• Memory modules have a foolproof design. A memory module can be installed in only one direction. If you are unable to insert the memory, switch the direction.
1-4-1 Dual Channel Memory Conguration
This motherboard provides four DDR3 memory sockets and supports Dual Channel Technology. After the
memory is installed, the BIOS will automatically detect the specications and capacity of the memory. Enabling Dual Channel memory mode will double the original memory bandwidth.
The four DDR3 memory sockets are divided into two channels and each channel has two memory sockets as
following:
Due to chipset limitation, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.
2. When enabling Dual Channel mode with two or four memory modules, it is recommended that
memory of the same capacity, brand, speed, and chips be used and installed in the same colored
DDR3 sockets for optimum performance.
• Each channel can only t one memory module when using DDR3 2200 MHz memory module.
• When memory modules of different capacity and chips are installed, a message which says
memory is operating in Flex Memory Mode will appear during the POST. Intel Flex Memory
Technology offers greater exibility to upgrade by allowing different memory sizes to be popu
lated and remain in Dual Channel mode/performance.

- 23 -Hardware Installation
1/2) ATX_12V_2X4/ATX (2x2 12V Power Connector and 2x12 Main Power Connector)
With the use of the power connector, the power supply can supply enough stable power to all the
components on the motherboard. Before connecting the power connector, rst make sure the power
supply is turned off and all devices are properly installed. The power connector possesses a foolproof
design. Connect the power supply cable to the power connector in the correct orientation. The 12V
power connector mainly supplies power to the CPU. If the 12V power connector is not connected, the
computer will not start.
To meet expansion requirements, it is recommended that a power supply that can withstand high
power consumption be used (500W or greater). If a power supply is used that does not provide
the required power, the result can lead to an unstable or unbootable system.
The motherboard has a 4-pin CPU fan header (CPU_FAN), a 4-pin (SYS_FAN2) and a 3-pin (SYS_FAN1)
system fan headers, and a 3-pin power fan header (PWR_FAN). Most fan headers possess a foolproof
insertion design. When connecting a fan cable, be sure to connect it in the correct orientation (the black
connector wire is the ground wire). The motherboard supports CPU fan speed control, which requires
the use of a CPU fan with fan speed control design. For optimum heat dissipation, it is recommended
that a system fan be installed inside the chassis.

10) BAT (BATTERY)
The battery provides power to keep the values (such as BIOS congurations, date, and time information)
in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a
low level, or the CMOS values may not be accurate or may be lost.
You may clear the CMOS values by removing the battery:
1. Turn off your computer and unplug the power cord.
2. Gently remove the battery from the battery holder and wait for one minute.
(Or use a metal object like a screwdriver to touch the positive and negative
terminals of the battery holder, making them short for 5 seconds.)
3. Replace the battery.
4. Plug in the power cord and restart your computer.
• Always turn off your computer and unplug the power cord before replacing the battery.
• Replace the battery with an equivalent one. Danger of explosion if the battery is replaced with an
incorrect model.
• Contact the place of purchase or local dealer if you are not able to replace the battery by yourself or
uncertain about the battery model.
• When installing the battery, note the orientation of the positive side (+) and the negative side (-) of the
battery (the positive side should face up).
• Used batteries must be handled in accordance with local environmental regulations.

11) F_PANEL (Front Panel Header)
Connect the power switch, reset switch, speaker, chassis intrusion switch/sensor and system status
indicator on the chassis to this header according to the pin assignments below. Note the positive and
negative pins before connecting the cables.
Connects to the power status indicator on the chassis front panel. The LED
is on when the system is operating. The LED keeps blinking when the system is in S1 sleep state. The LED is off when the system is in S3/S4 sleep
state or powered off (S5).
•PW (Power Switch, Red):
Connects to the power switch on the chassis front panel. You may congure the way to turn off your
system using the power switch (refer to Chapter 2, "BIOS Setup," "Power Management Setup," for
more information).
•SPEAK (Speaker, Orange):
Connects to the speaker on the chassis front panel. The system reports system startup status by is-
suing a beep code. One single short beep will be heard if no problem is detected at system startup. If
a problem is detected, the BIOS may issue beeps in different patterns to indicate the problem. Refer
to Chapter 5, "Troubleshooting," for information about beep codes.
•HD (Hard Drive Activity LED, Blue)
Connects to the hard drive activity LED on the chassis front panel. The LED is on when the hard drive
is reading or writing data.
•RES (Reset Switch, Green):
Connects to the reset switch on the chassis front panel. Press the reset switch to restart the computer
if the computer freezes and fails to perform a normal restart.
•CI (Chassis Intrusion Header, Gray):
Connects to the chassis intrusion switch/sensor on the chassis that can detect if the chassis cover
has been removed. This function requires a chassis with a chassis intrusion switch/sensor.
The front panel design may differ by chassis. A front panel module mainly consists of power
switch, reset switch, power LED, hard drive activity LED, speaker and etc. When connecting your
chassis front panel module to this header, make sure the wire assignments and the pin assignments are matched correctly.
