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.

The VIA P4MA PRO mainboard supports the Intel®Pentium®4 Willamette/
Northwood and Celeron®processors in the 478 pin package (PGA478). When
installing the CPU, ensure the CPU has a large-size heatsink and a cooling
fanattachedon thetopto preventoverheating. If the heatsinkand cooling fan
are not included with the CPU, contact your dealer to purchase and install them
before turning on the computer.
CPU 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.
WARNING!
1. Pull the lever sideways away
fromthe socket. Then raisethe
lever up to a 90-degree angle.
2. Look for the dot/cut edge. The
dot/cut edge should point to-
wards the lever pivot. The
CPU will only fit in the correct
orientation.
3. Hold the CPU down firmly,
then close the lever shut to
complete the installation.

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:
CPU Core Speed
If CPUClock = 100MHz
Core/Bus ratio = 18
then CPU core speed = CPU Clock x Core/Bus ratio
= 100MHz x 18
= 1.8GHz
2. Position the heatsink and fan onto the
retention mechanism.
1. Locate the CPU and its retention
mechanism on the mainboard.
Retention mechanism
Overclocking
This mainboard is designed to support overclocking. However,
please make sure your components are able to tolerate such abnor-
mal 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 be-
WARNING!

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

The VIA P4MA PRO 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. Conven-
tional SDRAM only uses the rising edge of the clock to transfer data. Therefore,
conventionalSDRAMiscalledSDR(SingleDataRate)SDRAM.DDRSDRAM
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 mod-
ules 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:
Slot Memory Module TotalMemory
Slot 1
(Bank 0 & Bank 1) 64MB, 128MB, 256MB, 512MB, 1GB 64MB~1GB
Slot 2
(Bank 2 & Bank 3) 64MB, 128MB, 256MB, 512MB, 1GB 64MB~1GB
Maximum System Memory Supported 64MB~2GB
1. The DDR DIMM module has only one notch on the center.
2. Insert the DDR module vertically into the DDR DIMM slot. Make sure the
notch is correctly aligned.
3. The plastic clips at sides of the DIMM slot will automatically close shut.

Power Supply
The VIA P4MA PRO 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.
ATX 12V Power Connector: ATX12V
This 12V power connector is used to provide power to the CPU.
