3.2 Installation You Have to Know
Installing CPU
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 the CPU socket plate and lever to finish CPU installation.
Note: It’s strongly recommended by
Intel to use thermal paste properly to avoid
over-heat generated from Prescott CPU.

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.

Installing CPU Cooler
1. Gently put down the CPU fan on CPU socket with four sticks aiming correctly
to the four mounting holes.
2. Press down four fixing sticks into the holes one by one. Make sure the
sticks are firmly fixed into the holes.
Note: The picture above may look different from the product
you purchased.

Installing CPU and System Fans
Plug 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.
Note: Some CPU fans
do not have sensor pin so
that they cannot support fan
monitoring.

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.
Note: The tabs of the
DIMM slot will clip to hold the
DIMM in place when the DIMM
touches the slot’s bottom.

Maximum The Performance of the Dual Channel
To obtain the highest performance of Dual Channel, the configuration of DIMM
must meet the following conditions.
Matched DIMM configuration in each channel
●Same density (128MB~1GB)
As long as you insert memory modules of same density into Channel 1 (DIMM
A1 & DIMM A2) and Channel 2 (DIMM B1 & DIMM B2), dual channel mode will
be enabled.
DIMM A1 + DIMM A2 = DIMM B1 + DIMM B2
Ex: if you insert 1GB memory module into DIMM A1 and DIMM A2, dual channel
mode will be enabled when DIMM B1 + DIMM B2 = 1GB
●Same DRAM bus width (x8 or x16)
●Either single-sided or double-sided
When dual channel mode is successfully enabled, the screen will show “Dual
Channel Mode Enabled” while entering POST screens.
Note: Using memory modules of different chip will
cause system unstable.

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 24-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. It’s not necessary to set CPU core voltage.
Setting CPU Frequency
This motherboard is CPU jumper-less design; you can set CPU frequency by 1MHz
stepping CPU Overclocking in the BIOS. CPU Core Frequency = CPU FSB clock
x CPU Ratio. However, all CPU now sold in market belong to "Fixed Multiplier".
That means users can not adjust the CPU Ratio but change CPU FSB clock to
achieve overclocking only.

Connecting Serial ATA II
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.

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 ÆOnChip
IDE Device ÆOn-Chip Serial ATA” to choose your preferable mode. If you
have no intention of changing its original setting, the default would be Auto.
