Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
2. Central Processing Unit (CPU)
Before installing the CPU, make sure that the socket box is facing
towards you and the load lever is on your left.

2.1 OverviewOverview
OverviewOverview
Overview
The motherboard comes with a surface mount
754-pin Zero Insertion Force (ZIF) socket
designed for the AMD Athlon™ 64/AMD
Sempron™ 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.
2. Unlock the socket by pressing
the lever sideways, then lift it up
to a 90°-100°angle. SocketSocket

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.

Important notes on memory configurations
• Installing DDR DIMMs other than the recommended configurations
may cause memory sizing error or system boot failure. Use any of
the recommended configurations on the next page.
• Install only identicalidentical
identicalidentical
identical (the same type and size) DDR DIMM pairs
using the recommended configurations.
• Make sure that the memory frequency matches the CPU FSB
(Front Side Bus). Refer to the Memory frequency/CPU FSB
synchronization table on the next page.
• This motherboard does not support double-sided 16-bit DDR DIMMs.
• Do not create a three-DIMM configuration in dual-channel mode. The
third DIMM is ignored in the dual-channel operation.
The motherboard comes with four Double Data Rate (DDR) Dual Inline
Memory Module (DIMM) sockets.
The following figure illustrates the location of the DDR DIMM sockets.

Removing a DDR DIMM
To remove a DIMM:
1. Simultaneously press the
retaining clips outward to unlock
the DIMM.
2. Remove the DIMM from the socket.
Support the DIMM lightly with your fingers when pressing the retaining
clips. The DIMM might get damaged when it flips out with extra force.

3. Firmly insert the DIMM into the
socket until the retaining clips
snap back in place and the DIMM
is properly seated.
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.

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.
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.
