1.6 Before you proceed

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. Hold components by the edges to avoid touching the ICs on them.

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.

When lit, the green LED (SB_PWR1) 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.

The red LED (AGP_WARN1) is a smart protection from motherboard burn out
caused by an incorrect AGP card. If you plug in any 3.3V AGP card into the

1.5V AGP slot, this LED lights up thus preventing the system to power up. This

LED remains off if you plug in a 1.5V AGP card.

1.9 System memory

The motherboard comes with three Double Data Rate (DDR) Dual Inline Memory
Module (DIMM) sockets. These sockets support up to 2GB system memory using
184-pin unbuffered non-ECC PC2700/PC2100 (FSB533) or PC2100/PC1600
(FSB400) DDR DIMMs.

The following figure illustrates the location of the DDR DIMM sockets.

This motherboard supports different memory frequencies depending on the CPU
FSB (Front Side Bus) and the type of DDR DIMM.

CPU FSB DDR DIMM Type Memory Frequency

533 MHz PC2700 333 MHz

PC2100 266 MHz

400 MHz PC2100 266 MHz

PC1600 200 MHz

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

1.9.1 Memory configurations

You may install any DDR DIMMs with 64MB, 128MB, 256MB, 512MB, and 1GB
densities into the DIMM sockets.

Use only the following combinations to install DDR DIMMs. Otherwise, the
system may not boot up.

DDR DIMM1 DDR DIMM2 DDR DIMM3

(Rows 0&1) (Rows 2&3) (Rows 3&2)
SS/DS DS None

SS/DS SS SS

* SS - Single-sided DIMM

DS - Double-sided DIMM

1. DDR DIMM sockets 2 and 3 share the same rows, so if you install a
double-sided DIMM into DIMM2 socket, you must leave DIMM3 socket
empty.

2. You may install single-sided DIMMs into DIMM2 and DIMM3 sockets at the
same time but neither one can be x16 DDR module.

3. Double-sided x16 DDR DIMMs are not supported on this motherboard.

1.10 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.
NOTE: The AGP slot supports only 1.5V AGP cards.

2. Turn on the system and change the necessary BIOS settings, if any. See
Chapter 2 for BIOS information.

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.
