Environmental Safety Instruction

z Avoid the dusty, humidity and temperature extremes. Do not place the product in any

area where it may become wet.

z 0 to 40 centigrade is the suitable temperature. (The figure comes from the request of

the main chipset)

z Generally 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.

z The 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.

z Attention 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® Pentium® Dual Core Processor，Intel® Core 2 Quad, Intel® Core 2 Duo®
(Code Name: Conroe) 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 with the advantages of the new
generation dual core Intel® Core 2 Duo® Processor for those who demand the best
experience of personal computing.

The motherboards implement Intel G41 Express Chipset which supports Front Side
Bus 1333MHz of data transferring. The model MI5-G41SGMD2-LF supports
dual-channel DDRII 667/DDRII 800 memory module with capacity expandable to 8GB
while MI5-G41SGMD3-LF supports dual-channel DDRIII 800 /DDRIII 1066MHz RAM
Module expandable to 8GB. The motherboard is embedded with ICH7 chipset of
providing one parallel Ultra ATA 100 interface for one IDE drives and 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 PCI Express x1 I/O slots and two
32-bit PCI slots guarantee the rich 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. The embedded Realtek ALC662 chipset is fully compatible with Sound Blaster
Pro standards providing HD audio 6-CH CODEC offers you with the home cinema
quality and satisfying software compatibility.

Embedded USB controller as well as capability of expanding to 8 of USB2.0 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/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

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 in working.

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

The working temperature is from 55 degrees Centigrade below zero to 125 degrees
Centigrade, Solid 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.
