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® 4 Processor，Celeron 4xx Processor, Dual-Core Intel® Pentium® D Processor 8 and
9 Series, 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. Through the high bandwidth of
dual channel DDR2 533MHz/DDR2 667MHz /DDR2 800 system memories which are
expandable to 8GB.
The motherboards implement Intel G41 Express Chipset which supports Front Side Bus
1333MHz of data transferring and offers with 266/333MHz/400MHz memory clock frequency
for Dual channel DDRII533/DDRII667/DDRII800 memory DIMM to double the performance
of memory access. 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/ CPU Vcore 7-shift /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---(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.
CPU Vcore 7-Shift--- (Shift to Higher Performance)
The CPU voltage can be adjusted up by 7 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.

Hardware Installation
2-1 Install LGA 775 Supported Intel Processor
This motherboard provides a 775-pin surface mount, LGA775 Land Grid Array socket,
referred to as the LGA775 socket supports Intel Pentium 4 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.

Install DDR2 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.
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.

** 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
