3.2 Installation You Have to Know
Installing CPU
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 the 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 CPU socket screw clockwise to fasten CPU.

Installing CPU Cooler
This motherboard comes with a special CPU cooler desiged by AOpen, please
follow the following steps to install CPU cooler.
1. Please apply thermal paste on the bottom of CPU cooler.
2. Gently put CPU cooler onto the CPU retention module.

Installing CPU and System Fans
Plug the CPU fan cable to the 3-pin CPUFAN connector. If you have chassis fan,
you can also plug it in SYSFAN1 connector.

Note: Some CPU fans
do not have sensor pin so
that they cannot support fan

Installing Memory Modules
DIMM slots are designed in black 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 clip to hold the
DIMM in place when the DIMM
touches the slot’s bottom.

Connecting IDE and Floppy Cables
Connect the 34-pin floppy cable and 40-pin, 80-wire IDE cable to floppy
connector and IDE connector. Be careful of the pin1 orientation. Wrong
orientation may cause system damage.

Connecting Front Panel Cable
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 housing, which is a 2-pin female
connector from the housing front panel. Plug this connector to the soft-power
switch connector marked SPWR.

Connecting ATX Power Cables
This motherboard comes with a 20-pin and 4-pin ATX power connector as shown
below. Make sure you plug them in the right direction. We strongly recommend
you to insert the 4-pin connector before connecting the 20-pin connector.

3.3 Other Installation for Your Reference
Setting CPU Voltage and Frequency
Setting CPU Core Voltage
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 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!!)
B IOS Setup > Frequency / Voltage Control > CPU Bus Frequency
CPU Ratio 4x, 7x… 17x, 18x, 20x
CPU FSB
(Adjustment manually)
FSB = 100MHz - 400MHz by 1MHz

Connecting Serial ATA
To connect a serial ATA disk, you have to have a 7-pin serial ATA cable. Connect
two ends of the serial AT A cable to the serial A T A 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 AT A hard disks are installed on serial
AT A ports, the one connected on P ort0 (SA T A1) will be set as the first boot device
automatically.

SATA2
Please note that it doesn’t support Hot-Plug in function.

Connecting AGP 4X Expansion Slot
This motherboard provides an AGP 4X slot. The AGP 4X is a bus interface targeted
for high-performance 3D graphic, and the data transfer rate could achieve 66MHz
x 4bytes x 4 = 1056MB/s.
