The motherboard comes with a 775-pin surface mount Land Grid Array (LGA)
socket designed for the Intel®Pentium® D, Intel®Pentium®4 or Intel®Celeron®
processor in the 775-land package. The motherboard supports the Intel® Pentium
® 4 or Intel®Pentium® D processor with 1066/800/533 MHz Front Side Bus (FSB).
The motherboard also supports the Intel®Hyper-Threading Technology and is
fully compatible with Intel®PCG
04B/04A and 05B/05A processors. See page 1-9 for details.
Intel®65nm Dual-Core Technology CPU support
This motherboard supports Intel®Pentium®D/Pentium®4/Celeron®dual-core
processors built on the 65-nanometer (nm) process technology with copper
interconnect.

i945G-IGM 1-3
Intel®945G chipset
The Intel®945G graphics memory controller hub (GMCH) and the ICH7 DH
I/O controller hub provide the vital interfaces for the motherboard. The GMCH
features the Intel® Graphics Media Accelerator 950, an integrated graphics engine
for enhanced 3D, 2D, and video capabilities. The GMCH provides the interface for
a processor in the 775-land package with 533/800/1066 MHz front side bus (FSB),
dual channel DDR2 at speeds of up to 667 MHz, and PCI Express x16 graphics
card.
The Intel® ICH7 DH Southbridge represents the seventh generation I/O controller
hub that provides the interface for PCI Express and 8-channel high denition
audio.
Intel®Viiv™ Technology support
Intel® Viiv™ Technology transforms your PC into an entertainment center, allowing
you to enjoy and share digital multi-media content like never before. With Intel
® Viiv™ Technology-based computers, you can record, playback, organize, and
edit digital media content easily. Enjoy the entertainment experience even more
with sharp graphics, awless video playback, and support for up to 7.1 channel
surround sound. To enable Intel® Viiv™ Technology, make sure you enable the
Quick Resume function called Energy Lake in the BIOS. Refer to the BIOS
screen on page 2-33. You also need to install the Intel® Viiv™ Technology driver
and software. See pages 3-4 and 3-5 for details.
Enabling Intel Viiv platform also requires:
- Intel®Pentium®D processor or Intel®Pentium® processor Extreme Edition
- Native Command Queuing (NCQ) SATA hard drive
- Microsoft Windows XP Media Center Edition Update Rollup 2 Refer to www.Intel.
com for more information.
DDR2 memory support
The motherboard supports DDR2 memory which features data transfer rates of
600 MHz (FSB 800) or 533 MHz (FSB 1066/800) to meet the higher bandwidth
requirements of the latest 3D graphics, multimedia, and Internet applications. The
dual-channel DDR2 architecture doubles the bandwidth of your system memory to
boost system performance, eliminating bottlenecks with peak bandwidths of up to
8.5 GB/s. See pages 1-16 to 1-18 for details.
Dual-core processors contain two physical CPU cores with dedicated L2 caches
to meet demands for more powerful processing. Intel®’s 65nm process is the most
advanced chip manufacturing technology, delivering breakthrough performance,
enhanced media experience, and low power consumption. Intel®65nm dual-core
processors utilize the latest package technologies for a thinner, lighter design
without compromising performance.

1-4 Chapter 1: Product introduction
PCI Express™ interface
The motherboard fully supports PCI Express, the latest I/O interconnect technology
that speeds up the PCI bus. PCI Express features point-to-point serial
interconnections between devices and allows higher clockspeeds by carrying data
in packets. This high speed interface is software compatible with existing PCI
specications. See page 1-22 for details.
64-bit CPU support
The motherboard supports 64-bit processors that provides high-performance
computing and faster memory access required for memory and data intensive
applications.
Serial ATA technology
The motherboard supports the Serial ATA technology through the Serial ATA
interfaces and the Intel® ICH7 DH chipset. The SATA specication allows for
thinner, more exible cables with lower pin count, reduced voltage requirement,
and up to 300 MB/s data transfer rate.
8-channel high denition audio
The onboard Realtek® ALC882 8-channel high-denition audio CODEC provides
192 KHz/ 24-bit audio output, jack-sensing and restasking functions. With the
8-channel audio ports and S/PDIF interfaces, you can connect your computer to
home theater decoders to produce crystal-clear digital audio.
S/PDIF digital sound ready
The motherboard supports the S/PDIF Out function through the S/PDIF interfaces at
midboard. The S/PDIF technology turns your computer into a high-end entertainment
system with digital connectivity to powerful audio and speaker systems. See page
1-31 for details.
Temperature, fan, and voltage monitoring
The CPU temperature is monitored by the ASIC (integrated in the Winbond Super
I/O) to prevent overheating and damage. The system fan rotations per minute (RPM)
is monitored for timely failure detection. The ASIC monitors the voltage levels to
ensure stable supply of current for critical components. See pages 2-32 and 2-33
for details.

i945G-IGM 1-5
Onboard LED
The motherboard comes with a standby power LED that lights up to indicate
that the system is ON, in sleep mode, or in soft-off mode. This is a reminder
that you should shut down the system and unplug the power cable before
removing or plugging in any motherboard component. The illustration below
shows the location of the onboard LED.
1.4 Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
• Unplug the power cord from the wall socket before touching any
component.
• Use a grounded wrist strap or touch a safely grounded object or a metal
object, such as the power supply case, before handling components to
avoid damaging them due to static electricity
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded antistatic
pad or in the bag that came with the component.
• Before you install or remove any component, ensure that the ATX
power supply is switched off or the power cord is detached from
the power supply. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.

1.5 Motherboard overview
Before you install the motherboard, study the conguration of your chassis to
ensure that the motherboard ts into it.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so can cause you physical injury and damage
motherboard components.
Do not overtighten the screws! Doing so can damage the motherboard.
1.5.1 Placement direction
When installing the motherboard, make sure that you place it into the chassis in
the correct orientation. The edge with external ports goes to the rear part of the
chassis as indicated in the image below.
1.5.2 Screw holes
Place eight (8) screws into the holes indicated by circles to secure the
motherboard to the chassis.

1-8 Chapter 1: Product introduction
1.6.1 Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
1.6 Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA775 socket designed for the
Intel®Pentium®4 processor in the 775-land package.
• Your boxed Intel®Pentium® 4 LGA775 processor package should
come with installation instructions for the CPU, fan and heatsink assembly.
If the instructions in this section do not match the CPU documentation,
follow the latter.
• Upon purchase of the motherboard, make sure that the PnP cap is on the
socket and the socket pins are not bent. Contact your retailer immediately
if the PnP cap is missing, or if you see any damage to the PnP cap/socket
pins/motherboard components. ADVANSUS will shoulder the cost of
repair only if the damage is shipment/transit-related.
• Keep the cap after installing the motherboard. ADVANSUS will process
Return Merchandise Authorization (RMA) requests only if the motherboard
comes with the cap on the LGA775 socket.
• The product warranty does not cover damage to the socket pins resulting
from incorrect CPU installation/removal, or misplacement/loss/incorrect
removal of the PnP cap.
Before installing the CPU, make sure that the socket box is facing towards you
and the load lever is on your left.

3. Lift the load lever in the direction of
the arrow to a 135º angle.
4. Lift the load plate with your thumb
and forenger to a 100º angle (A),
then push the PnP cap from the load
plate window to remove (B).
To prevent damage to the socket pins, do not remove the PnP cap unless you
are installing a CPU.
5. Position the CPU over
the socket, making sure
that the gold triangle is
on the bottom-left corner
of the socket. The socket
alignment key should t into
the CPU notch.
2. Press the load lever with your thumb (A) and move it to the left (B) until it is
released from the retention tab.
