism.

2-3

Chapter 2

3. Mount the fan on top of the heatsink. Press down the fan firmly until its four clips
become wedged in the holes of the retention mechanism.

4. Press the two levers down to secure the fan. Each lever can be pressed down in only
ONE direction.

5. Connect the fan power cable from the mounted fan to the 3-pin fan power connector
on the mainboard.

2-4

Installation

Memory Installation

The VIA P4MA mainboard provides 2 sockets for 184-pin, 2.5V DDR DIMM
modules with 4 memory banks. To operate properly, at least one DIMM module
must be installed.
You can install PC1600/PC2100 DDR SDRAM modules on the DDR DIMM
slots (DDR 1~2).
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but
doubles the rate of transfer by transfering data twice per cycle. This is achieved
by transfering data on both the rising and falling edges of the clock.
Conventional SDRAM only uses the rising edge of the clock to transfer data.
Therefore, conventional SDRAM is called SDR (Single Data Rate) SDRAM.
DDR SDRAM 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. DDR SDRAM is also known as SDRAM-II, DDR DRAM and
DSDRAM (Double-Speed DRAM). PC2100 running at 133MHz will produce

2.1GB/s memory bandwidth. High memory bandwidth makes DDR an ideal
solution for high performance PC, workstations and servers.

DDR Module Installation

You can install either single sided or double sided 184-pin DDR DIMM modules
into the DDR DIMM slot, depending on your requirements. Differing from
SDR DIMM, DDR DIMM modules have only one notch on the center of the
module. The number of pins on either side of the breaks are also different. The
memory modules will only fit if placed in the correct orientation.
You can install DDR SDRAM modules in any of the following combinations:

2. Insert the DDR module vertically into the DDR DIMM slot. Make sure the

3. The plastic clips at sides of the DIMM slot will automatically close shut.

Installation

Power Supply

The VIA P4MA mainboard requires an ATX power supply for powering the
system. Before inserting the power supply connector, always make sure that all
components are installed properly to ensure that no damage will be caused.

ATX 20-Pin Power Connector: ATXPWR

This connector is for the ATX power supply. To connect to the ATX power
supply, make sure the plugs of the power supply are inserted in the correct
orientation and the pins are properly aligned. Then, push down the plugs
firmly into the connector.
