2.3.2 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®-certied
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.
Orient the heatsink and fan assembly such that the CPU fan cable is closest to the CPU fan
connector.
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.

2.4 System memory
2.4.1 Overview
The motherboard comes with four 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:
Recommended memory congurations
One DIMM:
Install one memory module in slot A1 or B1 rst as a single-channel operation.
Two DIMMs (dual-channel operation):
Four DIMMs (dual-channel operation):
ASUS P7P55D PRO 2-11
Chapter 2
2.4.2 Memory congurations
You may install 512MB, 1GB, 2GB and 4GB unbuffered and non-ECC DDR3 DIMMs into the
DIMM sockets.
• 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 3.5 Ai Tweaker menu for manual memory
frequency adjustment.
• For system stability, use a more efcient memory cooling system to support a full
memory load (4 DIMMs) or overclocking condition.
• 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 conguration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• Due to Intel spec denition, X.M.P. DIMMs and DDR3-1600 are supported for one
DIMM per channel only.
• 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. Prole feature in BIOS.
• 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).

2.5 Expansion slots
In the future, you may need to install expansion cards. The following subsections describe the
slots and the expansion cards that they support.
2.5.1 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. 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.
2.5.2 Conguring an expansion card
After installing the expansion card, congure it by adjusting the software settings.
1. Turn on the system and change the necessary BIOS settings, if any. See Chapter 3 for
information on BIOS setup.
2. Assign an IRQ to the card. Refer to the tables on the next page.
3. Install the software drivers for the expansion card.
Ensure to unplug the power cord before adding or removing expansion cards. Failure to do
so may cause you physical injury and damage motherboard components.
When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that
the cards do not need IRQ assignments. Otherwise, conicts will arise between the two PCI
groups, making the system unstable and the card inoperable. Refer to the table on the next
page for details.

2.6 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.
• Due to the chipset behavior, AC power off is required to enable C.P.R. function. You
must turn off and on the power supply or unplug and plug the power cord before
rebooting the system.

2.7 Onboard switches
Onboard switches allow you to ne-tune performance when working on a bare or open-case
system. This is ideal for overclockers and gamers who continually change settings to enhance
system performance.
1. MemOK! switch
Installing DIMMs that are incompaible 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.
• Refer to section 2.9 Onboard LEDs for the exact location of the DRAM_LED.
• 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.
• The MemOK! switch does not function under Windows® OS environment.
• 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.
• Due to memory tuning requirement, the system automatically reboots when each
timing set is tested. 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 (Qualied 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 unplug 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.
• We recommend that you download and update to the latest BIOS version from the
ASUS website at www.asus.com after using the MemOK! function.

2. DRAM overvoltage setting switch (OV_DRAM)
This switch allows you to enable or disable the advanced DRAM overvoltage settings in
BIOS. Read the following information before you change the switch settings.
• Before you change the settings for extra-high overvoltage ability, use the BIOS items
rst to adjust the desired DRAM performance. Ensure your system functions well
under the highest BIOS voltage settings before you change the setting of this switch.
• According to Intel CPU spec, DIMMs voltage below 1.65V is recommended to protect
the CPU.
• The system may need a better cooling system (for example, a water-cooling system)
to work stably under high voltage settings.

4.5 RAID congurations
The motherboard comes with the Intel® P55 chipset that allows you to congure Serial ATA
hard disk drives as RAID sets. The motherboard supports the following RAID congurations:
RAID 0, RAID 1, RAID 10 and RAID 5.
• You must install Windows® XP Service Pack 2 or later versions before using Serial
ATA hard disk drives. The Serial ATA RAID feature is available only if you are using
Windows® XP SP2 or later versions.
• Due to Windows® XP / Vista limitation, a RAID array with the total capacity over 2TB
cannot be set as a boot disk. A RAID array over 2TB can only be set as a data disk
only.
• If you want to install a Windows® operating system to a hard disk drive included in a
RAID set, you have to create a RAID driver disk and load the RAID driver during OS
installation. Refer to section 4.6 Creating a RAID driver disk for details.
4.5.1 RAID denitions
RAID 0 (Data striping) optimizes two identical hard disk drives to read and write data in
parallel, interleaved stacks. Two hard disks perform the same work as a single drive but at a
sustained data transfer rate, double that of a single disk alone, thus improving data access
and storage. Use of two new identical hard disk drives is required for this setup.
RAID 1 (Data mirroring) copies and maintains an identical image of data from one drive to
a second drive. If one drive fails, the disk array management software directs all applications
to the surviving drive as it contains a complete copy of the data in the other drive. This RAID
conguration provides data protection and increases fault tolerance to the entire system. Use
two new drives or use an existing drive and a new drive for this setup. The new drive must be
of the same size or larger than the existing drive.
RAID 5 stripes both data and parity information across three or more hard disk drives. Among
the advantages of RAID 5 conguration include better HDD performance, fault tolerance, and
higher storage capacity. The RAID 5 conguration is best suited for transaction processing,
relational database applications, enterprise resource planning, and other business systems.
Use a minimum of three identical hard disk drives for this setup.
RAID 10 is data striping and data mirroring combined without parity (redundancy data) having
to be calculated and written. With the RAID 10 conguration you get all the benets of both
RAID 0 and RAID 1 congurations. Use four new hard disk drives or use an existing drive
and three new drives for this setup.
Intel® Matrix Storage. The Intel® Matrix Storage technology supported by the ICH10R chip
allows you to create a RAID 0, RAID 1, RAID 5, and RAID 10 functions to improve both
system performance and data safety. You can also combine two RAID sets to get higher
performance, capacity, or fault tolerance provided by the difference RAID function. For
example, RAID 0 and RAID 1 set can be created by using only two identical hard disk drives.
4-14 Chapter 4: Software support
Chapter 4
4.5.2 Installing Serial ATA hard disks
The motherboard supports Serial ATA hard disk drives. For optimal performance, install
identical drives of the same model and capacity when creating a disk array.
To install the SATA hard disks for a RAID conguration:
1. Install the SATA hard disks into the drive bays.
2. Connect the SATA signal cables.
3. Connect a SATA power cable to the power connector on each drive.
4.5.3 Setting the RAID item in BIOS
You must enable the RAID function in the BIOS Setup before creating RAID set(s) using
SATA HDDs. To do this:
1. Enter the BIOS Setup during POST.
2. Go to the Main menu > Storage Conguration, and then press <Enter>.
3. Set the Congure SATA as item to [RAID].
4. Save your changes, and then exit the BIOS Setup.
Refer to Chapter 3 for details on entering and navigating through the BIOS Setup.
Due to chipset limitation, when set any of SATA ports to RAID mode, all SATA ports run at
RAID mode together.
