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!

2. Unlock the socket by pressing
the lever sideways, then lift it up
to a 90°-100° angle.

Make sure that the socket
lever is lifted up to 90°-100°
angle, otherwise the CPU does
not fit in completely.

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.

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.
