Introduction of Intel G41 Motherboard Series
1-1 Features of Motherboard
The G41 Express and ICH7 chipset motherboard series are based on Intel G41 Express chipset
and ICH7 chipsets technology which supports the innovative 45nm and 65nm Quad-Core,
Dual-Core Intel® Core 2 Quad, Core 2 Duo processors, Intel® Pentium Dual Core, Intel®
Celeron Dual Core Conroe processors and Intel® Celeron 400 Conroe-L processors.
The G41 Express and ICH7 chipset Based motherboard series deliver the revo lutionary levels
of performance enabling vivid, high-definition experiences and multi-tasking responsiveness
from state-of-the-art Intel dual-core and quad-core technologies through the high bandwidth
of dual channel DDRIII 800 / 1066MHz system memories which are expandable to 4 GB and
the next generation PCI Express interface for the latest AMD and NVIDIA graphics card .
The G41 Express and ICH7 chipset motherboard series are absolutely the ultimate solution for
game enthusiasts and applications, and it also meets the demanding usage of computing of
gaming, multimedia entertainment and business applications .
The INTEL G41 Express and ICH7 chipset motherboard series are embedded with ICH7
chipset of providing four serial ATA2 interface of 3.0 Gb / s data transfer rate for four serial
ATA devices.
The G41 Express and ICH7 chipset Based motherboard provides Gigabit LAN function by using
the Realtek RTL8111DL PCI Gigabit LAN which supports 10M / 100M / 1Gbps data transfer
rate. Embedded 8-channel ALC888 HD Audio Codec is fully compatible with Sound Blaster
Pro® standards that offer you with the home cinema quality and absolutely software
compatibility.
The G41 Express chipset based motherboard series offer one PCI-Express2.0 x16 by 16lane
graphics slots which get 7 times of bandwidth more than AGP8X. This graphics slot offers 8
Gbyte/sec data transfer rate at each relative direction and up to 16Gbyte/sec concurrent
bandwidth at full speed. Two 32-bit PCI slots guarantee the rich connectivity for the I/O of
peripherals.
Embedded USB controllers as well as capability of expanding to 8 of USB2.0 functional ports
delivering 480Mb/s bandwidth of rich connectivity, these motherboards meet the future USB
demands 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---
Audio
in this motherboard are designed for power user to use the over-clocking function in
CPU Thermal Throttling/ CPU Smart Fan/ CPU Vcore X-shift/3D
more flexible ways. But please be caution that the over-clocking may cause the failure in
system reliability. 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 Smart Fan
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.
--- The Noise Management System
CPU Vcore X-Shift
The CPU voltage can be adjusted up by 8 stages for the precisely over-clocking of extra
demanding computing performance.
--- Shift to Higher Performance
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
that in the concert.
