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.

7

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

Socket Actuation Lever

1. Pull up the CPU socket lever
and up to 90-degree angle.

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!

2. Locate Pin 1 in the socket and look
for a (golden) cut edge on the CPU
upper corner. Then insert the CPU
into the socket.

7DXE Motherboard

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.)

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)

4.Use compliant fan approved by AMD.

Memory Installation

The motherboard has 3 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 Slot .The DIMM module can only fit in one direction due to the notch. Memory size can
vary between sockets.

Installation Guide

DDR

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 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, 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.
