Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To
protect them against damage from static electricity, you should follow some precautions whenever you
work on your computer.

1.Unplug your computer when working on the inside.
2.Use a grounded wrist strap before handling computer components. If you do not have
one, touch both of your hands to a safely grounded object or to a metal object, such as
the power supply case.
3.Hold components by the edges and try not touch the IC chips, leads or connectors, or
other components.
4.Place components on a grounded antistatic pad or on the bag that came with the
components whenever the components are separated from the system.
5.Ensure that the ATX power supply is switched off before you plug in or remove the ATX
ower connector on the motherboard.

Installing the motherboard to the chassis…
If the motherboard has mounting holes, but they don't line up with the holes on the base and there
are no slots to attach the spacers, do not become alarmed you can still attach the spacers to the
mounting holes. Just cut the bottom portion of the spacers (the spacer may be a little hard to cut off, so
be careful of your hands). In this way you can still attach the motherboard to the base without worrying
about short circuits. Sometimes you may need to use the plastic springs to isolate the screw from the
motherboard PCB surface, because the circuit wire may be near by the hole. Be careful, don't let the
screw contact any printed circuit write or parts on the PCB that are near the fixing hole, otherwise it may
damage the board or cause board malfunctioning.

Please set the CPU host frequency in accordance with your processor's specifications.
We don't recommend you to set the system bus frequency over the CPU's specification
because these specific bus frequencies are not the standard specifications for CPU,
chipset and most of the peripherals. Whether your system can run under these specific
bus frequencies properly will depend on your hardware configurations, including CPU,
Chipsets,SDRAM,Cards… .etc.

Chapter 2 Hardware Installation Process
To set up your computer, you must complete the following steps:
English
Step 1- Install the Central Processing Unit (CPU)
Step 2- Install memory modules

Step 1: Install the Central Processing Unit (CPU)
Before installing the processor, adhere to the following warning:
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.
Please make sure the CPU type is supported by the motherboard.
Step 1-1: CPU Installation

Step 1-2 : CPU Cooling Fan Installation
English
Before installing the CPU cool 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 cooling 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.
1. Fasten the cooling fan supporting-base
onto the CPU socket on the
mainboard.
2. Make sure the CPU fan is plugged to
the CPU fan connector, than install
complete.

Step 2: Install memory modules
Before installing the processor and heatsink, adhere to the following warning:
When DIMM_LED is ON, do not install/remove DIMM from socket.
Please note that the DIMM module can only fit in one direction due to the one notches.
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

slots to lock the DIMM module.
Reverse the installation steps when you wish
to remove the DIMM module.
DDR Introduction
Established on the existing SDRAM industry 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 sensible evolutionary solution for the PC industry that builds on the existing
SDRAM infrastructure, yet makes awesome advances in solving the system performance bottleneck by doubling the memory bandwidth. DDR SDRAM will offer a superior solution and migration
path from existing SDRAM designs due to its availability, pricing and overall market support. PC2100
DDR memory (DDR266) doubles the data rate through reading and writing at both the rising and
falling edge of the clock, achieving data bandwidth 2X greater than PC133 when running with the
same DRAM clock frequency. With peak bandwidth of 2.664GB per second, DDR memory enables
system OEMs to build high performance and low latency DRAM subsystems that are suitable for
servers, workstations, high-end PC's and value desktop SMA systems. With a core voltage of only
2.5 Volts compared to conventional SDRAM's 3.3 volts, DDR memory is a compelling solution for
small form factor desktops and notebook applications.

Step 3: Install expansion cards
1. Read the related expansion card's instruction document before install the expansion card into
the computer.
2. Remove your computer's chassis cover, necessary 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.
