New DIGI+ Power Control

All-New Digital Power Control for both CPU and DRAM

ASUS X79 motherboards include New DIGI+ Power Control with two digital voltage regulator modules (VRMs), including an all-new DRAM controller that allows ultra-precise memory tuning in addition to CPU voltage control. This evolution of innovative, industry-leading ASUS

technology provides super-accurate voltages for better efciency, stability and performance.

Best in class power efciency and stability Two critical components work perfectly together to match digital power signal (SVID) requests

from the CPU, with ultra-fast sensing and response to efciently deliver the right level of

power on demand. Accurate power reduces wasteful imprecision, and provides more stable CPU Vcore voltages.

Increased CPU and DRAM overclocking range With programmable digital controllers onboard, users can adjust CPU and DRAM PWM voltages and frequencies for various overclocking scenarios, with accurate input through UEFI BIOS tuning or the exclusive ASUS interface. System performance can also be

customized with specic CPU and DRAM power controls, including new VCCSA load line

calibration for increased voltage range, greater VCCSA current capability, and up to 30%

more capacitance. This proprietary design, with its precise yet exible power adjustments,

increases overclocking headroom to push performance to its full potential.

8+2 Phase Power Design

To fully unleash the latest Intel® Sandy Bridge-E CPU´s potential, this motherboard has

adopted a brand new digital 8-phase VRM power design. It delivers high power efciency and

supreme overclocking ability. Furthermore, high quality power components can effectively lower system temperature to ensure longer component lifespan. This motherboard also features an extra 2-phase power dedicated to integrated memory controller.

2.2.2 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.

Chapter 2

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.

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 congurations

Chapter 2

ASUS P9X79 PRO 2-5

Page 26

Memory congurations

You may install 1GB, 2GB, 4GB and 8GB unbuffered ECC and non-ECC DDR3 DIMMs into the DIMM sockets.

Chapter 2

• 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 dualchannel conguration. 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 specications 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 frequency adjustment.

• For system stability, use a more efcient 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.

• Visit the ASUS website for the latest QVL.

2.2.5 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. 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.

Chapter 2

2. Reset switch

Press the reset switch to reboot the system.

2-16 Chapter 2: Hardware information

Page 37

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

• 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.

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 ashed using standby power. Worry-free overclocking for the ultimate

convenience!

1 Download the BIOS Flashback program 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 ash (on the

third second).

4 The Flashback function is enabled once the light starts to ash.

5 The ashing 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 ashes for ve 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 le name or incompatibility in le 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.

2.4 Starting up for the rst time

1. After making all the connections, replace the system case cover.

2. Be sure that all switches are off.

3. Connect the power cord to the power connector at the back of the system chassis.

4. Connect the power cord to a power outlet that is equipped with a surge protector.

5. Turn on the devices in the following order:

a. Monitor

b. External SCSI devices (starting with the last device on the chain)

c. System power

6. After applying power, the system power LED on the system front panel case lights up. For systems with ATX power supplies, the system LED lights up when you press the ATX power button. If your monitor complies with the “green” standards or if it has a “power standby” feature, the monitor LED may light up or change from orange to green

Chapter 2

after the system LED turns on.

The system then runs the power-on self tests or POST. While the tests are running, the

BIOS beeps (refer to the BIOS beep codes table below) or additional messages appear on the screen. If you do not see anything within 30 seconds from the time you turned on the power, the system may have failed a power-on test. Check the jumper settings and connections or call your retailer for assistance.

BIOS Beep Description

One short beep VGA detected

One continuous beep followed by two short beeps then a pause (repeated) One continuous beep followed by three short beeps

One continuous beep followed by four short beeps

Quick boot set to disabled No keyboard detected No memory detected

No VGA detected

Hardware component failure

7. At power on, hold down the <Delete> key to enter the BIOS Setup. Follow the instructions in Chapter 3.

2.5 Turning off the computer

While the system is ON, pressing the power switch for less than four seconds puts the system on sleep mode or soft-off mode, depending on the BIOS setting. Pressing the power switch for more than four seconds lets the system enter the soft-off mode regardless of the BIOS setting.

Chapter 3: BIOS setup

3.1 Knowing BIOS

The new ASUS UEFI BIOS is an Unied Extensible Firmware Interface that complies with

UEFI architecture, offering a user-friendly interface that goes beyond traditional keyboard-

only BIOS controls to enable more exible 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 specied.

BIOS (Basic Input and Output System) stores system hardware settings such as storage

device conguration, overclocking settings, advanced power management, and boot device conguration 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 modication. 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 rst 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 sectionSee 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.
