Installing the CPU
Follow these steps to install a CPU.
1. Locate the 754-pin ZIF socket on the motherboard.
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. Position the CPU above the
socket such that the CPU corner
with the gold triangle matches
the socket corner with a small
triangle.
4. Carefully insert the CPU into the
socket until it fits in place.
5. When the CPU is in place, push
down the socket lever to secure
the CPU. The lever clicks on the
side tab to indicate that it is
locked.
6. Install a CPU heatsink and fan
following the instructions that
came with the heatsink package.
7. Connect the CPU fan cable to the
CPU_FAN connector on the
motherboard.

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.

Make sure to unplug the power supply before adding or removing DIMMs
or other system components. Failure to do so can 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 seated.

4. Expansion slots
The motherboard has one PCI Express and three PCI slots.
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
according to the card documentation.
