If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:

- REORIENT OR RELOCATE THE RECEIVING ANTENNA

- INCREASE THE SEPARATION BETWEEN THE EQUIPMENT AND THE
RECEIVER

- CONNECT THE EQUIPMENT INTO AN OUTLET ON A CIRCUIT DIFFERENT
FROM THAT OF THE RECEIVER

- CONSULT THE DEALER OR AN EXPERIENCED AUDIO/TELEVISION
TECHNICIAN

NOTE: Connecting this device to peripheral devices that do not comply with Class B

requirements, or using an unshielded peripheral data cable, could also result in
harmful interference to radio or television reception.

The user is cautioned that any changes or modifications not expressly approved
by the party responsible for compliance could void the user’s authority to operate
this equipment.

To ensure that the use of this product does not contribute to interference, it is

Special Features of Motherboard

CPU Thermal Throttling Technology

---(The CPU Overheat Protection Technology)
To prevent the increasing heat from damage of CPU or accidental shutdown while at high
workload, the CPU Thermal Throttling Technology will force CPU to enter partially idle
mode from 87.5% to 12.5% according to preset CPU operating temperature in BIOS (from 40
℃ to 90℃). When the system senses the CPU operating temperature reaching the preset
value, the CPU operating bandwidth will be decreased to the preset idle percentage to cool
down the processor. When at throttling mode the beeper sound can be optionally selected to
indicate it is in working. (For detail operating please read Section 3-11 Bi-turbo

Configuration)

CPU Smart Fan---( The Noise Management System )

It’s never been a good idea to gain the performance of your system by sacrificing its acoustics.
CPU Smart Fan Noise Management System is the answer to control the noise level needed for
now-a-day’s high performance computing system. The system will automatically increase the
fan speed when CPU operating loading is high, after the CPU is in normal operating condition,
the system will low down the fan speed for the silent operating environment. The system can
provide the much longer life cycle for both CPU and the system fans for game use and
business requirements.

CPU Vcore 7-Shift--- (Shift to Higher Performance)

The CPU voltage can be adjusted up by 31 steps for the precisely over-clocking of extra
demanding computing performance.

OC-CON ---（High-polymer Solid Electrolysis Aluminum Capacitors）

The working temperature is from 55 degrees Centigrade below zero to 125 degrees
Centigrade, OC-CON capacitors possess superior physical characteristics that can be while
reducing the working temperature between 20 degrees Centigrade each time, intact extension
10 times of effective product operation lives, at not rising degrees Centigrade of working
temperatures each time a relative one, life of product decline 10% only too.

About AMD Athlon64 Socket AM2 CPU

This motherboard provides a 940-pin surface mount, Zero Insertion Force (ZIF) socket,
referred to as the mPGA940 socket supports AMD Athlon64 processor in the 940 Pin package
utilizes Flip-Chip Pin Grid Array package technology.

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.

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.

Socket AM2

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.

3. Four DIMM Modules---Plug in DIMM1/DIMM2/DIMM3/DIMM4.

For Dual channel Limited!

4. Dual channel function only supports when 2 DIMM Modules plug in either both DIMM1 &

DIMM2or DIMM3 &DIMM4, or four DIMM Modules plug in DIMM1~DIMM4.

5. DIMM1 & DIMM2, or DIMM3& DIMM4 must be the same type, same size, same frequency

for dual channel function.

Install DDR SDRAM modules to your motherboard is not difficult, you can refer to figure
below to see how to install a 240-Pin DDR2 533/DDR2 667/DDR2 800/ SDRAM module.

DIMM3 (BANK2+BANK3)

DIMM4 (BANK0+BANK1)

DIMM1 (BANK6+BANK7)

DIMM2 (BANK4+BANK5)

DIMM1 & DIMM2: Dual Channel 1

IMM3 & DIMM4: Dual Channel 2

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.

WA RN IN G! For the DDR SDRAM CLOCK is set at 400MHz, use only DDR 2 80 0- c om p li an t DDR2

Modules. When this motherboard operate at 400Mhz, most system will not even boot if
non-compliant modules are used because of the strict timing issues, if your DDR
Modules are not DDR2 800-compliant, set the SDRAM clock to 200MHz to ensure
system stability.

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.

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.

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

that the cards don’t need IRQ assignments. Conflicts will arise between the two PCI
groups that will make the system unstable or cards inoperable.

Connectors, Headers & Jumper Setting

Connectors

(1) Power Connector (24-pin block) : ATXPWR

ATX Power Supply connector. This is a new defined 24-pins conne ctor 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
motherboard. When the power switch on the back of the ATX power supply turned on,
the full power will not come into the system board until the front panel switch is
momentarily pressed. Press this switch again will turn off the power to the system
board.

** We recommend that you use an ATX 12V Specification 2.0-compliant power supply

unit (PSU) with a minimum of 350W power rating. This type has 24-pin and 4-pin
power plugs.

** If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the 20-pin

power plug can provide at least 15A on +12V and the power supply unit has a minimum
power rating of 350W. The system may become unstable or may not boot up if the
power is inadequate.

(2) ATX 12V Power Connector (8-pin block) : ATX12V

This is a new defined 8-pins connector that usually comes with ATX Power Supply.
The ATX Power Supply which fully support Pentium 4 processor must including this
connector for support extra 12V voltage to maintain system power consumption.
Without this connector might cause system unstable because the power supply can not
provide sufficient current for system.
