WARNING!
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
power 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.

and up to 90-degree angle.
3. Press down the CPU socket
lever and finish CPU installation.
Please make sure the CPU type is supported by the motherboard.
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.

CPU Heat Sink Installation
1. Hook one end of the cooler
bracket to the CPU socket first.
Please use Intel approved cooling fan.
We recommend you to apply the thermal tape to provide better heat
2. Hook the other end of the
cooler bracket to the CPU
socket.
conduction between your CPU and heatsink.
(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.)
Make sure the CPU fan power cable is plugged in to the CPU fan connector,
this completes the installation.
Please refer to CPU heat sink user’s manual for more detail installation
procedure.

Hardware Installation Process
Step 2: Install memory modules
The motherboard has 3 dual inline memory module (DIMM) sockets, but it can only support a maximum
of 4 banks of DDR memory. DDR slot 1 uses 2 banks, DDR slot 2&3 share the remaining 2 banks.
Please refer to the following tables for possible memory configurations supported. The BIOS will
automatically detects memory type and size. To install the memory module, just push it vertically into the
DIMM Slot .The DIMM module can only fit in one direction due to the notch. Memory size can vary
between sockets.

1. The DIMM slot has a notch, so the
DIMMmemory module can only fit in one direction.
2. Insert the DIMM memory module verticallyinto the
DIMM slot. Then push it down.
3. Close the plastic clip at both edges of theDIMM 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 2.1GB per second, DDR memory enables system OEMs to build
high performance and low latency DRAM subsystems that are suitable for servers, workstations, highend 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.
When STR/DIMM LED is ON, you do not install / remove DDR from socket.
Please note that the DIMM module can only fit in one direction due to
the two notches. Wrong orientation will cause improper installation.
Please change the insert orientation.

Hardware Installation Process
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, 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.
Please carefully pull out the small whitedrawable bar at the end of the AGP slot when
you try to install/ Uninstall the AGP card.
Please align the AGP card to the onboard
AGP Card
AGP slot and press firmly down on the slot .
Make sure your AGP card is locked by the
small white- drawable bar.
