AMD Athlon™ XP / Duron™ Processor Family

Cooling Solutions

As processor technology pushes to faster speeds 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 T case requirement. In addition, this
collection is not intended to be a comprehensive listing of all heatsinks that support AMD processors.

Frequency CPU, which utilize the Socket-A design and the memory size expandable to 3.0GB.

V400DB/V400DBL/V400ADB/V400ADBL motherboard use the newest VIA KT400/
KT400A chipset, whose 333/266MHz (Double Data Rate) Front Side Bus frequency delivers
a clear upgrade path to the future generation of 200/266/333MHz processors. The V400DB/
V400DBL/V400ADB/V400ADBL provided 266/333/400MHz memory frequency supported
DDR266/DDR333 DDR SDRAM. The V400DB/V400DBL/V400ADB/ V400ADBL
motherboard offers ULTRA ATA 133 to provide speedier HDD throughout that boosts overall
system performance.

These motherboards also has an integrated AC’97 CODEC on board which is fully compatible
with Sound Blaster Pro that gives you the best sound quality and compatibility. It Supports 6
channel Speaker for 3D Surround Effect.

For those wanting even greater graphic performance, an AGP 8X slot is included on the board.

The V400DBL/V400ADBL motherboard use VIA VT6103 LAN PHY support 10/100Mbps
data transfer rate full duplex, half duplex operation.

With USB control as well as capability of expanding to 6 USB function ports support
USB2.0/USB1.1 Devices, the V400DB/V400DBL/V400ADB/V400ADBL meet future USB
demand also this motherboard has built-in hardware monitor function. This will monitor and
protect your computer.

A special design in hardware for protecting Athlon XP CPU from burned, the system will auto
shutdown power supply when CPU is overheat or the CPU FAN is stop.

In V400DB/V400DBL/V400ADB/V400ADBL we design in DDR memory 2.5V Voltage,
AGP 1.5V Voltage those can minor adjustable in BIOS setup. This design can let users
approach over clock demand and also can make system more stable. The V400DB/

V400DBL/V400ADB/V400ADBL motherboard provides special function in BIOS Setup to
setting CPU Host clock step by step increasing let users to approach over clocking.

V400DB/V400DBL/V400ADB/V400ADBL provides high performance & meets future
specification demand. It is really wise choice for your computer.

establish the relationship between the various components.

Driver - software, which defines the characteristics of a device for use by another device or
other software.

Processor - the "central processing unit" (CPU); the principal integrated circuit used for doing
the "computing" in "personal computer"

Front Side Bus Frequency -

the working frequency of the motherboard, which is generated

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

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

This motherboard Provides a ZIF Socket-A. The CPU that comes 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
FAN1), the system will shut down immediately to protect both your CPU and
motherboard.

Over heat Protect:

Only for Athlon XP serial CPU, when the CPU overheat, system will auto
shut down power supply. You can hear a continue beep sound, the power
button will be locked up. Users must turn off and turn on the AC power
to reset the system otherwise the power button will no function, the other
way is keeping press the push button few seconds till the beep sound stop,
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 level sideways away from the socket then upward to a 90-degree
angle. Insert the CPU with the correct orientation as shown below. The notched corner
should point toward the end of the level. Because the CPU has a corner pin for two of the
four corners, the CPU will only fit in the orientation as shown.

CPU ZIF Socket-A

Colden Arrow

When you put the CPU into the ZIF socket. No force require to insert of the CPU, then press
the level to Locate position slightly without any extra force.

2-4 Install Memory

This motherboard provides three 184-pin DUAL INLINE MEMORY MODULES (DIMM)
sites for memory expansion available from minimum memory size of 64MB to maximum
memory size of 3.0GB DDR SDRAM.

Valid Memory Configurations

Bank 184-Pin DIMM PCS Total Memory

Bank 0, 1 (DDR1) PC2100/PC2700 DDR SDRAM X1 64MB∼1.0GB
Bank 2, 3 (DDR2) PC2100/PC2700 DDR SDRAM X1 64MB∼1.0GB
Bank 4, 5 (DDR3) PC2100/PC2700 DDR SDRAM X1 64MB∼1.0GB

Total System Memory (Max. 3.0GB) 3 64MB∼3.0GB

NOTE!

Make sure the total installed memory does not exceeds 3.0GB, otherwise the
system may hang during startup.

Generally, installing DDR SDRAM modules to your motherboard is very easy, you can refer
to figure 2-4 to see what a 184-Pin PC2100/PC2700 DDR SDRAM module looks like.

DDR2 (BANK2 + BANK3)

DDR1 (BANK0 + BANK1)

DDR3 (BANK4 + BANK5)

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 is set at 166MHz, use only PC2700­compliant DDR Modules. When this motherboard operate 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 PC2100-compliant, set the
DDR SDRAM clock to 100MHz to ensure system stability.

2-5 Expansion Cards

WARNING!

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

2-5-1 Procedure For Expansion Card Installation

1. Read the documentation for your expansion card and make any necessary hardware or
software setting for your expansion card such as jumpers.

2. Remove your computer’s 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 screen you remove above.

5. Replace the computer system’s cover.

6. Set up the BIOS if necessary.

7. Install the necessary software driver for your expansion card.

2-5-2 Assigning IRQs For Expansion Card

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

Standard Interrupt Assignments

IRQ Priority Standard function

0 N/A System Timer
1 N/A Keyboard Controller
2 N/A Programmable Interrupt
3 * 8 Communications Port (COM2)
4 * 9 Communications Port (COM1)
5 * 6 Sound Card (sometimes LPT2)
6 * 11 Floppy Disk Controller
7 * 7 Printer Port (LPT1)
8 N/A System CMOS/Real Time Clock

9 * 10 ACPI Mode when enabled
10 * 3 IRQ Holder for PCI Steering
11 * 2 IRQ Holder for PCI Steering
12 * 4 PS/2 Compatible Mouse Port
13 N/A Numeric Data Processor
14 * 5 Primary IDE Channel
15 * 1 Secondary IDE Channel

* These IRQs are usually available for ISA or PCI devices.

2-6-1 Connectors

(1) Power Connector (20-pin block) : ATXPOW

ATX Power Supply connector. This is a new defined 20-pins connector that usually

comes with ATX case. The ATX Power Supply allows to use soft power on momentary
switch that connect from the front panel switch to 2-pins Power On jumper pole on the
