Chapter 2: Installation

This is a Micro ATX form factor (9.6" x 8.0", 24.4 x 20.3 cm) motherboard. Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits 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 indicated by circles 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 CPU Installation

For the installation of Intel 1156-Pin CPU, please follow the steps below.

Load Plate

Load Lever

Contact Array

Socket Body
1156-Pin Socket Overview Before you insert the 1156-Pin CPU into the socket, please check if the CPU surface is unclean or if there is any bent pin on the socket. Do not force to insert the CPU into the socket if above situation is found. Otherwise, the CPU will be seriously damaged.
Step 1. Open the socket: Step 1-1. Disengaging the lever by depressing down and out on the hook to clear retention tab.
Step 1-2. Rotate the load lever to fully open position at approximately 135 degrees. Step 1-3. Rotate the load plate to fully open position at approximately 100 degrees.
Step 2. Remove PnP Cap (Pick and Place Cap).
1. It is recommended to use the cap tab to handle and avoid kicking off the PnP cap. 2. This cap must be placed if returning the motherboard for after service.
Step 3. Insert the 1156-Pin CPU: Step 3-1. Hold the CPU by the edge where is marked with black line.

black line

Step 3-2. Orient the CPU with IHS (Integrated Heat Sink) up. Locate Pin1 and the two orientation key notches.
orientation key notch Pin1 alignment key
Pin1 alignment key orientation key notch 1156-Pin CPU 1156-Pin Socket
For proper inserting, please ensure to match the two orientation key notches of the CPU with the two alignment keys of the socket.
Step 3-3. Carefully place the CPU into the socket by using a purely vertical motion. Step 3-4. Verify that the CPU is within the socket and properly mated to the orient keys.
Step 4. Close the socket: Step 4-1. Rotate the load plate onto the IHS. Step 4-2. While pressing down lightly on load plate, engage the load lever. Step 4-3. Secure load lever with load plate tab under retention tab of load lever.
Installation of CPU Fan and Heatsink
This motherboard is equipped with 1156-Pin socket that supports Intel 1156-Pin CPU. Please adopt the type of heatsink and cooling fan compliant with Intel 1156-Pin CPU to dissipate heat. Before you installed the heatsink, you need to spray thermal interface material between the CPU and the heatsink to improve heat dissipation. Ensure that the CPU and the heatsink are securely fastened and in good contact with each other. Then connect the CPU fan to the CPU_FAN connector (CPU_FAN1, see page 11, No. 3). For proper installation, please kindly refer to the instruction manuals of your CPU fan and heatsink. Below is an example to illustrate the installation of the heatsink for 1156-Pin CPU. Step 1. Apply thermal interface material onto center of IHS on the socket surface.

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. Remove the system unit cover (if your motherboard is already installed in a chassis). Remove the bracket facing the slot that you intend to use. Keep the screws for later use. Align the card connector with the slot and press firmly until the card is completely seated on the slot. Fasten the card to the chassis with screws. Replace the system cover.
Step 2. Step 3. Step 4. Step 5. Step 6.

2.7 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 PS2_USB_PWR1 2_3 1_2
Description Short pin2, pin3 to enable (see p.11, No. 2) +5VSB (standby) for PS/2 +5V +5VSB or I/O panel USB wake up events. Note: To select +5VSB, it requires 2 Amp and higher standby current provided by power supply. USB_PWR1 (PORT 6-9)

(see p.11, No. 19)

Short pin2, pin3 to enable +5VSB (standby) for USB6_7 and USB8_9 wake +5V +5VSB up events. Note: To select +5VSB, it requires 2 Amp and higher standby current provided by power supply.

1_2 2_3

Clear CMOS Jumper
(CLRCMOS1) (see p.11, No. 16)

Default

Clear CMOS
Note: CLRCMOS1 allows you to clear the data in CMOS. The data in CMOS includes system setup information such as system password, date, time, and system setup parameters. 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 finish updating the BIOS, you must boot up the system first, and then shut it down before you do the clearCMOS action.
