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 designed by AOpen, please
follow the following steps to install CPU cooler.
1.
First, please check the all parts are in the CPU cooler’s box. You might
get one thermal compound, two screws, CPU Fan, and the thermal heat
sink. If you didn’t get any of them, please contact with local AOpen
technical support team directly.
2.
Plug the CPU Fan into the top of the heat sink. After that, please lock
the screws between the CPU Fan and heat sink.

5. Smear over the thermal compound under the heat sink smoothly and let it be
well mixed.
6. Put the CPU cooler on the processor and lock the four screws of the heat sink.
Please make sure the screws are well tied between the motherboard and heat
sink.

Installing Memory Modules
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.

Maximum The Performance of the Dual Channel
To obtain the highest performance of Dual Channel, the configuration of DIMM
must meet the following conditions.
MatchedDIMM configuration in each channel
● Same density (128MB~1GB)
As long as you insert memory modules of same density into Channel 1 (DIMM1
& DIMM3) and Channel 2 (DIMM2 & DIMM4), dual channel mode will be
enabled.
DIMM1 + DIMM3 = DIMM2 + DIMM4
Ex: if you insert 1GB memory module into DIMM1 and DIMM3, dual channel
mode will be enabled when DIMM2 + DIMM4 = 1GB
● Same DRAM bus width (x8 or x16)
● Either single-sided or double-sided
Note: Using memory modules of different chip will
cause system unstable.
When dual channel mode is successfully enabled, the screen will show “Dual
Channel Mode Enabled” while entering POST screens.

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 24-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.
Note: Please aim the power plug at the left side of the 24-pin ATX power
connector when the foolproof design faces you as shown.

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
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, 7x… 17x, 18x, 20x
CPU FSB (Adjustment manually)
FSB = 100MHz - 400MHz by 1MHzStepping CPU Overclocking

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 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 Port0 (SATA1) will be set as the first boot device
automatically.
SATA1
SATA2
SATA3
SATA4
22
Adjusting your Hard Disk Setting
Except its original 1 set of parallel IDE, this motherboard supports the latest serial
ATA hard disk. If you are unable to find your newly installed serial ATA hard disks
on your operating system after having them installed, the problem may lie in the
BIOS setting. You can simply adjust BIOS settings to have them work properly.
After installing your hard disks properly, you can directly go to BIOS setting
screen for adjustment. Simply pressing “Integrated Peripherals Æ OnChip IDE Device Æ On-Chip Serial ATA” to choose your preferable mode. If you
have no intention of changing its original setting, the default would be Auto.
