•

Before connecting or removing signal cables from the motherboard,

ensure that all power cables are unplugged.

•

Seek professional assistance before using an adapter or extension cord.

These devices could interrupt the grounding circuit.

•

Make sure that your power supply is set to the correct voltage in your

area. If you are not sure about the voltage of the electrical outlet you are

using, contact your local power company.

•

If the power supply is broken, do not try to fix it by yourself. Contact a

qualified service technician or your retailer.

dynamically and automatically changes the CPU speed, voltage and amount

of power depending on the task the CPU performs. See pages 2-22, 3-31.

HyperTransport™ TechnologyHyperTransport™ Technology

HyperTransport™ Technology

HyperTransport™ Technology is a high-speed, low latency, point-to-point

link designed to increase the communication speed between integrated

circuits in computers, networking and telecommunicatons equipment up to

48 times faster than other existing technologies.

Dual Channel DDR memory supportDual Channel DDR memory support

Dual Channel DDR memory support

Employing the Double Data Rate (DDR) memory technology, the

motherboard supports up to 4GB of system memory using DDR400/333/

266 DIMMs. The ultra-fast 400MHz memory bus delivers the required

bandwidth for the latest 3D graphics, multimedia, and Internet applications.

1.2 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.

• Use a grounded wrist strap or touch a safely grounded object or to

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, ensureBefore you install or remove any component, ensure

Before you install the motherboard, study the configuration of your chassis

to ensure that the motherboard fits into it.

Make sure to unplug the power cord before installing or removing the

motherboard. Failure to do so can cause you physical injury and damage

motherboard components.

Do not overtighten the screws! Doing so can damage the motherboard.

1.4.1 OverviewOverview

OverviewOverview

Overview

The motherboard comes with a surface mount 939-pin Zero Insertion Force

(ZIF) socket designed for the AMD Athlon™ 64FX, AMD Athlon 64™ or AMD

Sempron™ processor.

The 128-bit-wide data paths of these processors can run applications

faster than processors with only 32-bit or 64-bit wide data paths.

Before installing the CPU, make sure that the socket box is facing

towards you and the load lever is on your left.

Take note of the marked corner (with

gold triangle) on the CPU. This mark

should match a specific corner on the

socket to ensure correct installation.
