Chapter 2: Installation
This is a Micro ATX form factor (9.6" x 9.6", 24.4 x 24.4 cm) motherboard. Before
you install the motherboard, study the conguration of your chassis to ensure that
the motherboard ts into it.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so may cause physical injuries to you and
damages to motherboard components.
2.1 Screw Holes
Place screws into the holes to secure the motherboard to the chassis.
Do not over-tighten the screws! Doing so may damage the motherboard.
2.2 Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component.
2. To avoid damaging the motherboard components due to static electricity,
NEVER place your motherboard directly on the carpet or the like. Also
remember to use a grounded wrist strap or touch a safety grounded object
before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded antistatic pad or
in the bag that comes with the component.
Before you install or remove any component, ensure that the power is
switched off or the power cord is detached from the power supply.
Failure to do so may cause severe damage to the motherboard, peripherals,
and/or components.

2.3 Installation of Memory Modules (DIMM)
This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM
slots, and supports Dual Channel Memory Technology. For dual channel con-
guration, you always need to install identical (the same brand, speed, size
and chip-type) DDR3 DIMM pair in the slots of the same color. In other words,
you have to install identical DDR3 DIMM pair in Dual Channel (DDR3_A1 and
DDR3_B1; Blue slots) or identical DDR3 DIMM pair in Dual Channel (DDR3_
A2 and DDR3_B2; White slots), so that Dual Channel Memory Technology can
be activated. This motherboard also allows you to install four DDR3 DIMMs for
dual channel conguration, and please install identical DDR3 DIMMs in all four
slots. You may refer to the Dual Channel Memory Conguration Table below.
Dual Channel Memory Congurations
DDR3_A1 DDR3_A2 DDR3_B1 DDR3_B2
(Blue Slot) (White Slot) (Blue Slot) (White Slot)
(1) Populated - Populated -
(2) - Populated - Populated
(3)* Populated Populated Populated Populated
* For the conguration (3), please install identical DDR3 DIMMs in all four
slots.
1. If you want to install two memory modules, for optimal compatibility
and reliability, it is recommended to install them in the slots of the
same color. In other words, install them either in the set of blue
slots (DDR3_A1 and DDR3_B1), or in the set of white slots (DDR3_
A2 and DDR3_B2).
2. If only one memory module or three memory modules are installed
in the DDR3 DIMM slots on this motherboard, it is unable to activate
the Dual Channel Memory Technology.
3. If a pair of memory modules is NOT installed in the same Dual
Channel, for example, installing a pair of memory modules in
DDR3_A1 and DDR3_A2, it is unable to activate the Dual Channel
Memory Technology .
4. It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot; otherwise, this motherboard and DIMM may be dam-
aged.
5. Some DDR3 1GB double-sided DIMMs with 16 chips may not work
on this motherboard. It is not recommended to install them on this
motherboard.

13
notch
break
notch break
Installing a DIMM
Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align a DIMM on the slot such that the notch on the DIMM matches the
break on the slot.
The DIMM only ts in one correct orientation. It will cause permanent
damage to the motherboard and the DIMM if you force the DIMM into
the slot at incorrect orientation.
Step 3. Firmly insert the DIMM into the slot until the retaining clips at both ends
fully snap back in place and the DIMM is properly seated.

14
2.4 Expansion Slots (PCI, PCI Express and mini-PCIe Slots)
There are 2 PCI slots, 2 PCI Express slots and 1 mini-PCIe slot on this
motherboard.
PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI
interface.
PCIE slots:
PCIE1 (PCIE x16 slot; Blue) is used for PCI Express x16 lane width
graphics cards.
PCIE2 (PCIE x4 slot; White) is used for PCI Express x4 lane width
graphics cards.
MINI_PCIE1 (mini-PCIe slot) is used for PCI Express mini cards.
Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power
supply is switched off or the power cord is unplugged. Please read the
documentation of the expansion card and make necessary hardware
settings for the card before you start the installation.
Step 2. Remove the system unit cover (if your motherboard is already installed
in a chassis).
Step 3. Remove the bracket facing the slot that you intend to use. Keep the
screws for later use.
Step 4. Align the card connector with the slot and press rmly until the card is
completely seated on the slot.
Step 5. Fasten the card to the chassis with screws.
Step 6. Replace the system cover.

2.5 Jumpers Setup
The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “Short”. If no jumper cap
is placed on pins, the jumper is “Open”. The
illustration shows a 3-pin jumper whose
pin1 and pin2 are “Short” when jumper cap
is placed on these 2 pins.
Jumper Setting Description
Clear CMOS Jumper
(3-pin CLRCMOS1)
(see p.8, No. 28)
Note: CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the
system parameters to default setup, please turn off the computer and unplug
the power cord from the power supply. After waiting for 15 seconds, use a
jumper cap to short pin2 and pin3 on CLRCMOS1 for 5 seconds. However,
please do not clear the CMOS right after you update the BIOS. If you need
to clear the CMOS when you just nish updating the BIOS, you must boot up
the system rst, and then shut it down before you do the clear-CMOS action.
Please be noted that the password, date, time, user default prole and MAC
address will be cleared only if the CMOS battery is removed.

is on when the system is operating. The LED keeps blinking when the sys-
tem is in S1/S3 sleep state. The LED is off when the system is in S4 sleep
state or powered off (S5).
HDLED (Hard Drive Activity LED):
Connect to the hard drive activity LED on the chassis front panel. The LED
is on when the hard drive is reading or writing data.
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 assign-ments are
matched correctly.
System Panel Header This header accommodates
(9-pin PANEL1) several system front panel
(see p.8, No. 22) functions.
