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.
Onboard LED
The motherboard comes with a standby power LED that 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.

2.3 Central Processing Unit (CPU)

The motherboard comes with an AMD® AM3 socket for AMD® Phenom™ II / Athlon™ II / Sempron™ 100 series processors.
The AM3 socket has a different pinout from the AM2+/AM2 socket. Make sure you use
a CPU designed for the AM3 socket. The CPU ts 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!

2.3.1 Installing the CPU

To install a CPU:
1. Locate the CPU socket on the motherboard.
Chapter 2
2. Press the lever sideways to unlock the
socket, then lift it up to a 90˚ angle.
Make sure that the socket lever is lifted
up to a 90˚ angle. Otherwise, the CPU will not t in completely.

6. Apply some Thermal Interface Material to the exposed area of the CPU that the heatsink will be in contact with, ensuring that it is spread in an even thin layer.
Some heatsinks come with pre-applied thermal paste. If so, skip this step.
The Thermal Interface Material is toxic and inedible. DO NOT eat it. If it gets into your eyes or touches your skin, wash it off immediately, and seek professional medical help.
To prevent contaminating the paste, DO NOT spread the paste with your nger.
2-6 Chapter 2: Hardware information

2.3.2 Installing the CPU heatsink and fan

The AMD® AM3 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance.
The retention module base is already installed on the motherboard upon purchase.
You do not have to remove the retention module base when installing the CPU or installing other motherboard components.
Ensure that you use only AMD-certied heatsink and fan assembly.
If you purchased a separate CPU heatsink and fan assembly, ensure that the Thermal Interface Material is properly applied to the CPU heatsink or CPU before you install the heatsink and fan assembly.
Ensure that you have installed the motherboard to the chassis before you install the CPU fan and heatsink assembly.
To install the CPU heatsink and fan
1. Place the heatsink on top of the installed CPU, ensuring that the heatsink ts properly
on the retention module base.

2.4 System memory

2.4.1 Overview

The motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules (DIMM) sockets.
A DDR3 module has the same physical dimensions as a DDR2 DIMM but is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are developed for better performance with less power consumption.
The gure illustrates the location of the DDR3 DIMM sockets:
Chapter 2
Recommended memory congurations
One DIMM:
You may install one memory module in any slot as a single-channel operation.
Two DIMMs (dual-channel operation):
Four DIMMs (dual-channel operation):
2-10 Chapter 2: Hardware information
2.4.2 Memory congurations
You may install 512MB, 1GB, 2GB and 4GB unbuffered ECC and non-ECC DDR3 DIMMs into the DIMM sockets.
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 conguration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.
We recommend that you install the memory modules from the blue slots for better overclocking capability.
Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended 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 256 Mb (32MB) 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 3.5 Advanced 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.

2.6 Jumpers

1. 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.
Chapter 2
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.

3.1 Knowing BIOS

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.

3.2 Updating BIOS

The ASUS website publishes the latest BIOS versions to provide enhancements on system stability, compatibility, or performance. However, BIOS updating is potentially risky. If there is no problem using the current version of BIOS, DO NOT manually update the BIOS. Inappropriate BIOS updating may result in the system’s failure to boot. Carefully follow the instructions of this chapter to update your BIOS if necessary.

4.4 RAID congurations
The motherboard comes with the AMD SB750 chipset that allows you to congure Serial
ATA hard disk drives as RAID volumes. The motherboard supports the following RAID
congurations: RAID 0, RAID 1, RAID 5, and RAID 10.
You must install Windows® XP Service Pack 2 or later versions before using Serial ATA hard disk drives. The Serial ATA RAID feature is available only if you are using Windows® XP SP2 or later versions.
Due to Windows 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 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)
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)
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 0+1 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.
