Safety information
Electrical safety
• To prevent electrical shock hazard, disconnect the power cable from the
electrical outlet before relocating the system.
• When adding or removing devices to or from the system, ensure that the power
cables for the devices are unplugged before the signal cables are connected. If
possible, disconnect all power cables from the existing system before you add a
device.
• Before connecting or removing signal cables from the motherboard, ensure that
all power cables are unplugged.
• Seek professional assistance before using an adpater 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.
Operation safety
• Before installing the motherboard and adding devices on it, carefully read all the
manuals that came with the package.
• Before using the product, make sure all cables are correctly connected and the
power cables are not damaged. If you detect any damage, contact your dealer
immediately.
• To avoid short circuits, keep paper clips, screws, and staples away from
connectors, slots, sockets and circuitry.
• Avoid dust, humidity, and temperature extremes. Do not place the product in any
area where it may become wet.
• Place the product on a stable surface.
• If you encounter technical problems with the product, contact a qualified service
technician or your retailer.

1.6 Motherboard installation
The A7V8X-MX SE uses the Micro ATX form factor, measuring 24.5 cm (9.6 in.) x
24.5 cm (9.6 in.) - a standard fit for most Micro ATX chassis.
WARNING! Unplug the power cord before installing the motherboard. Failure to
do so may cause you physical injury and damage Motherboard components.
1.6.1 Placement direction
When installing the motherboard to the chassis, make sure to place it in the correct
orientation. The edge with external ports goes to the rear part of the chassis as
indicated in the image below. It may be more convenient to install major cables,
the CPU and modular components before fixing the motherboard inside the case
frame.
1.6.2 Screw holes
Place eight (8) screws into the holes indicated by circles to secure the
motherboard to the chassis.
Do not overtighten the screws! Doing so may damage the motherboard.
Place this side
towards the rear of
the chassis

Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component.
2. 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.
3. Avoid touching the ICs on components.
4. Whenever you uninstall any component, place it on a grounded antistatic
pad or in the bag that came with the component.
5. 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 A7V8X-MX SE motherboard comes with a standby power LED. When lit, this
green LED (SB_PWR) indicates that the system is ON, in sleep mode, or in soft-off
mode, a reminder that you should shut down the system and unplug the power cable
before removing or plugging in any motherboard component.

TO INNER
CORNER
LEVER
The motherboard provides a Socket A (462) for CPU installation. The A7V8X-MX
SE supports Athlon™ XP processors with “QuantiSpeed” data processing, large
data caches, 3D enhancements and 333/266/200MHz bus speeds. AMD Athlon™
XP processors offer gigahertz speeds to support all the latest computing platforms
and applications.
This motherboard does not support AMD processors with less than 1GHz core
speed.
Each AMD CPU has a “marked” corner. This corner is usually indicated with a
notch, and/or a golden square or triangle. Refer to this indicator while orienting
the CPU. A fan and heatsink should be attached to the CPU to prevent
overheating.
Installing the CPU
Follow these steps to install a CPU:
1. Locate the Socket 462 and open it by
pulling the lever gently sideways away
from the socket. Then lift the lever
upwards. The socket lever must be fully
opened (90 to 100 degrees).
2. Insert the CPU with the correct
orientation. The notched or golden
corner of the CPU must be oriented
toward the inner corner of the socket
base nearest to the lever hinge.
Golden corner

The CPU should drop easily into place. Do not force the CPU into the socket
to avoid bending the pins. If the CPU does not fit, check its alignment and look
for bent pins.

DIMM2
The motherboard has two Double Data Rate (DDR) DIMM sockets that supports
up to 2GB non-ECC PC2700/2100/1600 DDR SDRAM DIMMs. Each DIMM socket
is double-sided. DIMMs come in combinations of single or double-sided types
ranging through 64MB, 128MB, 256MB, 512MB, and 1 GB.
Installing a DIMM
1. Unlock a DIMM socket by pressing
the retaining clips outward.
2. Align a DIMM on the socket. Make
sure the notches on the DIMM
exactly match the notches in the
socket.
3. Firmly insert the DIMM into the
socket until the retaining clips lock
into place.
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.

1.10 Expansion slots
The A7V8X-MX SE motherboard has three (3) PCI slots and one (1) Accelerated
Graphics Port (AGP). The following sub-sections describe the slots and the
expansion cards that they support.
1.10.1 Configuring an expansion card
Some expansion cards need an IRQ to operate. Generally, an IRQ must be
exclusively assigned to one function at a time. In a standard design configuration,
16 IRQs are available but most are already in use.
Normally, 6 IRQs are free for expansion cards. Sometimes IRQs are “shared” by
more than one function; in this case, IRQ assignments are swapped automatically
or adjusted through the BIOS firmware.
