The AMD Athlon™ 64 is based on AMDʼs 64-bit architecture, which represents the landmark introduction of the industryʼs first x8664 technology. This processor provides a dramatic leap forward in compatibility, performance, investment protection, and reduced total cost of ownership and development.

The AMD Sempron™ is a 32-bit processor that provides the performance needs of value-conscious buyers. This processor is designed to deliver best-in-class performance for everyday computing. See page 1-9 for details.

1-2	Chapter 1: Product introduction

PCI Express™ interface

The motherboard fully supports PCI Express, the latest I/O interconnect technology that speeds up the PCI bus. PCI Express features point-to-point serial interconnections between devices and allows higher clock speeds by carrying data in packets. This high speed interface is software compatible with existing PCI specifications. See page 1-17 for details.

Serial ATA II technology

The motherboard supports the Serial ATA 3 Gb/s technology through the Serial ATA interfaces. The Serial ATA 3 Gb/s specification provides twice the bandwidth of the current Serial ATA products with a host of new features, including Native Command Queueing (NCQ), and Power

Management (PM) Implementation Algorithm. Serial ATA allows for thinner, more flexible cables with lower pin count, reduced voltage requirement. See page 1-24 for details.

The Hot Swap function is supported only in RAID mode.

S/PDIF digital sound ready

The motherboard supports the S/PDIF Out function through the S/PDIF interfaces on the rear panel and at midboard. The S/PDIF technology turns your computer into a high-end entertainment system with digital connectivity to powerful audio and speaker systems. See page 1-25 for details.

USB 2.0 technology

The motherboard implements the Universal Serial Bus (USB) 2.0 specification, dramatically increasing the connection speed from the

12 Mbps bandwidth on USB 1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is backward compatible with USB 1.1. See pages 1-19, 1-22 and 1-25 for details.

1.3.2Innovative ASUS features

ASUS EZ Flash BIOS

With the ASUS EZ Flash, you can easily update the system BIOS even before loading the operating system. No need to use a DOS-based utility or boot from a floppy disk. See page 2-3 for details.

ASUS CrashFree BIOS 2

This feature allows you to restore the original BIOS data from the support CD in case when the BIOS codes and data are corrupted. This protection eliminates the need to buy a replacement ROM chip. See page 2-6 for details.

ASUS MyLogo2™

This feature allows you to personalize and add style to your system with customizable boot logos. See page 2-35 for details.

C.P.R. (CPU Parameter Recall)

The C.P.R. feature of the motherboard BIOS allows automatic re-setting to the BIOS default settings in case the system hangs due to overclocking. When the system hangs due to overclocking, C.P.R. eliminates the need to open the system chassis and clear the RTC data. Simply shut down and reboot the system, and the BIOS automatically restores the CPU default setting for each parameter.

1-4	Chapter 1: Product introduction

1.4Before 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.

•Use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, before handling components 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, and/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.

1.7.3Installing a DIMM

Make sure to unplug the power supply before adding or removing DIMMs or other system components. Failure to do so may cause severe damage to both the motherboard and the components.

1.Unlock a DIMM socket by pressing the retaining clips outward.

2.Align a DIMM on the socket

such that the notch on the DIMM matches the break on the

socket. 1

2

DDR DIMM notch

A DDR DIMM is keyed with a notch so that it fits in only one direction. DO NOT force a DIMM into a socket to avoid damaging the DIMM.

3.Firmly insert the DIMM into the socket until the retaining clips snap back in place and the DIMM is properly seated.

1.7.4Removing a DIMM

To remove a DIMM:

1.Simultaneously press the retaining clips outward to unlock the DIMM.

1.8Expansion slots

In the future, you may need to install expansion cards. The following sub-sections describe the slots and the expansion cards that they support.

Make sure to unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components.

1.8.1Installing an expansion card

To install an expansion card:

1.Before installing the expansion card, read the documentation that came with it and make the necessary hardware settings for the card.

2.Remove the system unit cover (if your motherboard is already installed in a chassis).

3.Remove the bracket opposite the slot that you intend to use. Keep the screw for later use.

4.Align the card connector with the slot and press firmly until the card is completely seated on the slot.

5.Secure the card to the chassis with the screw you removed earlier.

6.Replace the system cover.

1.8.2Configuring an expansion card

After installing the expansion card, configure it by adjusting the software settings.

1.Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for information on BIOS setup.

2.Assign an IRQ to the card. Refer to the tables on the next page.

3.Install the software drivers for the expansion card.

IRQ assignments for this motherboard

	A	B	C	D
PCI slot 1	—	—	used	—
PCI slot 2	—	—	—	used

When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that the cards do not need IRQ assignments; otherwise, conflicts will arise between the two PCI groups, making the system unstable and the card inoperable.
