Step 1: Install the Central Processing Unit (CPU)
Before installing the processor, adhere to the following warning:
English
1.Please make sure the CPU type is supported by the motherboard.
2.If you do not match the CPU socket Pin 1 and CPU cut edge well, it will
cause improper installation. Please change the insert orientation.

Step 1-2: CPU Cooling Fan Installation
Before installing the CPU cooling fan, adhere to the following warning:
1.Please use Intel approved cooling fan.
2.We recommend you to apply the thermal tape to provide better heat
conduction between your CPU and cooling fan.
(The CPU cooling fan might stick to the CPU due to the hardening of
the thermal paste. During this condition if you try to remove the cool-
ing fan, you might pull the processor out of the CPU socket alone with
the cooling fan, and might damage the processor. To avoid this from
happening, we suggest you to either use thermal tape instead of
thermal paste, or remove the cooling fan with extreme caution.)
3.Make sure the CPU fan power cable is plugged in to the CPU fan
connector, this completes the installation.
Please refer to CPU cooling fan user's manual for more detail
installation procedure.

Step 2: Install Memory Modules
Before installing the memory modules, adhere to the following warning:
1.When DIMM LED is ON, do not install / remove DIMM from socket.
English
2.Please note that the DIMM module can only fit in one direction due to
the one notch. Wrong orientation will cause improper installation.
Please change the insert orientation.
The motherboard has 2 dual inline memory module (DIMM) sockets. The BIOS will automatically
detects memory type and size. To install the memory module, just push it vertically into the DIMM
socket. The DIMM module can only fit in one direction due to the notch. Memory size can vary
between sockets.

1. The DIMM socket has a notch, so the DIMM
memory module can only fit in one direction.
2. Insert the DIMM memory module vertically into
the DIMM socket. Then push it down.
3. Close the plastic clip at both edges of the DIMM
sockets to lock the DIMM module.
Reverse the installation steps when you wish to
remove the DIMM module.
DDR Introduction
Established on the existing SDRAM infrastructure, DDR (Double Data Rate) memory is a high
performance and cost-effective solution that allows easy adoption for memory vendors, OEMs, and
system integrators.
DDR memory is a great evolutionary solution for the PC industry that builds on the existing
SDRAM architecture, yet make the awesome advances in solving the system performance bottleneck
by doubling the memory bandwidth. Nowadays, with the highest bandwidth of 3.2GB/s of DDR400
memory and complete line of DDR400/333/266/200 memory solutions, DDR memory is the best
choice for building high performance and low latency DRAM subsystem that are suitable for servers,
workstations, and full range of desktop PCs.

Step 3: Install expansion cards
1. Read the related expansion card's instruction document before install the expansion card into the
computer.
English
2. Remove your computer's chassis cover, screws and slot bracket from the computer.
3. Press the expansion card firmly into expansion slot in motherboard.
4. Be sure the metal contacts on the card are indeed seated in the slot.
5. Replace the screw to secure the slot bracket of the expansion card.
6. Replace your computer's chassis cover.
7. Power on the computer, if necessary, setup BIOS utility of expansion card from BIOS.
8. Install related driver from the operating system.
