2. Central Processing Unit (CPU)

The motherboard comes with a surface mount 754-pin Zero Insertion Force
(ZIF) socket designed for the AMD Athlon™ 64 processor. Take note of the
marked corner (with gold triangle) on the CPU. This mark should match a
specific corner on the socket to ensure correct installation.

Incorrect installation of the CPU into the socket may bend the pins and
severely damage 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 PC3200/PC2700/PC2100/
PC1600 double-sided DDR DIMMs.

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

You can install 128 MB, 256 MB, 512 MB, and 1 GB DDR DIMMs into the
DIMM sockets using the memory configurations in this section.

A DDR DIMM is keyed with a notch so that it fits in only one direction.
DO NOT force a DIMM into a socket to avoid damaging the DIMM.

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

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 inoperable.

This motherboard has an Accelerated Graphics Port (AGP) slot that
supports +1.5V AGP 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.

Install only 1.5V AGP cards on this motherboard!

This jumper allows you to clear the Real Time Clock (RTC) RAM in
CMOS. You can clear the CMOS memory of date, time, and system
setup parameters by erasing the CMOS RTC RAM data. The onboard
button cell battery powers the RAM data in CMOS, which include
system setup information such as system passwords.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. Move the jumper cap from pins 2-3 (Normal) to pins 1-2 (Clear

CMOS). Keep the cap on pins 2-3 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 BIOS

setup to re-enter data.

Except when clearing the RTC RAM, never remove the cap from the
default position. Removing the cap will cause system boot failure!

These connectors are for Ultra DMA 100/66 signal cables. The Ultra

DMA 100/66 signal cable has three connectors: a blue connector for
the primary IDE connector on the motherboard, a black connector for
an Ultra DMA 100/66 IDE slave device (optical drive/hard disk drive),
and a gray connector for an Ultra DMA 100/66 IDE master device (hard
disk drive). If you install two hard disk drives, you must configure the
second drive as a slave device by setting its jumper accordingly. Refer
to the hard disk documentation for the jumper settings.

• Pin 20 on the IDE connector is removed to match the covered hole
on the Ultra DMA cable connector. This prevents incorrect insertion
when you connect the IDE cable.

• Use the 80-conductor IDE cable for Ultra DMA 100/66 IDE devices.

These connectors are for ATX power supply plugs. The power supply
plugs are designed to fit these connectors in only one orientation.
Find the proper orientation and push down firmly until the connectors
completely fit.

•

Do not forget to connect the 4-pin ATX +12 V power plug;
otherwise, the system will not boot up.

•

Make sure that your ATX 12V power supply can provide 8A on the
+12V lead and at least 1A on the +5-volt standby lead (+5VSB).
The minimum recommended wattage is 230W, or 300W for a fully
configured system. The system can become unstable and might
experience difficulty powering up if the power supply is inadequate.

• You must install a PSU with a higher power rating if you intend to
install additional devices.

The fan connectors support cooling fans of 350 mA ~ 2000 mA (24 W

max.) or a total of 1 A ~ 3.48 A (41.76 W max.) at +12V. Connect the
fan cables to the fan connectors on the motherboard, making sure that
the black wire of each cable matches the ground pin of the connector.

Do not forget to connect the fan cables to the fan connectors.
Insufficient air flow inside the system may damage the motherboard
components. These are not jumpers! Do not place jumper caps on the
fan connectors!
