absolutely the cost-effective solution for game enthusiasts and applications, and it also meets
the demanding usage of computing of gaming, multimedia entertainment and business
applications. Moreover, the Intel 946GZ express chipset incorporates Intel Graphics Media
Accelerator 3000 to provide you incredible visual quality, faster graphics performance and
flexible display options without the need for a separate graphics card.
The motherboards implement Intel 946GZ+ ICH7 Express Chipset which supports Front Side
Bus 1333MHz of data transferring and offers with 667MHz memory clock frequency for Dual
channel DDR2 400/DDR2 533/DDR2 667 MHz memory DIMMs 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 946GZ + ICH7 motherboard series offer one PCI-Express x16 graphics slot of 4Gbyte/sec
data transfer rate at each relative direction which gets 3.5 times of bandwidth more than AGP
8X and it’s up to a peak concurrent bandwidth of 8Gbyte/sec at full speed to guarantee the
ultimate GPU computing performance. 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 Mbit / 100Mbit Ethernet compatible LAN function by using the
Realtek RTL8102E10/100 PCI-E LAN chip. And the embedded ALC662 chipset fully
compatible with Sound Blaster Prostandards with providing 6-channel Azalia HD CODEC
offers you with the home cinema quality and satisfying software compatibility.
Embedded USB controller as well as capability of expanding to8 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 Smart Fan 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 Smart Fan---( The Noise Management SystemOnly support 4-pin CPU cooler )
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.

This motherboard provides a 775-pin surface mount, LGA775 Land Grid Array socket,
referred to as 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!
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.
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.

Connectors, Headers & Jumpers Setting
3-1 Connectors
(1) Power Connector (24-pin block) : ATXPWR
ATX Power Supply connector: This is a new defined 24-pins connector that usually
comes with ATX case. The ATX Power Supply allows using soft power on momentary
switch that connect from the front panel switch to 2-pins Power On jumper pole on the
motherboard. When the power switch on the back of the ATX power supply turned on,
the full power will not come into the system board until the front panel switch is
momentarily pressed. Press this switch again will turn off the power to the system
board.
** 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
power is inadequate.
(2) ATX 12V Power Connector (4-pin block) : ATX12V
This is a new defined 4-pins connector that usually comes with ATX Power Supply.
The ATX Power Supply which fully supports AM2 processor must including this
connector for support extra 12V voltage to maintain system power consumption.
Without this connector might cause system unstable because the power supply can not
provide sufficient current for system.

USEFUL HELP
4-1 HOW TO UPDATE BIOS
Before updating the BIOS, users have to check if the “Miscellaneous Control” of BIOS SETUP has
the “Flash Part Write Protect” selection. If there is one, users have to “Disable” the “Flash Part Write
Protect” selection of the “Miscellaneous Control” in BIOS SETUP. Otherwise the system the will
not allow you to upgrade BIOS by Award Flash Utility. If there is no such selection, users can follow
the 4 steps directly to update BIOS.
STEP 1. Prepare a boot disc. (You may make one by click START click RUN type SYS A: click
OK)
STEP 2. Copy utility program to your boot disc. You may copy from DRIVER CD
X:\FLASH\AWDFLASH.EXE or download from our web site.
STEP 3. Download and make a copy of the latest BIOS for 946GZ motherboard series from the web
site to your boot disc.
STEP 4. Insert your boot disc into A:,
Start the computer, type “Awdflash A:\xxxxxx.BIN /SN/PY/CD/CH/WB/CC/R”
xxxxxx.BIN is the file name of latest BIOS
SN means don’t save existing BIOS data
PY means renew existing BIOS data
CD means clear DMI data after programming
CH means update HOLE
WB means always programming BootBlock
CC means clear existing CMOS data
R means restart computer
STEP 5. Type ENTER to update and flash the BIOS, then the system will restart automatically.
4-2 Trouble Shooting
Problem Solution
No power to the system to the all power light
don’t illuminate, fan inside power supply
doesn’t turn on.
System inoperative. Keyboard lights are on ,
power indicator lights are lit, and hard drive
is spinning.
System doesn’t boot from hard disk drive,
can be booted from optical drive.
System only boots from optical drive .Hard
disk can be read and applications can be used
but booting from hard disk is impossible.
Screen message says “Invalid Configuration”
or “CMOS Failure”
Can not boot system after installing second
hard drive.
1. Make sure power cable is security plugged in.
2. Replace cable. 3. Contact technical support.
Using ever pressure on both ends of the
DIMM , press down firmly until the module
snaps into places.

controller board. .Make sure both ends are
securely plugged in, check the drive type in the
standard CMOS setup. 2. Backing up the hard
drive is extremely important .All hard disks are
capable of breaking down at any time.
1. Back up date and applications files. 2.
Reformat the hard drive. Reinstall applications
and date using backup disks.
Review system ‘s equipment .Make sure correct
information on is in setup.
