This socket supports uFCPGA & uFCBGA package CPU, which is the latest CPU
package developed by Intel. Other forms of CPU package are impossible to be
fitted in. 1. Unscrew socket screw counter-
clockwise.
2. 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.
3. Lock the socket screw clockwise
to fasten CPU.

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 black 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.
Note: The tabs of the DIMM slot will close-up to
hold the DIMM in place when the DIMM touches the
slot’s bottom.

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.

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.

Tip: When you fail to overclock, you could:
1. Clear CMOS (JP14) to restore the default
setting.
2. After turning power on, press “Home”
immediately until the screen appears.
Setting CPU Voltage & Frequency 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
p
rocedure below.

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.

This motherboard supports Voltage ID (VID) function to detect CPU voltage
automatically during power-on.
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 external
frequency 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 Bus Frequency
CPU Ratio 4x, 5x… 17x, 18x, 20x
CPU FSB
(Adjustment manually)
FSB = 400MHz - 533MHz by 1MHz

Note:With CPU speed changing rapidly, there might be faster
CPU on the market by the time
you received this installation guide. This table is kindly for your references only.
Warning: Intel 915G
chipset support maximum
533MHz (133MHz*4) system bus;
higher clock setting may cause
serious system damage.

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.
Pin 1
Gigabit LAN onboard
On the strength of Marvell 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.

Green 100Mbps
Orange Gigabit mode

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 Connectors
To connect a serial ATA disk, you have to have a 7-pin serial ATA cable. Connect
two ends of the serial ATA cable to the serial ATA 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 hard disks are installed on serial
ATA ports, the one connected on SATA1 will be set as the first boot device
automatically. Please note that it doesn’t support Hot-Plug in function.
