Installation Guide

Getting Started

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.

To set up your computer, you must complete the following steps:

Step 1 - Set system jumpers
Step 2- Install the Central Processing Unit (CPU)
Step 3-Install memory modules
Step 4-Install expansion cards
Step 5-Connect ribbon cables, cabinet wires, and power supply
Step 6-Set up BIOS software
Step 7-Install supporting software tools

CPU Installation

Please make sure the CPU should be supported to the motherboard.

CPU Top View

CPU Bottom View

1.Pull the lever out and lift it up.

2.The notched corner should be orientated
toward the blank space on the socket nearest
the lever. The CPU will only fit in the orientation
as shown.

CPU Heat Sink Installation:

Beware: Please check that the heat sink is in good contact with the CPU before you turn on your

system.

The poor contact will cause over heat, and might cause damage to your

processor!

3.Align CPU and insert it
(Please refer to your heatsink installation

manual for application of thermal grease to
provide better heat conduction between your
CPU and heatsink.)

4.Use compliant fan approved by AMD.

5.Hook one end of the cooler bracket to the CPU socket.

6. Hook the other end of the cooler bracket to the CPU socket.
(Please refer to the cooler’s installation manual for detailed installation steps)

Memory Installation

The motherboard has 2 dual inl ine memory mod ule (DIM M) sockets s upport 4 banks . 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 two notch.
Memory size can vary between sockets.

SDRAM

1. The DIMM slot has two notch, so the DIMM
memory module can only fit in one direction.

2. Insert the DIMM memory module verticall y
into the DIMM slot. Then push it down.

3. Close the plastic clip at both edges of the DIMM slots to lock the DIMM module.
Reverse the installation steps when you wish to remove the DIMM module.
