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
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.

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.

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.
