 Preparing the motherboard

¾ Installing the CPU ¾ Installing the CPU fan ¾ Installing the memory

 Installing the motherboard  Connecting cables and setting switches

Safety Instructions

To reduce the risk of fire, electric shock, and injury always follow basic safety precautions.

Remember to remove power from your computer by disconnecting the AC main source before removing or installing any equipment from/to the computer chassis.

EVGA 7

Preparing the Motherboard

Installing the CPU

Be very careful when handling the CPU. Make sure not to bend or break any pins within the socket. Hold the processor only by the edges and do not touch the bottom of the processor.

Use the following procedure to install the CPU onto the motherboard.

1. Unhook the socket lever by pushing down and away from

the socket.

2. Lift the load plate. There is a protective socket cover on

the load plate to protect the socket when there is no CPU installed.

EVGA 8

3. Remove the protective socket cover from the load plate.

4. Remove the processor from its protective cover, making

sure you hold it only by the edges. It is a good idea to save the cover so that whenever you remove the CPU, you have a safe place to store it.

5. Align the notches in the processor with the notches on the socket.

6. Lower the processor straight down into the socket

with out tilting or sliding it into the socket

Make sure the CPU is fully seated and level in the socket.

7. Close the load plate over the CPU and press down while

you close and engage the socket lever.

Installing the CPU Fan

There are many different fan types that can be used with this motherboard. Follow the instructions that came with your fan assembly. Be sure that the fan orientation is correct for your chassis type and your fan assembly.

Align notches with

notches on the CPU

Installing System Memory (DIMMs)

Your new motherboard has four 1.8V 240-pin slots for DDR2 memory. These slots support 256 MB, 512 MB, 1 GB, and 2 GB DDR2 memory modules. They also support dual channel DDR2 memory technology up to 10.7GB/s. There must be at least one memory bank populated to ensure normal operation. Use the following the recommendations for installing memory. (See Figure 1 on page i for the location of the memory slots.)

 One DIMM: Install into slot 0. You can install the DIMM into any slot however, slot 0

is preferred.

 Two DIMMs: Install into either slot 0 and 1 or 2 and 3. The idea is to not have the

DIMMs in adjacent slots.

 Four DIMMS: Install into slots 0, 1, 2, and 3.

Use the following procedure to install memory DIMMs. Note that there is only one gap near the center of the DIMM slot. This slot matches the slot on the memory DIMM to ensure the component is installed properly.

CPU side

DIMM Slot 0 DIMM Slot 1

DIMM Slot 2

DIMM Slot 3

1. Unlock a DIMM slot by pressing the module clips outward.

2. Align the memory module to the DIMM slot and insert the module vertically while

applying light downward pressure to properly seat the DIMM. The plastic clips at both sides of the DIMM slot automatically lock the DIMM into the connector.

EVGA 9

Installing the Motherboard

The sequence of installing the motherboard into the chassis depends on the chassis you are using and if you are replacing an existing motherboard or working with an empty chassis. It is recommended to secure the motherboard first before making all connections.

Use the following procedure to install the I/O shield and secure the motherboard into the chassis.

Be sure that the CPU fan assembly has enough clearance for the chassis covers to

lock into place and for the expansion cards. Also make sure the CPU Fan assembly is aligned with the vents on the covers.

Installing the I/O Shield

The motherboard kit comes with an I/O shield that is used to block radio frequency transmissions, protects internal components from dust and foreign objects, and promotes correct airflow within the chassis.

Before installing the motherboard, install the I/O shield from the inside of the chassis. Press the I/O shield into place and make sure it fits securely. If the I/O shield does not fit into the chassis, you would need to obtain the proper size from the chassis supplier.

Securing the Motherboard into the Chassis

Most computer chassis have a base with mounting studs or spacers to allow the mother board to be secured to the chassis and help to prevent short circuits. If there are studs that do not align with a mounting hole on the motherboard, it is recommended that you remove that stud to prevent the possibility of a short circuit. In most cases, it is recommended to secure the motherboard using a minimum of eight (8) to ten (10) spacers.

1. Carefully place the motherboard onto the studs/spacers located inside the chassis.

2. Align the mounting holes with the studs/spacers.

3. Align the connectors to the I/O shield.

4. Ensure that the fan assembly is aligned with the chassis vents according to the fan

assembly instruction.

5. Secure the motherboard with a minimum of eight-to-ten screws.
