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 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 SYSFAN2 connector.
Note: Some CPU fans do
not have sensor pin so that
they cannot support fan
monitoring.

Installing Memory Modules
DDRII slots are designed in black and DDR slots are designed in blue. 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.
Note: If you only have one
DDR DIMM , please plug it from
the first DIMM slot that is near
CPU

Connecting IDE and Floppy Cables
Connect the 25-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.
17
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
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

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

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.
Note 1: SATA1 and SATA2 don’t support Hot-Plug in function.
SATA3 and SATA4 support Hot-Plug
Note 2: SATA1 and SATA2 support SATA I
SATA3 and SATA4 support SATA II

Connecting PCI express x16 Graphics Slot
This motherboard provides a PCI Express x 16 Graphics slot, a black slot having
the latest PCI Express x 16 specification on motherboard. The PCI Express x 16 is
a bus interface targeted for high-performance 3D graphic. T raditionally AGP used
both rising and falling edge of the 66MHz clock for 8X AGP, and the data transfer
rate could achieve 2.1GB/s. Now PCI Express x 16 is moving to higher data
transfer rate, which is upgraded to 8.0GB/s (250MB/s x 16 x 2, it’s 4.0GB/s per
direction)..
