Product introduction
If any of the items is damaged or missing, contact your retailer.
Thank you for buying an ASUS® P8H61-I LX motherboard!
Before you start installing the motherboard, and hardware devices on it, check the items in
your motherboard package. Refer to page x for the list of accessories.
1.1 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
This 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.

1.2 Motherboard overview
Before you install the motherboard, study the conguration of your chassis to ensure that the
motherboard ts 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.
1.2.1 Placement 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.
1.2.2 Screw holes
Place four 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

1.3 Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA1155 socket designed for the Intel®
Second Generation 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
LGA1155 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.
1.3.1 Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
To prevent damage to the socket pins,
do not remove the PnP cap unless
you are installing a CPU.
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.

8. Insert the load lever under the retention
tab.
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.

1.3.2 Installing the CPU heatsink and fan
The Intel® LGA1155 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®-certied
multi-directional heatsink and fan.
• Your Intel® LGA1155 heatsink and fan assembly comes in a push-pin design and
requires no tool to install.
• Use an LGA1155-compatible CPU heatsink and fan assembly only. The LGA1155 socket
is incompatible with the LGA775 and LGA1366 sockets in size and dimension.
Ensure that you have installed the motherboard to the chassis before you install the CPU
fan and heatsink assembly.
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.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the installed
CPU, ensuring that the four fasteners match
the holes on the motherboard.

2. Push down two fasteners at a time in a
diagonal sequence to secure the heatsink
and fan assembly in place.
Orient the heatsink and fan assembly
such that the CPU fan cable is closest to
the CPU fan connector.
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.
E6873_P8H61-I LX.indb 7 2/15/12 6:37:04 PM
ASUS P8H61-I LX1-8
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.
1.3.3 Uninstalling the CPU heatsink and fan
To uninstall the CPU heatsink and fan:
1. Disconnect the CPU fan cable from the connector on the motherboard.
2. Rotate each fastener counterclockwise.
3. Pull up two fasteners at a time in a diagonal sequence to disengage the heatsink and
fan assembly from the motherboard.

1.4.1 Overview
The motherboard comes with two Double Data Rate 3 (DDR3) Dual Inline 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 gure illustrates the location of the DDR3 DIMM sockets:
4. Carefully remove the heatsink and fan
assembly from the motherboard.
