Chapter 1
Product introduction
Thank you for buying an ASUS® P7H55-M LE Series motherboard!
Before you start installing the motherboard, and hardware devices on it, check the items in
your motherboard package. Refer to page ix for the list of accessories.
If any of the items is damaged or missing, contact your retailer.
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, switch off the ATX power supply and
detach its power cord. 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.

Central Processing Unit (CPU)
This 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.

System memory
1.4.1
Overview
DIMM_A1
DIMM_B1
This motherboard comes with two Double Data Rate 3 (DDR3) Dual Inline Memory Module
(DIMM) sockets.
A DDR3 module has the same physical dimensions as a DDR3 DIMM but is notched
differently to prevent installation on a DDR3 DIMM socket. DDR3 modules are developed
for better performance with less power consumption. The figure illustrates the location of the
DDR3 DIMM sockets:

Chapter 1: Product introduction
1.4.2
Memory configurations
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 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, it is
recommended that you obtain memory modules from the same vendor.
• Due to the memory address limitation on the 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 either of the
following:
-
-
Use a maximum of 3GB system memory if you are using a 32-bit Windows® OS.
Use a 64-bit Windows® OS if you want to install 4GB or more memory on the motherboard.
• This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.

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.
2.
3.
4.
5.
6.
Before installing the expansion card, read the documentation that comes with it and
make the necessary hardware settings for the card.
Remove the chassis cover (if your motherboard is already installed in a chassis).
Remove the bracket opposite the slot that you intend to use.
Align the card connector with the slot and press firmly until the card is completely
seated on the slot.
Secure the card to the chassis with the screw.
Replace the chassis cover.
1.5.2
Configuring an expansion card
After installing the expansion card, configure it by adjusting the software settings.
1.
2.
3.
Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for
information on BIOS setup.
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 slots
1.5.4
PCI Express x4 slot
1.5.5
PCI Express x16 slot
The PCI slots support cards such as LAN cards, SCSI cards, USB cards, and other cards
that comply with the PCI specifications.
This motherboard supports PCI Express x4 network cards, SCSI cards and other cards that
comply with the PCI Express specifications.
This motherboard supports PCI Express x16 graphics cards that comply 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.

Normal
(Default)
Clear RTC
P7H55-M LE
P7H55-M LE 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 reenter
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 cut off the AC power, then reboot the system, the BIOS automatically resets
parameter settings to default values.

• We recommend that you use an ATX 12V Specification 2.0‑compliant power supply unit
(PSU) with a minimum of 300W power rating. This PSU type has 24-pin and 4-pin power
plugs.
• If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the 20-pin
power plug can provide at least 15 A on +12 V and that the PSU has a minimum power
rating of 300 W. The system may become unstable or may not boot up if the power is
inadequate.
• DO NOT forget to connect the 4-pin ATX +12 V power plug; otherwise, the system will
not boot up.
• We recommend that you use a PSU with higher power output when configuring a
system with more power-consuming devices or when you intend to install additional
devices. The system may become unstable or may not boot up if the power is
inadequate.
• If you are uncertain about the minimum power supply requirement for your system,
refer to the Recommended Power Supply Wattage Calculator at http://support.asus.
