This chapter lists the hardware setup
procedures that you have to perform
when installing system components.
It includes description of the jumpers
and connectors on the motherboard.
Hardware
information
1.1 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.
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 LEDs
The motherboard comes with a green 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 red warning LED lights up when you installed two graphics cards
but did not connect the ASUS EZ Plug™. The illustration below shows
the location of the onboard LEDs.

Chapter 1: Hardware information
1.2 Motherboard overview
Before you install the motherboard, study the configuration of your chassis
to ensure that the motherboard fits into it. Refer to the chassis
documentation before installing the motherboard.
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.
1.2.1 Placement direction
When installing the motherboard, make sure that you place it into the
chassis in the correct orientation. The edge with external ports goes to the
rear part of the chassis as indicated in the image below.
1.2.2 Screw holes
Place nine screws into the holes indicated by circles to secure the
motherboard to the chassis.
Do not overtighten the screws! Doing so can damage the motherboard.
Place this side towards
the rear of the chassis

1.3 Central Processing Unit (CPU)
The motherboard comes with a surface mount 939-pin Zero Insertion Force
(ZIF) socket designed for the AMD Athlon™ 64FX or AMD Athlon™ 64
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.
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.
Gold triangle
1.3.1 Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.

2. Unlock the socket by pressing
the lever sideways, then lift it up
to a 90°-100° angle.
Socket lever
Make sure that the socket lever is lifted up to 90°-100° angle; otherwise
the CPU does not fit in completely.
3. Position the CPU above the
socket such that the CPU corner
with the gold triangle matches
the socket corner with a small
triangle.
4. Carefully insert the CPU into the
socket until it fits in place.
Gold
triangle
Small triangle
The CPU fits only in one correct orientation. DO NOT force the CPU into
the socket to prevent bending the pins and damaging the CPU!
5. When the CPU is in place, push
down the socket lever to secure
the CPU. The lever clicks on the
side tab to indicate that it is
locked.
