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.
Environmental Protection Announcement
Do not dispose this electronic device into the trash while discarding. To minimize pollution
and ensure environment protection of mother earth, please recycle.

Introduction of Intel G41 Motherboard Series
1-1 Features of Motherboard
The Intel G41 chipset motherboard series are based on the latest Intel G41 Express
Chipset and Intel ICH7 Chipset technology which supports the innovative 65nm and
90nm Intel®Core 2 Quad, Intel®Core 2 Duo®(Code Name: Conroe) Processor, Intel®
Pentium®Dual Core Processor, Celeron®Dual Core Processor and Celeron®400
Processor with Intel®Hyper-Threading Technology and fully supports the future 45nm
processors. The motherboard is optimized to deliver innovative features and
professional desktop platform solution for those who demand the best experience of
personal computing.
The motherboard series implement Intel G41 Express Chipset which supports Front
Side Bus 1333MHz of data transferring. The motherboard series support dual-channel
DDRIII 1066/1333MHz RAM Module expandable to 4GB. The motherboards are
embedded with ICH7 chipset of four serial ATA2 interface of 3Gb / s data transfer rate
for four serial ATA devices.
The G41 motherboard series offer one PCI-Express x16 graphics slot of 8Gbyte/sec
data transfer rate at each relative direction which gets 7 times of bandwidth more than
AGP 8X and up to 16Gbyte/sec peak concurrent bandwidth at full speed to guarantee
the ultimate GPU computing performance. One 32-bit PCI slot also enriches
connectivity for the I/O of peripherals. The motherboards are designed of tackling the
profuse multimedia requirements nowadays.
The motherboards provide 10/100 Ethernet LAN function by using the PCI-E megabit
LAN Chip. The embedded 6-CH HD Audio chip is fully compatible with Sound Blaster
Pro standards providing 6-CH HD audio CODEC offers you with the home cinema
quality and satisfying software compatibility.
Embedded USB controller as well as capability of expanding to 8 USB 2.0 functional
ports delivering 480Mb/s of rich connectivity, these motherboards meet the demands
of future USB peripherals which are also equipped with hardware monitor function on
system to monitor and protect your system and maintain your non-stop business
computing.
Some special features---CPU Thermal Throttling/CPU Vcore Output OC-CON in
this motherboard are designed for power user to use the over-clocking function in
more flexible ways. But please be caution that the over-clocking maybe causes the
fails in system reliabilities. This motherboard provides the guaranteed performance
and meets the demands of the next generation computing. But if you insist to 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--- 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.
CPU Smart Fan—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 Output Solid Capacitors---High-polymer Solid Electrolysis Aluminum
Capacitors
CPU Vcore Input and Output of the motherboard adopts OC-CON solid capacitors to
make it possible for motherboard to work from 55 degrees Centigrade below zero to
125 degrees centigrade. OC-CON capacitors possess superior physical
characteristics to prolong product life ten times than corresponding motherboard
without capacitors every time working temperature increases 20 degrees. Life of
product of motherboard with solid capacitors declines only 10% of those without solid
capacitors as well under same conditions.

2-3 CPU Installation
This motherboard provides a 775-pin surface mount, LGA775 Land Grid Array socket,
referred to as the LGA775 socket supports Intel Pentium Dual Core processor in the
775 Pin package utilizes Flip-Chip Land Grid Array (FC-LGA) 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! 1.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.
2
. Suggest the power of CPU should below 65w.
To install a CPU, first turn off your system and remove its cover. Locate the LGA775
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.
