Environmental Safety Instruction
zAvoid the dusty, humidity and temperature extremes. Do not place the product in
any area where it may become wet.
z0 to 40 centigrade is the suitable temperature. (The figure comes from the request
of the main chipset)
zGenerally speaking, dramatic changes in temperature may lead to contact
malfunction and crackles due to constant thermal expansion and contraction from
the welding spots’ that connect components and PCB. Computer should go
through an adaptive phase before it boots when it is moved from a cold
environment to a warmer one to avoid condensation phenomenon. These water
drops attached on PCB or the surface of the components can bring about
phenomena as minor as computer instability resulted from corrosion and oxidation
from components and PCB or as major as short circuit that can burn the
components. Suggest starting the computer until the temperature goes up.
zThe increasing temperature of the capacitor may decrease the life of computer.
Using the close case may decrease the life of other device because the higher
temperature in the inner of the case.
zAttention to the heat sink when you over-clocking. The higher temperature may
decrease the life of the device and burned the capacitor.

Cooling Solutions
As processor technology pushes to faster speeds and higher performance, thermal management
becomes increasingly crucial while building computer systems. Maintaining the proper thermal
environment is the 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.
Heat sinks 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 heat sink. For optimum heat transfer, Intel recommends the use of
thermal grease and mounting clips to attach the heat sink to the processor.
When selecting a thermal solution for your system, please refer to the website below for collection of
heat sinks evaluated and recommended by Intel for use with Intel processors. Note, those heat sinks
are recommended for maintaining the specified Maximum T case requirement. In addition, this
collection is not intended to be a comprehensive listing of all heat sinks that support Intel processors.

gain more system performance with variety possibilities of the components you choose,
please be careful and make sure to read the detailed descriptions of these value added product
features, please get them in the coming section.
1-1.1 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 working.
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 X-Shift--- Shift to Higher Performance
The CPU voltage can be adjusted up by 64 stages for the precisely over-clocking of extra
demanding computing performance.
OC-CON---High-polymer Solid Electrolysis Aluminum Capacitors (Optional, for HI04
series only)
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.
G.P.I Function—(Green power indicator function)
G.P.I is a technology with remarkable power saving function: when you are using a computer
with G.P.I mode turned on, you save averagely 10.5w in power consumption in the whole
process than normal computer without G.P.I technology.
3D Audio
OP with two-stage Butterworth filter and quadruple noninverting amplifier enhances bass
effect under the 100MHz range to perfect audio effect, brings you stunning shock experience
in video game, true-to-life simulated feeling when watching films and the greatest touch as

exclusively to single interface use only. There are 16 IRQs available but most of them are
already being used.
Standard Interrupt Assignments

2-5-3 PCI Express Slot
The P43 Express chipset based motherboard series offer two PCI-Express x16 graphics slots
that support CrossFireX Mode. One PCI-Express2.0 x16by16lane graphics slot offers 8
Gbyte/sec data transfer rate at each relative direction which get 7 times of bandwidth more
than AGP8X and up to 16Gbyte/sec concurrent bandwidth at full speed, the other
PCI-Express 1.0a x16by4lane graphics slots deliver up to 2Gbyte/sec data transfer rate. These
two graphics slots are fully compatible with the latest AMD CrossFireX Technology and
avoid the possible CrossFireX installation error. Two PCI Express1.0a x1 I/O slots offer
512Mbyte/sec concurrently, over 3.5 times more bandwidth than PCI at 133Mbye/sec,
tackling the most demanding multimedia tasks nowadays. Two 32-bit PCI slots guarantee the
rich connectivity for the I/O of peripherals.

2-6 Connectors, Headers
2-6-1 Connectors
(1) Power Connector (24-pin block): ATXPWR
ATX Power Supply connector: This is a new defined 24-pins connector that usually
comes with ATX case. The ATX Power Supply allows using 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 (4-pin block) : ATX12V
This is a new defined 4-pin connector that usually comes with ATX Power Supply. The
ATX Power Supply which fully supports LGA775 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.
