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 theATX power supply is switched off before you plug in or remove theATX
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.

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 mightcause 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 byAMD.
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 3 dual DDR 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 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 DIMM
memory module can only fit in one direction.
2. Insert the DIMM memory module vertically 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.
DDR Introduction
Established on the existing SDRAM industry infrastructure, DDR (Double Date 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. PC1600 DDR memory (DDR200) doubles the data rate through reading and writing at
both the rising and falling edge of the clock, achieving data bandwidth 2X greater than PC100
when running with the same DRAM clock frequency. With peak bandwidth of 1.6GB 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.
