Central Processing Unit (CPU)  
The motherboard comes with a surface mount LGA2011 socket designed for the Intel®  
Core™ i7 Processor Extreme Edition/ Core™ i7 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  
LGA2011 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.

Chapter 2: Hardware information  
 
2.2.3  
System memory  
The motherboard comes with eight Double Data Rate 3 (DDR3) Dual Inline Memory Modules  
(DIMM) slots.  
A DDR3 module is notched differently from a DDR or DDR2 module. DO NOT install a DDR  
or DDR2 memory module to the DDR3 slot.  
Recommended memory configurations  
ASUS P9X79 PRO  
2-5  
 
Memory configurations  
You may install 1GB, 2GB, 4GB and 8GB unbuffered ECC and non-ECC DDR3 DIMMs into  
the DIMM sockets.  
You may install varying memory sizes in Channel A, Channel B, Channel C and  
Channel D. 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.  
Due to CPU behavior, DDR3 2200/2000/1800 MHz memory module will run at DDR3  
2133/1866/1600 MHz frequency as default.  
According to Intel CPU spec, 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 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. However, there are differences in memory support specifications on  
64-bit Windows OS.  
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 3.4 Ai Tweaker menu for manual memory  
frequency adjustment.  
For system stability, use a more efficient memory cooling system to support a full  
memory load (8 DIMMs) or overclocking condition.

DIMM support:  
2 DIMMs: Supports two (2) modules inserted into either the blue slots or the black  
slots as one pair of Dual-channel memory configuration. We suggest that  
you install the modules into slots B1 and D1 for better compatibility.  
4 DIMMs: Supports four (4) modules inserted into both the blue and black slots as  
two pairs of Dual-channel memory configuration.We suggest that you  
install the modules into slots A1/B1/C1/D1 for better compatibility.  
6 DIMMs: Supports six (6) modules inserted into both the blue and black slots as three  
pairs of Triple-channel memory configuration. We suggest that you install  
the modules into slots A1/B1/B2/C1/D1/D2 for better compatibility.  
8 DIMMs: Supports eight (8) modules inserted into both the blue and black slots as  
four pairs of Quad-channel memory configuration.  
When installing total memory of 4GB capacity or more, Windows 32-bit operation system  
may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is  
recommended.  
The default DIMM frequency depends 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  
ASUS exclusively provides hyper DIMM support function.  
Hyper DIMM support is subject to the physical characteristics of individual CPUs. Load  
the X.M.P. or D.O.C.P. settings in the BIOS for the hyper DIMM support.

Onboard switches  
Onboard switches allow you to fine-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.  
Power-on switch  
The motherboard comes with a power-on switch that allows you to power up or wake  
up the system. The switch also lights up when the system is plugged to a power source  
indicating that you should 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 power-on switch.  
2.  
Reset switch  
Press the reset switch to reboot the system.  
2-16  
Chapter 2: Hardware information  
 
3.  
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.  
Refer to section 2.2.6 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 (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 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.

USB BIOS Flashback  
USB BIOS Flashback offers the most convenient way to flash the BIOS. It allows overclockers  
to try new BIOS versions easily without having to enter their existing BIOS or operating  
system. Just plug in USB storage and push the dedicated button for 3 seconds, and the  
BIOS is automatically flashed using standby power. Worry-free overclocking for the ultimate  
convenience!  
1
Download the BIOS ROM file from the ASUS service website (www.asus.com). Rename  
it P9X79PRO.ROM, save the program to a USB portable disk, and place it in the root  
directory.  
2
On the rear I/O port, plug the USB disk to the USB port with the WHITE interior.  
3
Press the BIOS Flashback button for 3 seconds, and the light will begin to flash (on the  
third second).  
4
5
The Flashback function is enabled once the light starts to flash.  
The flashing rate of the light signal accelerates along with the updating speed.  
1. Do not unplug portable disk, power system, or press the CLR_CMOS button while  
BIOS update is ongoing, otherwise update will be interrupted. In case of interruption,  
please follow the recommended procedures again to complete BIOS update.  
2.  
If the light flashes for five seconds and turns into a stable lighting, this means that  
the BIOS Flashback is not operating properly. This may be caused by:1. Improper  
installation of the portable disk.2. Error in file name or incompatibility in file format.If  
this is the case, please restart the system to turn off the light.  
3. Updating BIOS may have risks. If the BIOS program is damaged during the process  
causing the system unable to reboot, please contact the local service station for help.

Chapter 3:  
BIOS setup  
3.1  
Knowing BIOS  
The new ASUS UEFI BIOS is an Unified Extensible Firmware Interface that complies with  
UEFI architecture, offering a user-friendly interface that goes beyond traditional keyboard-  
only BIOS controls to enable more flexible and convenient mouse input. Users can easily  
navigate the new UEFI BIOS with the same smoothness as their operating system. The  
term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specified.  
BIOS (Basic Input and Output System) stores system hardware settings such as storage  
device configuration, overclocking settings, advanced power management, and boot device  
configuration that are needed for system startup in the motherboard CMOS. In normal  
circumstances, the default BIOS settings apply to most conditions to ensure optimum  
performance. We recommend that you not change the default BIOS settings except in  
the following circumstances:  
An error message appears on the screen during the system bootup and requests you to  
run the BIOS Setup.  
You have installed a new system component that requires further BIOS settings or  
update.  
Inappropriate settings of the BIOS may result to instability or failure to boot. We strongly  
recommend that you change the BIOS settings only with the help of a trained service  
personnel.ç  
3.2  
BIOS setup program  
A BIOS setup program is provided for BIOS item modification. When you start up the  
computer, the system provides you with the opportunity to run this program. Press <Del>  
during the Power-On Self-Test (POST) to enter the Setup utility. Otherwise, POST continues  
with its test routines.  
If you wish to enter Setup after POST, press <Ctrl> + <Alt> + <Delete>, or press the reset  
button on the system chassis to restart the system. You can also turn the system off and then  
turn it back on to restart the system. Do this last option only if the first two failed.  
The BIOS setup screens shown in this section are for reference purposes only, and  
may not exactly match what you see on your screen.  
Ensure that a USB mouse is connected to your motherboard if you want to use the  
mouse to control the BIOS setup program.  
If the system becomes unstable after changing any BIOS setting, load the default  
settings to ensure system compatibility and stability. Select the Load Optimized  
Defaults item under the Exit menu. See section 3.9 Exit Menu for details.  
If the system fails to boot after changing any BIOS setting, try to clear the CMOS  
and reset the motherboard to the default value. See section 2.3.10 Rear Panel  
connection for information on how to erase the RTC RAM.  
The BIOS setup program does not support the bluetooth devices.  
The BIOS setup program is designed to make it as easy to use as possible. Being a  
menu-driven program, it lets you scroll through the various submenus and select from the  
available options using a keyboard or a USB mouse.  
The BIOS setup program can be used under two modes: EZ Mode and Advanced Mode.  
You can change modes from the Exit menu or from the Exit/Advanced Mode button in the  
EZ Mode/Advanced Mode screen.

RAID configurations  
The motherboard supports the following SATA RAID solutions:  
Intel® Rapid Storage Technology with RAID 0, RAID 1, RAID 10 and RAID 5 support.  
Mavell® RAID utility with RAID 0 and RAID 1 support.  
You must install Windows® XP Service Pack 3 or later versions before using Serial  
ATA hard disk drives. The Serial ATA RAID feature is available only if you are using  
Windows® XP SP3 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 4.5 Creating a RAID driver disk for details.  
4.4.1  
RAID definitions  
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  
configuration 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 configuration include better HDD performance, fault tolerance, and  
higher storage capacity. The RAID 5 configuration 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 configuration you get all the benefits of both  
RAID 0 and RAID 1 configurations. Use four new hard disk drives or use an existing drive  
and three new drives for this setup.

4.4.2  
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 configuration:  
1.  
2.  
3.  
Install the SATA hard disks into the drive bays.  
Connect the SATA signal cables.  
Connect a SATA power cable to the power connector on each drive.  
4.4.3  
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.  
2.  
3.  
4.  
Enter the BIOS Setup during POST.  
Go to the Advanced menu > SATA Configuration, and then press <Enter>.  
Set the SATA Mode item to [RAID Mode].  
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.
