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
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

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
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,
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 CPU Clock = 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 abnor­mal settings, before overclocking. Any attempt to operate beyond
product specifications is not recommended. W e do not guarantee the
damages or risks caused by inadequate operation or operation be-

W ARNING!

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.

Installation

2-5

The VIA P4MA PRO mainboard provides 2 sockets for 184-pin, 2.5V DDR
DIMM modules with 4 memory banks. T o 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 184­pin 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:

Clear CMOS Jumper: CLEAR_CMOS

The onboard CMOS RAM stores system configuration data and has an onboard
battery power supply. The long-life battery has a lifetime of at least 5 years. If
you want to clear the system configuration data from the CMOS RAM, use the
CLEAR_CMOS (Clear CMOS jumper). Follow the instructions below to clear
the data:

Jumpers

The VIA P4MA PRO mainboard provides jumpers for setting the mainboard’ s
functions. This section will explain how to change settings for your mainboard’ s
functions through the use of the jumpers.

You can clear the CMOS by shorting 1-2 pin while
the system is off. Then return it to the 2-3 pin
position. Avoid clearing the CMOS while the
system is on; this will damage the mainboard.

Slots

AGP (Accelerated Graphics Port) Slot

The AGP4X slot allows you to insert an 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 (266MB/s), 2x (533MB/
s) and 4x (1.07GB/s).

PCI Slots

The three PCI slots allow you to insert expansion cards to meet your needs.
When adding or removing PCI expansion cards, ensure 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.

CNR (Communication Network Riser) Slot

The CNR slot allows you to insert a CNR expansion card. CNR is a specially
designed network, audio, or modem riser card for ATX family mainboards. Its
main processing is done through software and is controlled by the mainboard’ s
chipset.

This setting allows you to adjust the CPU Vcore by increasing or decreasing

0.025 each time. Please note that it may be dangerous to adjust
the Vcore over 10% of original CPU specification

DRAM Voltage

This setting allows you to set the appropriate DRAM voltage. Setting
options: 2.5V, 2.6V, 2.7V and 2.8V.

CPU Clock

This setting specifies the clock frequency of CPU host bus (FSB) and
provides a method for end-users to overclock the processor accordingly.

If the CPU clock is set over the tolerance limit of the CPU, the mainboard will
show the following message “IMPROPER OVERCLOCKING SETTING, SYS­TEM IS RESETTING CPU CLOCK TO DEFAULT. Please re-enter BIOS Setup
and remember to save before quit!”. This feature protects the CPU from damage
due to overclocking.

CPU Clock Ratio

This setting controls the multiplier that is used to determine the internal clock
speed of the processor relative to the external or motherboard clock speed.

Spread Spectrum

When the motherboard’s clock generator pulses, the extreme values (spikes) of
the pulses creates EMI (Electromagnetic Interference). The Spread Spectrum
function reduces the EMI generated by modulating the pulses so that the spikes
of the pulses are reduced to flatter curves. If you do not have any EMI problems,
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 because even a 0.25% jitter can
introduce a temporary boost in clockspeed of 25MHz (with a 1GHz CPU) which
may just cause your overclocked processor to lock up. Settings: Disabled, -1.

Set Supervisor/User Password

When you select this function, a message as below will appear on the screen:

Type the password, up to eight characters in length, and press <Enter>.
The password typed now will clear any previously set password from
CMOS memory. You will be prompted to confirm the password. Re-type
the password and press <Enter>. You may also press <Esc> to abort the
selection and not enter a password.

To clear a set password, just press <Enter> when you are prompted to
enter the password. A message will show up confirming that the pass­word will be disabled. Once the password is disabled, the system will
boot and you can enter Setup without entering any password.

When a password has been set, you will be prompted to enter it every
time you try to enter Setup. This prevents an unauthorized person from
changing any part of your system configuration.

Additionally, when a password is enabled, you can also have BIOS to
request a password each time the system is booted. This would prevent
unauthorized use of your computer. The setting to determine when the
password prompt is required is the Security Option of the Advanced
BIOS Features menu. If the Security Option is set to System, the password
is required both at boot and at entry to Setup. If set to Setup, password
prompt only occurs when trying to enter Setup.
