Chapter 1
Product introduction
Thank you for buying an ASUS® P7H55/USB3 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, 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 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)
The motherboard comes with a surface mount LGA1156 socket designed for the Intel®
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.

1.3.2
Installing 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.

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:
Recommended memory configurations
One DIMM:
Install one memory module in slot A1 or B1 first as a single-channel operation.
Two DIMMs (dual-channel operation):
Four DIMMs (dual-channel operation):
1-8
Chapter 1: Product introduction
1.4.2
Memory configurations
You may install 1GB, 2GB and 4GB unbuffered and 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.
• According to Intel spec definition, DDR3-1600 is supported for one DIMM per channel
only. ASUS exclusively provides two DDR3-1600 DIMM support for each memory
channel.
• According to Intel CPU spec, DIMM voltage below 1.65V is recommended to protect the
CPU.
• According to Intel CPU spec, CPUs with a core frequency of 2.66G support the
maximum DIMM frequency of up to DDR3-1333. To use DIMMs of a higher frequency
with a 2.66G CPU, enable the DRAM O.C. Profile feature in BIOS. Refer to section 2.4
Ai Overclock Tuner for details.
• 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.
For more details, refer to the Microsoft® support site at
http://support.microsoft.com/kb/929605/en-us.
• This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less
(Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).
• 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 Ai Tweaker menu for manual memory frequency adjustment.
• For system stability, use a more efficient memory cooling system to support a full
memory load (4 DIMMs) or overclocking condition.

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.
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 the CMOS clearance, 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 C.P.R. (CPU Parameter Recall) feature. Shut
down and reboot the system so the BIOS can automatically reset parameter settings to
default values.

Onboard switches
Onboard switch allows you to fine-tune performance when working on a bare or opencase system. This is ideal for overclockers and gamers who continually change settings to
enhance system performance.
1.
MemOK! switch
Installing DIMMs that are incompatible with the motherboard may cause system
boot failure, and the DRAM_LED near the MemOK! switch lights continuously. Press
and hold the MemOK! switch until the DRAM_LED starts blinking to begin automatic
memory compatibility tuning for successful boot.
• The DRAM_LED also lights when the DIMM is not properly installed. Turn off the system
and reinstall the DIMM before using the MemOK! function.
• Press the MemOK! switch under Windows™ OS environment will reboot the computer
and start memory tuning.
• During the tuning process, the system loads and tests failsafe memory settings. It takes
about 30 seconds for the system to test one set of failsafe settings. If the test fails,
the system reboots and test the next set of failsafe settings. The blinking speed of the
DRAM_LED increases, indicating different test processes.
• If the installed DIMMs still fail to boot after the whole tuning process, the DRAM_LED
lights continuously. Replace the DIMMs with ones recommended in the Memory QVL
(Qualified Vendors Lists) in this user manual or on the ASUS website at
www.asus.com.
• If you turn off the computer and replace DIMMs during the tuning process, the system
continues memory tuning after turning on the computer. To stop memory tuning, turn off
the computer and unplog the power cord for about 5–10 seconds.
• If your system fail to boot due to BIOS overclocking, press the MemOK! switch to boot
and load BIOS default settings. A messgae will appear during POST reminding you that
the BIOS has been restored to its default settings.
