Chapter 1: Product introduction |
1.4Before you proceed
Take note of the following precautions before you install motherboard components or change any motherboard settings.
• Unplug the power cord from the wall socket before touching any component.
•Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, to avoid damaging them due to static electricity.
•Hold components by the edges to avoid touching the ICs on them.
•Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.
•Before you install or remove any component, ensure that the ATX power supply 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, or components.
Onboard LED
The motherboard comes with a standby power LED that lights up to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you must shut down
the system and unplug the power cable before removing or plugging in any motherboard component. The illustration below shows the location of the onboard LED.

1.5Motherboard overview
Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it.
Ensure that you unplug the power cord before installing or removing the motherboard. Failure to do so can cause you physical injury and damage motherboard components.
1.5.1Placement direction
When installing the motherboard, ensure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis as indicated in the image below.
1.5.2Screw holes
Place six screws into the holes indicated by circles to secure the motherboard to the chassis.
Do not overtighten the screws! Doing so can damage the motherboard.
Place this side towards the rear of the chassis

1.6Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA1156 socket designed for the Intel® Core™ i7 / Core™ i5 processors.
Unplug all power cables before installing the CPU.
• Upon purchase of the motherboard, ensure that the PnP cap is on the socket and the socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket contacts/motherboard components. ASUS will shoulder the cost of repair only if the damage is shipment/transit-related.
•Keep the cap after installing the motherboard. ASUS will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with the cap on the
LGA1156 socket.
•The product warranty does not cover damage to the socket contacts resulting from incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP cap.
1.6.1Installing the CPU
To install a CPU:
1.Locate the CPU socket on the motherboard.

2.Press the load lever with your thumb (A),
and then move it to the right (B) until it is released from the retention tab.
To prevent damage to the socket pins, do not remove the PnP cap unless you are installing a CPU.

3.Lift the load lever in the direction of the arrow until the load plate is completely lifted.
4.Remove the PnP cap from the CPU socket.
5.Position the CPU over the socket, ensuring that the gold triangle is on the bottom left corner of the socket, and then fit the socket alignment keys into the CPU notches.

The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU!

6.Apply some Thermal Interface Material to the exposed area of the CPU that the heatsink will be in contact with, ensuring that it is spread in an even thin layer.
Some heatsinks come with preapplied thermal paste. If so, skip this step.
The Thermal Interface Material is toxic and inedible. DO NOT eat it. If it gets into your eyes or touches your
skin, wash it off immediately, and seek professional medical help.
7.Close the load plate (A), and then push down the load lever (B), ensuring that the front edge of the load plate slides under the retention knob (C).

1.6.2Installing the CPU heatsink and fan
The Intel® LGA1156 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance.
• When you buy a boxed Intel® processor, the package includes the CPU fan and heatsink assembly. If you buy a CPU separately, ensure that you use only Intel® certified multi directional heatsink and fan.
•Your Intel® LGA1156 heatsink and fan assembly comes in a push-pin design and requires no tool to install.
•Use an LGA1156-compatible CPU heatsink and fan assembly only. The LGA1156 socket is incompatible with the LGA775 and LGA1366 sockets in size and dimension.
If you purchased a separate CPU heatsink and fan assembly, ensure that you have properly applied Thermal Interface Material to the CPU heatsink or CPU before you install the heatsink and fan assembly.
Ensure that you have installed the motherboard to the chassis before you install the CPU fan and heatsink assembly.
To install the CPU heatsink and fan: |
A |
|||
1. |
Place the heatsink on top of the installed |
|||
B |
||||
|
CPU, ensuring that the four fasteners match |
|||
|
B |
|||
|
the holes on the motherboard. |
|||
|
|
|||
|
Orient the heatsink and fan assembly |
A |
||
|
such that the CPU fan cable is closest to |
|
||
|
the CPU fan connector. |
|
||
2. |
Push down two fasteners at a time in a |
|
||
|
diagonal sequence to secure the heatsink |

||
|
and fan assembly in place. |

The type of CPU heatsink and fan assembly may differ, but the installation steps and functions should remain the same. The illustration above is for reference only.
