Installing the CPU
Be very careful when handling the CPU. Make sure not to bend or break any pins on
the back. Hold the processor only by the edges and do not touch the bottom of the
processor.
Use the following procedure to install the CPU onto the motherboard.
1. Unhook the socket lever by pushing down
and away from the socket.
2. Lift the load plate. There is a protective
socket cover on the load plate to protect the
socket when there is no CPU installed.
3. Remove the protective socket cover from the
load plate.
4. Remove the processor from its protective
cover, making sure you hold it only by the
edges. It is a good idea to save the cover so
that whenever you remove the CPU, you
have a safe place to store it.
5. Align the notches in the processor with the
notches on the socket.
6. Lower the processor straight down into the
socket with out tilting or sliding it into the
socket.
Note: Make sure the CPU is fully seated and
level in the sock
7. Close the load plate over the CPU and press
down while you close and engage the socket
lever.
Installing the CPU Fan
There are many different fan types that can be
used with this motherboard. Follow the
instruction that came with you fan assembly. Be
sure that the fan orientation is correct for your
chassis type and your fan assembly.

Installing Memory
Use the following procedure to install memory DIMMs into the slots on the
motherboard. Note that there is only one gap near the center of the DIMM slot. This
slot matches the slot on the memory DIMM to ensure the component is installed
properly.
1. Unlock a DIMM slot by pressing the module clips outward.
2. Align the memory module to the DIMM slot, and insert the module vertically into
the DIMM slot. The plastic clips at both sides of the DIMM slot automatically lock
the DIMM into the connector.

Installing Chipset Fan
The motherboard come with an chipset fan.
Follow the step to install the chipset fan.
1) Place the fan on the angled side of the
chipset fan.
2) Match the pins on the to the slits on the
heatsink
3) Slide the fan down until the fan is clipped
on the heatsink

Power Connection
PWR1 is the main power supply connector located
along the edge of the board next to the DIMM
slots. Make sure that the power supply cable and
pins are properly aligned with the connector on the
motherboard. Firmly plug the power supply cable
into the connector and make sure it is secure.
PWR2, the 8-pin ATX 12V power connection, is
used to provide power to the CPU. Align the pins to
the connector and press rmly until seated.
