2. HARDWARE SETUP
2.1 Getting Started
IMPORTANT: Due to Pentium 4 CPU’s power consumption requirement, an
ATX12V power supply is recommended for this motherboard. For typical system
configurations, anATX12V power supply that can supply at least 230W and at least
8.5A on the +12V lead is required. For heavily-loaded configurations, an ATX12V
power supply that can supply at least 300W is required.
Before using your computer, you must complete the following steps:
• Check Motherboard Settings
• Install Memory Modules
• Install the Central Processing Unit (CPU)
• Install Expansion Cards
• Connect Ribbon Cables, Panel Wires, and Power Supply
WARNING! Computer motherboards and expansion cards contain very delicate
Integrated Circuit (IC) chips. To protect them against damage from static electric-
ity, you should follow some precautions whenever you work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do
nothave one, touch both of your hands to a safely grounded object or to a metal
object, such as the power supply case.
3. Hold components by the edges and try not to touch the IC chips, leads or con-
nectors, or other components.
4. Placecomponentson a grounded antistatic pad oronthebag that came with the
component whenever the components are separated from the system.
5. Ensure that the ATX power supply is switched off before you plug in or
remove the ATX power connector on the motherboard.
WARNING! Make sure that you unplug your power supply when adding or
removing system components. Failure to do so may cause severe damage to
your motherboard, peripherals, and/or components. The onboard LED when
lit acts as a reminder that the system is in suspend or soft-off mode and not
powered OFF.

2. HARDWARE SETUP
2.2 System Memory
NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard has four 184-pin Rambus Inline Memory Modules (RIMM) sockets.
These sockets support 64Mbit, 128Mbit, and 256Mbit Direct RDRAM technologies.
IMPORTANT
1. The memory configuration of channelA(RIMMA1 and RIMMA2) and chan-
nel B (RIMMB1 and RIMMB2) must be identical (see below).
2. C-RIMMs (Continuity RIMM) must be used to complete the sockets that are
not populated by RDRAMs. A C-RIMM is necessary to avoid breaking the
signal lines, which are a serial connection in a Rambus interface, such as
used in this motherboard. This assures the electrical integrity of a Rambus
interface.
3. When C-RIMMs are required, it is recommended that they be inserted into
RIMMA2 and RIMMB2.

2. HARDWARE SETUP
2.2.1 Installing Memory
The memory module (RIMM/C-RIMM) will fit in only one orientation.
IMPORTANT:Do not touch the memory module’s connectors. Handle the mod-
ule only by the edges.
1. Make sure that the notch keys in the module are aligned with the small ribs
inside the RIMM sockets.

RIBS (inside socket)
EJECTOR (TOP VIEW)
2. With the ejectors in the open position (as shown), push down gently but firmly
on the memory module until it snaps into place. The guides on the socket’s
ejectors should go through the two mounting notches on the module and the
ejectors should close. If necessary, push the ejectors inward to secure the mod-
ule in place.
Removing Memory
To release a memory module, push both ejectors outward and pull the module straight
up and out of the RIMM sockets.
WARNING! RIMM modules become extremely hot during operation. To re-
duce the risk of personal injury from hot surfaces, allow the modules to cool off
before removing them.

2.3 Central Processing Unit (CPU)
The motherboard provides a ZIF Socket for the P4 CPU. The CPU that came with
the motherboard should have a fan attached to it to prevent overheating. If this is not
the case, then purchase a fan before you turn on your system.

Before you start, you should check to see that you have the following items:
Rubber Pad Metal Baseboard
2 Metal heatsink retaining clips
4 Copper captive nuts
4 Pan Head screws
2 Heatsink support bases
4 Washers

2. HARDWARE SETUP
3.5.1 CPU Installation
Step 1: Install the Baseboard
A metal baseboard is required to install the heatsink to the motherboard. A rubber
pad is placed between the metal board and motherboard to provide insulation to
prevent shorting.
Placethefourwashersoverthe four
screws on the baseboard.

Washer
Tighten the four copper captive
nuts over the washers.
Rubber Pad Metal Baseboard
Align the rubber pad over
the metal baseboard so that
the holes match. Align the
motherboard over the rub-
ber pad and metal base-
board so that the screws on
the baseboard match up
with the motherboard’s
screw holes.
IMPORTANT:
This step is a MUST! The washers
are necessary to prevent shorting.

Step 2: Install the CPU
A. L ocate the Z I F socket on the motherboard.
B . Unlock the socket by pressing the lever sidesways and then lifting it up to a
90˚–100˚angle.
C . Align the C PU over the socket such that its notched or marked corner matches
the socket’s corner near the end of the lever, while making sure that the C PU is
parallel to the socket.
D . C arefully insert the C PU into the socket until it fits in place. The illustration
below shows how to insert a C PU properly.
CAUTION!The C PU fits in only one orientation. D o not force the C PU into the
socket as it will bend the pins and damage the C PU. I t should drop into the
socket with minimal pressure. I f not, check its orientation or check for bent pins.
E . Secure the C PU into the socket by pushing the socket lever all the way down.
Y ou will hear a click indicating that the lever is in place.
