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.  
M5A97 LE R2.0  
M5A97 LE R2.0 240-pin DDR3 DIMM sockets  
Recommended memory configurations  
1-9  
M5A97 LE R2.0  
 
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® 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.

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.

M5A97 LE R2.0  
Normal  
Clear RTC  
(Default)  
M5A97 LE R2.0 Clear RTC RAM  
To erase the RTC RAM:  
1.  
2.  
Turn OFF the computer and unplug the power cord.  
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.  
4.  
Plug the power cord and turn ON the computer.  
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.

Knowing BIOS  
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 keyboard-  
only 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.

(Advanced Host Controller Interface). The AHCI allows the onboard storage  
driver to enable advanced Serial ATA features that increases storage  
performance on random workloads by allowing the drive to internally optimize  
the order of commands.  
[RAID] Set to [RAID] when you want to create a RAID configuration from the SATA  
hard disk drives.  
SATA Port5 - Port6 [AHCI]  
[IDE] Set to [IDE] when you want to use the Serial ATA hard disk drives as Parallel

SATA connectors 1–6 in AHCI mode under the OS environment.  
If you use a SATA optical drive to run the Windows XP OS installation disk, we  
strongly recommend that you install the optical drive to the SATA connectors 5/6 and  
set them to [IDE] mode.

RAID support  
5
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.  
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 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.  
5-1  
ASUS M5A97 LE R2.0  
 
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.  
To install the SATA hard disks for a RAID configuration:  
1.  
2.  
3.  
Install the SATA hard disks into the drive bays.  
Connect the SATA signal cables.  
Connect a SATA power cable to the power connector on each drive.  
5.1.3

4.  
Enter the BIOS Setup during POST.  
Go to the Advanced menu > SATA Configuration, and then press <Enter>.  
Set the SATA Mode item to [RAID Mode].  
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 SATA ports are set to RAID mode, all SATA ports run at  
RAID mode together.
