2.1 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.

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.

• 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.

Ensure that all power cables are unplugged before installing the CPU.

Recommended memory congurations

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.

2-6 Chapter 2: Hardware information

Chapter 2

Memory congurations

You may install 1GB, 2GB, 4GB and 8GB unbuffered 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 quad-

channel conguration. Any excess memory from the higher-sized channel is then

mapped for single-channel operation.

• Due to CPU behavior, DDR3 1800 MHz memory module will run at DDR3 1600 MHz

frequency as default.

• The Max. 64GB memory capacity can be supported with DIMMs of 8GB (or above).

ASUS will update QVL once the DIMMs are available on the market.

• 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.

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 efcient memory cooling system to support a full

memory load (4 DIMMs) or overclocking condition.

2.2.5 Jumper

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.

2.2.6 Onboard switch

The onboard switch allows 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.

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 2.2.7 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.

2.2.7 Onboard LEDs

1. Standby Power LED

The motherboard comes with a standby power LED. The green LED lights up to

indicate that the system is ON, in sleep mode, or in soft-off mode. This is a reminder

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 LED.

2. POST State LEDs

The POST State LEDs of CPU, DRAM, VGA card, and HDD indicate key components

status during POST (Power-on Self Test). If an error is found , the LED next to the

error device will continue lighting until the problem is solved. This user-friendly design

provides an intuitional way to locate the root problem within a second.

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

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 2.2.5 Jumper 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.

4.4 RAID congurations

The motherboard comes with the Intel® X79 chipset and Marvell SATA controller that allow

you to congure Serial ATA hard disk drives as RAID sets. The motherboard supports the

following RAID congurations:

• Intel® Rapid Storage Technology with RAID 0, RAID 1, RAID 10 and RAID 5 support.

• Marvell® 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 Service Pack 3 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 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.

ASUS SABERTOOTH X79 4-21

Chapter 4

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 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.

4.4.3 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. Enter the BIOS Setup during POST.

2. Go to the Advanced menu > SATA Conguration, and then press <Enter>.

3. Set the SATA Mode item to [RAID Mode].

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.
