Chapter 2: Hardware information
2.4.2 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.
CAUTION! 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.
4. Once completely inserted, press the CPU firmly and close the socket
lever until it snaps shut.
5. Place the CPU fan and heatsink on the CPU. The heatsink should entirely
cover the CPU. Carefully attach the heatsink locking brace to the plastic
clips on the socket base. With the added weight of the CPU fan and
heatsink locking brace, no extra force is required to keep the CPU in
place
CAUTION! Take care not to scrape the motherboard surface when
mounting a clamp-style processor fan, or else damage may occur . When
mounting a heatsink onto your CPU, make sure that exposed CPU
capacitors do not touch the heatsink, or damage may occur!
NOTE! Do not neglect to set the correct Bus Frequency and leave the
CPU Multiple setting at default to avoid start-up problems.

2.5 System memory
2.5.1 Overview
This motherboard uses only Double Data Rate (DDR) Synchronous Dynamic
Random Access Memory (SDRAM) Dual Inline Memory Modules (DIMMs).
These sockets support up to 3GB system memory using non-ECC 200/266/
333MHz DIMMs.
Each DIMM socket/module is two-sided: each side defines one “row” of
memory. DIMMs come in combinations of single or double-sided types
ranging through 64MB, 128MB, 256MB, 512MB and 1GB to form a total
memory size of 64MB to 3GB.
~ Three (3) sockets are available for both 333MHz-PC2700, 266MHz-PC2100
or 200MHz-PC1600 DDR DIMMs to form a memory size of 64MB to 3GB.

CAUTION! DIMMs are keyed to fit into notches with only one direction.
DO NOT force a DIMM into a socket to avoid damaging the DIMM.
• DIMMs with more than 18 chips are not supported.
• ASUS motherboards support SPD (Serial Presence Detect)DIMMs.
This is the memory of choice for best performance vs. stability
• BIOS shows DDR SDRAM memory on bootup screen.
• This motherboard supports three pairs of differential clock signals
per DIMM.
• For best performance, always use the “Performance” or “OEM”
grade of RAM.

2.6 Expansion slots
The motherboard has five PCI slot and one Accelerated Graphics Port (AGP)
slot.. The following sub-sections describe the slots and the expansion cards
that they support.
WARNING! Unplug your power supply when adding or removing
expansion cards or other system components. Failure to do so may cause
you physical injury and damage motherboard components.
2.6.1 Installing an expansion card
Follow these steps to install an expansion
card.
1. Before installing the expansion card, read
the documentation that came with it and
make the necessary hardware settings.
2. Remove the system unit cover (if your
motherboard is already installed in a
chassis).
3. Remove the bracket opposite the PCI slot.
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.
7. Set up the BIOS if necessary.
8. Install the necessary software drivers for your expansion card.
2.6.2 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. If the motherboard has PCI audio
onboard, an additional IRQ will be used. If your motherboard also has MIDI
enabled, another IRQ will be used, leaving 4 IRQs free. Sometimes IRQs
are “shared” by more than one function; in this case, IRQ assignments are
swapped automatically or adjusted through the BIOS firmware.
16
Chapter 2: Hardware information
IMPORTANT! 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 inoperative.
