This section explains how to set jumpers for correct configuration of the moth-
erboard.
Setting Jumpers
Use the motherboard jumpers to set system configuration options. Jumpers
with more than one pin are numbered. When setting the jumpers, ensure that
the jumper caps are placed on the correct pins.
The illustrations below show a 2-pin jumper.
When the jumper cap is placed on both pins,
the jumper is SHORT. If you remove the
jumper cap, or place the jumper cap on just
one pin, the jumper is OPEN.

Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indica-
tion that data is being read from or written to the hard drive. For the LED to
function properly, an IDE drive should be connected to the onboard IDE inter-
face. The LED will also show activity for devices connected to the SCSI (hard
drive activity LED) connector.
Power / Sleep / Message Waiting LED
Connecting pins 2 and 4 to a single- or dual-color, front panel mounted LED
provides power on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pins 5 and 7 to a momen-
tary-contact switch that is normally open. When the switch is closed, the board
resets and runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a
momentary-contact switch that is normally open. The switch should maintain
contact for at least 50 ms to signal the power supply to switch on or off. The
time requirement is due to internal debounce circuitry. After receiving a power
on/off signal, at least two seconds elapses before the power supply recog-
nizes another on/off signal.

Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the motherboard or any of the surface-mount resis-
tors with the clip of the cooling fan. If the clip of the cooling fan scrapes
across the motherboard, you may cause serious damage to the mother-
board or its components.
On most motherboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-lit work area so that you can
clearly see the motherboard and processor socket.
Before installing the Processor
This motherboard automatically determines the CPU clock frequency and
system bus frequency for the processor. You may be able to change these
settings by making changes to jumpers on the motherboard, or changing the
settings in the system Setup Utility. We strongly recommend that you do not
overclock processors or other components to run faster than their rated speed.
Warning: Overclocking components can adversely affect the reliability of
the system and introduce errors into your system. Overclocking can per-
manently damage the motherboard by generating excess heat in
components that are run beyond the rated limits.
This motherboard has a Socket 462 processor socket. When choosing a
processor, consider the performance requirements of the system. Perform-
ance is based on the processor design, the clock speed and system bus
frequency of the processor, and the quantity of internal cache memory and
external cache memory.
13

CPU Installation Procedure
The following illustration shows CPU installation components:
Note: The pin-1 corner is marked with an arrow
Follow these instructions to install the CPU:
1. Pull the CPU socket locking lever away from the socket to unhook it and raise the
locking lever to the upright position.
2. Match the corner on the CPU marked with an arrow with pin A-1 on the CPU
socket (the corner with the pinhole noticeably missing). Insert the processor into
the socket. Do not use force.
3. Swing the locking lever down and hook it under the latch on the edge of the
socket.
4. Apply thermal grease to the top of the CPU.
5. Lower the CPU cooling fan/heatsink assembly onto the CPU
6. Secure the two retention clips
on either side of the
fan/heatsink unit onto the
Socket 462 base.

7. Connect the CPU Cooling Fan
power cable connector to the
CPUFAN connector.
Note: CPU fan and heatsink installation procedures may vary with the type of
CPU fan/heatsink supplied. The form and size of fan/heatsink may also
vary.
15

Installing Memory Modules
This motherboard accommodates two 184-pin 2.5V unbuffered Double Data
Rate (DDR) SDRAM memory modules. The memory chips must be standard
SDRAM (Synchronous Dynamic Random Access Memory). The memory bus
can run up to 133 MHz.
When you installed DDR266 memory modules, the memory bus can run up to
133 MHz. If you have DDR200, this can only run up to 100 MHz.
Note: SDRAM provides 800 MBps or 1 GBps data transfer depending on
whether the bus is 100MHz or 133MHz. Double Data Rate SDRAM
(DDR SDRAM) doubles the rate to 1.6 GBps and 2.1 GBps. DDR
SDRAM uses additional power and ground lines and requires 184-pin
DIMM modules rather than the 168-pin DIMMs used by SDRAM.
The motherboard accommodates two memory modules. You must install at
least one module in any of the two slots. Each module can be installed with 32
MB to 1 GB of memory; total memory capacity is 2GB.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the motherboard. Handle the modules only
by their edges. Do not touch the components or metal parts. Always
wear a grounding strap when you handle the modules.
Installation Procedure
Refer to the following to install the memory modules.
1. This motherboard supports unbuffered DDR SDRAM only. Do not attempt
to insert any other type of DDR SDRAM into the slots.
2. Push the latches on each side of the DIMM slot down.
3. Align the memory module with
the slot. The DIMM slots are
keyed with notches and the
DIMMs are keyed with cutouts
so that they can only be in-
stalled correctly.
4. Check that the cutouts on the
DIMM module edge connector
match the notches in the
DIMM slot.
