AMD Athlon™ XP/ Athlon™/ Duron™ Processor Family

Cooling Solutions

As processor technology pushes to faster speed and higher performance, thermal management
becomes increasingly crucial when building computer systems. Maintaining the proper thermal
environment is key to reliable, long-term system operation. The overall goal in providing the proper
thermal environment is keeping the processor below its specified maximum case temperature.
Heatsinks induce improved processor heat dissipation through increased surface area and concentrated
airflow from attached fans. In addition, interface materials allow effective transfers of heat from the
processor to the heatsink. For optimum heat transfer, AMD recommends the use of thermal grease and
mounting clips to attach the heatsink to the processor.

When selecting a thermal solution for your system, please refer to the website below for collection of
heatsinks evaluated and recommended by AMD for use with AMD processors. Note, those heatsinks
are recommended for maintaining the specified maximum Tcase requirement. In addition, this
collection is not intended to be a comprehensive listing of all heatsinks that support AMD processors.

Chapter 1

Introduction of N2PA-LITE/N2PAP-LITE Motherboard

1-1 Features of Motherboard

The all new N2PA-LITE and N2PAP-LITE is the latest desktop motherboard solution
incorporating support for the new AMD Athlon™ XP processor 3200+ with advanced

400MHz front side bus technology (FSB) and DDR400 memory modules. It brings the power
and performance of NVIDIA nForce2 technology to the mainstream market with more
features and functionality.

Designed with the latest NVIDIA nForce2 400 platform processors, the motherboard supports

400MHz system bus with DDR400 memory interface, a single 64-bit architecture, delivering
unparalleled performance and features to the mainstream. The AGP 8X graphic interface
support enables enhanced graphics performance with high bandwidth speed up to 2.12GB/s
and is twice as fast as AGP 4X. To complete the integrated digital media gateway
functionality, the motherboard also incorporates NVIDIA nForce2 MCP (Media and
Communication Processor) with capability exceeding the traditional Southbridge connectivity
to provide serial, parallel, Ultra DMA133, up to six USB 2.0 ports. Also integrated are special
features such as CPU overheating protection, overclocking, and lots more. Altogether, the
features on the motherboard support a broad range user experience for today’s computer
market.

A special onboard CPU overheating protection circuit preventing AMD processor from being
burned will automatically shutdown the power when CPU temperature is higher than the
preset value, or when the CPU FAN is not working. Also built-in is the hardware monitoring
function to monitor and protect your system.

The motherboard is designed to support DDR memory 2.5V voltage and AGP 1.5V voltage
which can be minor-adjusted in BIOS setup. This is intended to provide user with the
support of overclocking with more stable system

. Also supported are adjustable CPU host

clock in BIOS setup and hardware protection for BIOS against virus crash.

Note: CPU Front Side Bus Frequency also can be changed in BIOS SETUP. Please refer

to page 32 “Host Clock at Next Boot Is” selection in Miscellaneous Control menu.

Note: When the overclocking causes system boot failure, you will need to hold the “INS”

key and the power on button at the same time until the screen resumes display to the
standard default. Otherwise the CMOS will keep the faulty data and the
motherboard will not function.

(3) CMOS RAM Clear (3-pin) : JP3

A battery must be used to retain the motherboard configuration in CMOS RAM.
Shorting 1-2 pins of JP3 will store the CMOS data.

To clear the CMOS, follow the procedure in below:

1. Turn off the system and unplug the AC power

2. Remove ATX power cable from ATX power connector

3. Locate JP3 and short pins 2-3 for a few seconds

4. Return JP3 to its normal setting by shorting pins 1-2

5. Connect ATX power cable back to ATX power connector

Note: When should CMOS be cleared

1. Troubleshooting

2. Forget password

3. System boot failure after overclocking

2-3-2 About AMD Athlon XP, Athlon & Duron 462-pin CPU

This motherboard supports Socket-A (Socket-462) AMD Athlon/Duron processors.

This motherboard Provides a ZIF Socket-A. The CPU to be used with the motherboard
should have a cooling FAN attached to prevent overheating. If this is not the case, then
purchase a correct cooling FAN before you turn on your system.

WARNING!

Be sure that there is sufficient air circulation across the processor’s heatsink and
CPU cooling FAN is working correctly, otherwise it may cause the processor and
motherboard overheat and damage, you may install an auxiliary cooling FAN, if
necessary.

WARNING!

Due to this motherboard provides new function of protecting CPU；you must
connect the CPU FAN connector on CPUFAN location in order to obtain this
feature. Without connection on CPUFAN (or you have connect CPU FAN on
SFAN1), the system will shut down immediately to protect both your CPU and
motherboard.

Overheat Protect:

Only for Athlon XP series CPU, when the CPU is overheated, system will
automatically shut down power supply. You can hear a continue beep sound, the

9

power button will be locked up. You must turn off and turn on the AC power to
reset the system. Otherwise, the power button will not function. The other way is
to keep pressing the button for a few seconds till the beep sound stops. Then,
release the power button and press the power button again to turn on the power
supply.

To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket and
open it by first pulling the lever sideways away from the socket and lift the lever upward to a
90-degree angle. Insert the CPU with the correct orientation as shown below. The notched
corner should be pointed toward the end of the lever. The CPU has corner pin on two of the
four corners and the CPU will only fit in the orientation as shown.

CPU ZIF Socket-A

Colden Arrow

Socket 462

When you insert the CPU onto the ZIF socket, no force is required. After inserting, press the
lever slightly without any extra force to lock CPU in position.

2-4 Install Memory

This motherboard provides two 184-pin DUAL INLINE MEMORY MODULES (DIMM)
sockets for memory expansion from a minimum memory size of 64MB to maximum memory
size of 2.0GB DDR SDRAM.

Valid Memory Configurations

Bank 184-Pin DIMM PCS Total Memory

Bank 0, 1 (DIMM1) DDR 266/333/400 DDR SDRAM X1

64MB∼1.0GB

Bank 2, 3 (DIMM2) DDR 266/333/400 DDR SDRAM X1

64MB∼1.0GB

Total System Memory (Max. 2.0GB) 2

64MB∼2.0GB

NOTE!

Make sure the total installed memory size does not exceeds 2.0GB. Otherwise,
the system may hang during startup.

Generally, installing DDR SDRAM modules to the motherboard is very straightforward.
Please refer to figure 2-4 for the detail of 184-Pin

DDR 266/333/400

DDR SDRAM module

and the socket.

10

DI MM2 (BANK2 + BANK3)

DI MM1 (BANK0 + BANK1)

NOTE!

When you install DIMM module fully into the DIMM socket the eject tab
should be locked into the DIMM module very firmly and fit into its
indention on both sides.

WARNING!

For the DDR SDRAM CLOCK setting of 166MHz, use only DDR333 compliant
DDR Modules. When this motherboard operates at 133Mhz, most system will not
even boot if non-compliant modules are used because of the strict timing issues, if
your DDR Modules are not DDR266-compliant, set the DDR SDRAM clock to
100MHz to ensure system stability.

2-5 Expansion Cards

WARNING!

Turn off the power when adding or removing expansion cards or other system
components. Failing to do so may cause severe damage to both the motherboard
and expansion cards.

2-5-1 Procedure For Expansion Card Installation

1. Read the documentation of the expansion card and make any necessary hardware or
software setting on the expansion card, such as jumpers, before installing.

2. Remove computer cover and the bracket plate on the slot you intend to use.

3. Align the card’s connectors and press firmly.

4. Secure the card on the slot with the screw you remove above.

5. Replace the computer system’s cover.

6. Set up the BIOS if necessary.

7. Install the necessary software driver of expansion card.

2-5-2 Assigning IRQs For Expansion Card

Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclusively
assigned. In a standard design, there are 16 IRQs available, but most of them might already be
in use.

Figure 2-4
