Pin 1

This socket supports FC-LGA4 CPU, which is the latest CPU package developed by

Intel. Other forms of CPU package are impossible to be fitted in.

1. Pull CPU socket lever and plate up.

2. Remove plastic cap from CPU

socket plate.

3. Locate Pin 1 in the socket and look

for a golden arrow on the CPU

upper interface. Match Pin 1 and

golden arrow. Then insert the CPU

into the socket.

4. Press down CPU socket plate and

lever to finish CPU installation.

3. Installing Memory Modules

2. Installing CPU & System Fans

1. Installing CPU

Plug in the CPU fan cable to the 4-pin CPUFAN connector. If you have chassis fan,

you can also plug it in SYSFAN1 or SYSFAN2 connector.

DIMM slots are designed in balck and navy blue which are very easy to recognize.

Insert the module straight down to the DIMM slot with both hands and press down

firmly until the DIMM module is securely in place.

4. Connecting IDE and Floppy Cables

Connect 34-pin floppy cable and 40-pin, 80-wire IDE cable to floppy connector FDD

and IDE connector. Be careful of the pin1 orientation. Wrong orientation may cause

system damage.

FDD Connector

Note: Some CPU fans

do not have sensor pin so

they cannot support fan

monitoring.

Warning: If you do not match the CPU

socket Pin 1 and CPU golden arrow well, you

may damage the CPU. And please don’t

touch CPU socket pins when installing CPU.

(iTE IT8211F)

This motherboard comes with a 24-pin and 4-pin ATX power connector as shown

below. Make sure you plug in the right direction. We strongly recommend you to

insert the 4-pin connector before connecting the 24-pin connector.

After you finish the setting of jumpers and connect correct cables. Power

on and enter the BIOS Setup, press <Del> during POST (Power On Self

Test). Choose "Load Setup Defaults" for recommended optimal

performance.

5. Connecting Front Panel cable

6. Connecting ATX Power Cables

Attach the power LED, speaker, and reset switch connectors to the corresponding

pins. If you enable “Suspend Mode” item in BIOS Setup, the ACPI & Power LED

will keep flashing while the system is in suspend mode.

Locate the power switch cable from your ATX housing. It is 2-pin female

connector from the housing front panel. Plug this connector to the soft-power

switch connector marked SPWR.

7. Power-on and Loading BIOS Setup

8. AOpen EzInstall and Bonus Pack CD

You can use the autorun menu of Bonus CD disc. Choose the utility and driver

from the icons at left side, and then click on the “GO” button to complete

installation automatically.

Warning: Please avoid of using "Load Turbo Defaults", unless you are sure your

system components (CPU, RAM, HDD, etc.) are good enough for turbo setting.

Setting CPU Voltage & Frequency

tage

This motherboard supports Voltage ID (VID) function to detect CPU voltage

automatically during power-on. It’s not necessary to set CPU core voltage.

Setting CPU Frequency

This motherboard is CPU jumper-less design, you can set CPU frequency through

1MHz stepping CPU Overclocking in the BIOS. CPU Core Frequency = CPU FSB

clock x CPU Ratio. However, all CPU now selling in the market belong to "Fixed

Multiplier". That means users can not adjust the CPU Ratio but only change CPU

FSB clock to achieve overclocking.

(Users do the overclocking at their own risk!!)

BIOS Setup > Frequency / Voltage Control > CPU Speed Setup

CPU Ratio 8x, 10x… 24x, 25x, 26x, 27x, 28x

CPU FSB

(Adjustment manually)

FSB = 100MHz-400MHz by 1MHz Stepping CPU Overclocking

JP14 Clear CMOS

JP28 Keyboard/Mouse Wakeup Jumper

This motherboard provides keyboard / mouse wake-up function. You can use JP28

to enable or disable this function, which could resume your system from suspend

mode with keyboard or mouse. The factory default setting is “Disable” (1-2), and

you may enable this function by setting the jumper to 2-3.

You can clear CMOS to restore system default setting. To clear the CMOS, follow

the

rocedure below.

Pin 1

Note:

Some CPU

fans do not

have sensor

pin so they

cannot

support fan

monitoring.

Warning: Intel 945G / 945P chipset support maximum 1066MHz (266MHz*4)

system bus; higher clock setting may cause serious system damage.

Tip: When should I Clear CMOS?

1. Boot fails because of overclocking…

2. Forget password…

3. Troubleshooting…

1. Turn off the system and unplug the AC

power.

2. Remove ATX power cable from

connector PWR3.

3. Locate JP14 and short pins 2-3 for a few

seconds.

4. Return JP14 to its normal setting by

shorting pin 1 & pin 2.

5. Connect ATX power cable back to

connector PWR3.

IEEE 1394 Connectors

With IEEE1394 Chip on board (AGERE 1394), having its data transfer rate up to

400Mb/s, this interface can connect to devices that require high data transferring

performance such as digital camera, scanner or others IEEE 1394 devices. Please

use appropriate cables to connect IEEE1394 devices.

Gigabit LAN onboard

On the strength of Realtek Gigabit LAN chip on board, the motherboard provides

10/100/1000Mbps Ethernet for home and office use. The Ethernet RJ45 connector

is located on top of USB connectors. The right hand side LED indicates link mode,

it lights in yellow whenever linking to network. The left hand side LED indicates the

transfer mode and it lights in green when data is transferring in 100Mbps (never

lights while in 10Mbps), but lights in orange when transferring in Gigabit’s mode.

To enable or disable this function, you may simply adjust it through BIOS.

Front Audio Connectors

If the housing has been designed with an audio port on the front panel, you’ll be

able to connect onboard audio to front panel through this connector. By the way,

please remove 5-6 and 9-10 jumper caps from the Front Audio Connector before

connecting the cable. Please do not remove these 5-6 and 9-10 yellow jumper

caps if there’s no audio port on the front panel.

Serial ATA II Connectors

To connect a serial ATA II disk, you have to have a 7-pin serial ATA cable. Connect

two ends of the serial ATA II cable to the serial ATA II header on the motherboard

and the disk. Like every other traditional disk, you also have to connect a power

cable. Please be noted that it is a jumper free implement; you don’t need to set

jumpers to define a master or slave disk. When serial ATA II hard disks are

installed on serial ATA II ports, the one connected on Port0 (SATA1) will be set as

the first boot device automatically. Please note that it doesn’t support

Hot-Plug in function.
