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

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 pre-  
applied 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®-certified  
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.  
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  
CPU, ensuring that the four fasteners match  
the holes on the motherboard.

System memory  
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 figure illustrates the location of the DDR3 DIMM sockets:

1.4.2  
Memory configurations  
You may install 1GB, 2GB, 4GB and 8GB unbuffered non-ECC DDR3 DIMMs into the DIMM  
sockets.  
You may install varying memory sizes in Channel A and Channel B. The system maps  
the total size of the lower-sized channel for the dual-channel configuration. Any excess  
memory from the higher-sized channel is then mapped for single-channel operation.  
Always install DIMMs with the same CAS latency. For optimum compatibility, we  
recommend that you obtain memory modules from the same vendor.  
Due to the memory address limitation on 32-bit Windows® OS, when you install 4GB  
or more memory on the motherboard, the actual usable memory for the OS can be  
about 3GB or less. For effective use of memory, we recommend that you do any of the  
following:  
- Use a maximum of 3GB system memory if you are using a 32-bit Windows® OS.  
- Install a 64-bit Windows® OS when you want to install 4GB or more on the  
motherboard.  
This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less.  
The maximum 16GB memory capacity can be supported with 8GB or above DIMMs.  
ASUS will update the memory QVL once the DIMMs are available in the market.  
The default memory operation frequency is dependent on its Serial Presence Detect  
(SPD), which is the standard way of accessing information from a memory module.  
Under the default state, some memory modules for overclocking may operate at a  
lower frequency than the vendor-marked value. To operate at the vendor-marked or at a  
higher frequency, refer to section 2.4 Ai Tweaker menu for manual memory frequency  
adjustment.  
For system stability, use a more efficient memory cooling system to support a full  
memory load (2 DIMMs) or overclocking condition.

Expansion slots  
In the future, you may need to install expansion cards. The following sub-sections describe  
the slots and the expansion cards that they support.  
Unplug the power cord before adding or removing expansion cards. Failure to do so may  
cause you physical injury and damage motherboard components.  
1.5.1  
Installing an expansion card  
To install an expansion card:  
1.  
Before installing the expansion card, read the documentation that came with it and  
make the necessary hardware settings for the card.  
2.  
3.  
Remove the system unit cover (if your motherboard is already installed in a chassis).  
Remove the bracket opposite the slot that you intend to use. Keep the screw for later  
use.  
4.  
Align the card connector with the slot and press firmly until the card is completely  
seated on the slot.  
5.  
6.  
Secure the card to the chassis with the screw you removed earlier.  
Replace the system cover.  
1.5.2  
Configuring an expansion card  
After installing the expansion card, configure it by adjusting the software settings.  
1.  
Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for  
information on BIOS setup.  
2.  
3.  
Assign an IRQ to the card.  
Install the software drivers for the expansion card.  
When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that  
the cards do not need IRQ assignments. Otherwise, conflicts will arise between the two PCI  
groups, making the system unstable and the card inoperable.  
1.5.3  
PCI Express x1 slot  
This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that  
comply with the PCI Express specifications.  
1.5.4  
PCI Express x16 slot  
This motherboard has a PCI Express 2.0 x16 slot that supports PCI Express x16 2.0 graphic  
cards complying with the PCI Express specifications.

Jumpers  
Clear RTC RAM (3-pin CLRTC)  
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can  
clear the CMOS memory of date, time, and system setup parameters by erasing  
the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in  
CMOS, which include system setup information such as system passwords.

P8H61-M LX3  
Normal  
Clear RTC  
(Default)  
P8H61-M LX3 Clear RTC RAM  
To erase the RTC RAM:  
1. Turn OFF the computer and unplug the power cord.  
2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3  
for about 5-10 seconds, then move the cap back to pins 1-2.  
3. Plug the power cord and turn ON the computer.  
4. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter  
data.  
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default  
position. Removing the cap will cause system boot failure!  
If the steps above do not help, remove the onboard battery and move the jumper again  
to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.  
You do not need to clear the RTC when the system hangs due to overclocking. For  
system failure due to overclocking, use the CPU Parameter Recall (C.P.R.) feature. Shut  
down and reboot the system, then the BIOS automatically resets parameter settings to  
default values.
