P8H61-M LE/USB3 CPU socket LGA1155
The motherboard comes with a surface mount LGA1155 socket designed for the Intel®
Second Generation Core™ i7 / Core™ i5 / Core™ i3 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.
1.6.1 Installing 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.

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

1.6.2 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
• Use an LGA1155-compatible CPU heatsink and fan assembly only. The LGA1155 socket
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.
®
LGA1155 heatsink and fan assembly comes in a push-pin design and
requires no tool to install.
is incompatible with the LGA775 and LGA1366 sockets in size and dimension.
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.
Orient the heatsink and fan assembly
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.

1.7 System memory
1.7.1 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:
Channel Sockets
Channel A DIMM_A1
Channel B DIMM_B1
ASUS P8H61-M LE Series1-14
1.7.2 Memory congurations
You may install 512MB, 1GB, 2GB, and 4GB 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 conguration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• According to Intel CPU specication, DIMM voltage below 1.65V is recommended to
protect the CPU.
• 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
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
- 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 efcient memory cooling system to support a full
memory load (2 DIMMs) or overclocking condition.

1.8 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.
1.8.1 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. Remove the system unit cover (if your motherboard is already installed in a chassis).
3. 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 rmly until the card is completely
seated on the slot.
5. Secure the card to the chassis with the screw you removed earlier.
6. Replace the system cover.
1.8.2 Conguring an expansion card
After installing the expansion card, congure 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. Assign an IRQ to the card.
3. 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, conicts will arise between the two PCI
groups, making the system unstable and the card inoperable.
1.8.3 PCI slot
The PCI slot supports cards such as a LAN card, SCSI card, USB card, and other cards that
comply with PCI specications.
1.8.4 PCI Express x1 slot
This motherboard supports PCI Express 2.0 x1 network cards, SCSI cards, and other cards
that comply with the PCI Express specications.
1.8.5 PCI Express x16 slot
This motherboard has a PCI Express 2.0 x16 slot that supports PCI Express 2.0 x16 graphic

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.
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 <
data.
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default
position. Removing the cap will cause system boot failure!
Del> key during the boot process and enter BIOS setup to re-enter
• 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.
