1.2.3 Central Processing Unit (CPU)

The motherboard comes with an AM3+/AM3 socket designed for AMD ® FX™ Series/

Phenom™ II/Athlon™ II/Sempron™ 100 Series Processors.

M5A97 LE R2.0

M5A97 LE R2.0 CPU socket AM3+

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

The AM3+ socket has a different pinout from the 940-pin socket designed for the AMD

Opteron processor. Ensure that you use a CPU designed for the 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!

1-8 Chapter 1: Product introduction

1.2.4 System memory

The motherboard comes with four 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.

Memory configurations

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

• Memory module with memory frequency higher than 2133 MHz and its corresponding timing or the loaded DRAM OC Profile is not the JEDEC memory standard. The stability and compatibility of these memory modules depend on the CPU’s capabilities and other installed devices.

• 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.

• 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 optimal compatibility, we recommend that you install memory modules of the same version or date code (D/C) from the same vendor. Check with the retailer to get the correct memory modules.

• 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: a) Use a maximum of 3GB system memory if you are using a 32-bit Windows OS.

b) Install a 64-bit Windows OS when you want to install 4GB or more on the motherboard.

c) For more details, refer to the Microsoft com/kb/929605/en-us.

® support site at http://support.microsoft.

• 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.

• Visit the ASUS website at www.asus.com for the latest QVL.

1.2.6 Jumpers

Clear RTC RAM (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.

1 2

CLRTC

2 3

M5A97 LE R2.0

Normal

(Default)

M5A97 LE R2.0 Clear RTC RAM

Clear RTC

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 reenter 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 clearing the CMOS, 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 CPU Parameter Recall (C.P.R) feature.

Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values.

The new ASUS UEFI BIOS is a Unified Extensible Interface that complies with UEFI architecture, offering a user-friendly interface that goes beyond the traditional keyboardonly BIOS controls to enable a more flexible and convenient mouse input. You can easily navigate the new UEFI BIOS with the same smoothness as your 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 optimal performance. DO 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 BIOS settings may result to instability or boot failure. We strongly recommend that you change the BIOS settings only with the help of a trained service

personnel.

RAID support

5.1 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 5 and RAID 10.

5

• You must install Windows

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

XP SP3 or later versions.

• Due to Windows ® XP 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 5.2 Creating a RAID driver disk for details.

5.1.1 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.

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 M5A97 LE R2.0

5-1

5.1.2 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.

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.

5.1.3 Setting the RAID item in BIOS

You must enable the RAID function in the BIOS Setup before creating RAID sets using SATA

HDDs. To do this:

1. Enter the BIOS Setup during POST.

2. Go to the Advanced menu > SATA Configuration, and then press <Enter>.

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

4. Save your changes, and then exit the BIOS Setup.
