Installation Guide

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 slo ts 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.

Installation Guide

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.

7ZXC Motherboard

Memory Installation

The motherboard has 3 dual inline memory mod ule (DIM M) sock ets supp ort 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.

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.

Install memory in any combination table:

DIMM 168-pin SDRAM DIMM Modules
DIMM 1 Supports 16 / 32 / 64 / 128 / 256 / 512 MB X 1 pcs
DIMM 2 Supports 16 / 32 / 64 / 128 / 256 / 512 MB X 1 pcs
DIMM 3 Supports 16 / 32 / 64 /128 / 256 / 512 MB X 1 pcs

★Total System Memory (Max 1.5GB)

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