2 ASUS A7V8X-LA motherboard
2. Central Processing Unit (CPU)
The motherboard comes with a Socket A (462) for the AMD processor. AMD
processors offer gigahertz speeds to support all latest computing platforms and
applications. The A7V8X-LA supports AMD Athlon™/Athlon XP™ 3200+
processors. This motherboard also supports 400/333/266MHz front side bus
(FSB), and allows data transfers of up to 2.7 GB/s with PC2700 DDR.
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 a 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.
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!

3. System memory
The motherboard comes with two Double Data Rate (DDR) Dual Inline Memory
Module (DIMM) sockets. These sockets support up to 2 GB system memory using
184-pin unbuffered non-ECC PC/2700/PC2100/PC1600 double-sided DDR
DIMMs.
The following figure illustrates the location of the DDR DIMM sockets.
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.
Follow these steps to install a DIMM.
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.
3. Firmly insert the DIMM into the
socket until the retaining clips
snap back in place and the DIMM
is properly seated.
Installing a DIMM
You may install 64MB, 128MB, 256MB, 512MB, 1GB DDR DIMMs into the DIMM
sockets using the memory configurations in this section.

CAUTION: DIMMs are keyed to fit with only one direction. DO NOT force a
DIMM into a socket to avoid damaging the DIMM.

4. Expansion slots
The motherboard has three PCI slots and one Accelerated Graphics Port (AGP) slot.
To install and configure an expansion card:
1. Install an expansion card following the instructions that came with the chassis.
2. Turn on the system and change the necessary BIOS settings, if any.
3. Assign an IRQ to the card. Refer to the tables below.
4. Install the drivers and/or software applications for the expansion card
according to the card documentation.

Install only +1.5V AGP cards on this motherboard!
PCI slots
There are three (3) 32-bit PCI slots on this motherboard. The slots support PCI
cards such as a LAN card, SCSI card, USB card, and other cards that comply with
PCI specifications. The figure below shows a typical PCI card installed into a slot.
AGP slot
This motherboard has an Accelerated Graphics Port (AGP) slot that supports
AGP 8X/4X cards. When you buy an AGP card, make sure that you ask for one
with +1.5V specification.
Note the notches on the card golden fingers to ensure that they fit the AGP slot on
your motherboard.

5. Jumpers
1. Clear CMOS (3-pin CLRTC)
This jumper allows you to clear the RAM data in CMOS, except the system
date and time. The RAM data in CMOS, is powered by the onboard button cell
battery.
To erase the CMOS RAM:
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 2-3 (Default) to pins 1-2 (Clear CMOS).
Keep the cap on pins 1-2 for about 5~10 seconds, then move the cap back
to pins 2-3.
3. Plug the power cord and turn ON the computer.
4. Hold down the <F1> key during the boot process and enter the BIOS setup
to re-enter data.
Except when clearing the CMOS RAM, never remove the jumper cap on CLRTC
jumper default position. Removing the cap will cause system boot failure!
