1.3.2
“Ultimate COOL!” Thermal Solution
TUF CeraM!X - Heatsink Coating Tech.
Chapter 1
Larger area for heat dissipation with the revolutionary ceramics-coating technology
Innovative ceramics actively conducts heat away from the system. It replaces traditional
anti-oxidant to dissipate heat better with its microscopic irregular surface and enlarged area.
Better cooling leads to overall improvement in system stability.
Do Not uninstall the heatsink module by youself. Doing so may bend the tubing and affect
the heat dissipation performance.
TUF Thermal Radar

The TUF Thermal Radar monitors temps in critical parts of the motherboard in real time,
automatically adjusting fan speeds to make sure the system maintains high stability without
overheating. It consists of multiple sensors for various components on the motherboard,
giving users the ability to monitor each one individually. The Thermal Radar automatically
calculates ideal fan speeds based on different parameters selected by users for each
component, keeping everything cooler and longer lasting.
1.3.3

Power eSATA on the Go
Chapter 1
The motherboard supports hard drives based on the Serial ATA (SATA) 3Gb/s storage
specification, delivering enhanced scalability and doubling the bus bandwidth for high-speed
data retrieval and saves.The Power eSATA solution combines the eSATA connector and
power source together, allowing users to use external SATA devices without the need of
additional power source*. The external SATA port located at the back I/O provides smart
setup and hot-plug functions. Easily backup photos, videos and other entertainment contents
on external devices. *Power eSATA requires a specially designed signal cable to provide 5V
power for the external SATA device. The cable is purchased separately.
IEEE 1394a interface
IEEE 1394a interface provides high speed digital interface for audio/video appliances such as
digital television, digital video camcorders, storage peripherals & other PC portable devices.
ErP Ready
The motherboard is European Union’s Energy-related Products (ErP) ready, and ErP requires
products to meet certain energy efficiency requirements in regards to energy consumptions.
This is in line with ASUS vision of creating environment-friendly and energy-efficient products
through product design and innovation to reduce carbon footprint of the product and thus
mitigate environmental impacts.

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 an AM3+ socket designed for AMD® FX Series CPU up to 8-core,
also compatible with AMD® socket AM3 for AMD® Phenom™ II/Athlon™ II/ Sempron™ 100
Series Processors.
Chapter 2
+
Ensure that all power cables are unplugged before installing the CPU.
The AM3+ socket has a different pinout designe, ensure that you use a CPU designed for
the AM3+/AM3 socket. The CPU fits in only one correct orientation. DO NOT force the CPU
into the socket to prevent bending the connectors on the socket and damaging the CPU!

Chapter 2: Hardware information
2.2.3
System memory
The motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules
(DIMM) slots.
Chapter 2
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 SABERTOOTH 990FX
2-5
Memory configurations
You may install 1GB, 2GB and 4GB unbuffered and non‑ECC DDR3 DIMMs into the DIMM
sockets.
Chapter 2
2-6
•
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 configuration. 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.
•
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 efficient memory cooling system to support a full
memory load (4 DIMMs) or overclocking condition.

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.
Chapter 2
To erase the RTC RAM
1.
Turn OFF the computer and unplug the power cord.
3.
Plug the power cord and turn ON the computer.
2.
4.
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.
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!
2-18
•
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.
Chapter 2: Hardware information
2.2.6
Onboard switch
The onboard switch allows you to fine-tune performance when working on a bare or opencase system. This is ideal for overclockers and gamers who continually change settings to
enhance system performance.
MemOK! switch
Chapter 2
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 (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.

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
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.

Knowing BIOS
BIOS setup
The new ASUS UEFI BIOS is an 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.
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.
•
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 2.2.5 Jumper for information
on how to erase the RTC RAM.
•
The BIOS setup program does not support the bluetooth devices.
Chapter 3
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 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 comes with the AMD® SB950 chipset that allows you to configure
Serial ATA hard disk drives as RAID sets. The motherboard supports the following RAID
configurations: RAID 0, RAID 1, RAID 10 and RAID 5.
4.4.1
•
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.
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.
Chapter 4
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.
ASUS SABERTOOTH 990FX
4-29
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.
Install the SATA hard disks into the drive bays.
3.
Connect a SATA power cable to the power connector on each drive.
2.
Connect the SATA signal cables.
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.
3.
Set the SATA Mode item to [RAID Mode].
2.
4.
Go to the Advanced menu > SATA Configuration, and then press <Enter>.
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.
