Before 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 should 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.

2.3Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA1156 socket designed for the Intel® Core™ i7 / Core™ i5 / Core™ i3 / Pentium® processors.
Ensure that all power cables are unplugged 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.
2.3.1Installing the CPU
To install a CPU:
1.Locate the CPU socket on the motherboard.
Chapter 2
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.

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 |

2.3.2Installing 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 the Thermal Interface Material is properly applied 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:
1. |
Place the heatsink on top of the installed |
A |
|
|
CPU, ensuring that the four fasteners |
B |
|
|
match the holes on the motherboard. |

3.Connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN.
DO NOT forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector.
2.3.3Uninstalling the CPU heatsink and fan
To uninstall the CPU heatsink and fan:
1. |
Disconnect the CPU fan cable from the |
A |
|
|
connector on the motherboard. |

2. |
Rotate each fastener counterclockwise. |

2.4System memory
2.4.1Overview
The motherboard comes with four Double Data Rate 3 (DDR3) Dual In-line Memory Modules (DIMM) sockets.
A DDR3 module has the same physical dimensions as a DDR2 DIMM but is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are developed for better performance with less power consumption.
The figure illustrates the location of the DDR3 DIMM sockets:
