Safety Instructions

EVGA

8

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.

Hardware Installation

Preparing the Motherboard

Installing the CPU

Be very careful when handling the CPU. Make sure not to bend or break any
pins in 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.

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.

9

Align notches with
notches on the CPU

EVGA

Note: 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 instruction that came with you fan assembly. Be sure that the fan
orientation is correct for your chassis type and your fan assembly.

Installing System Memory (DIMMs)

Your new motherboard has four 240-pin slots for DDR2-800 memory. These
slots support 256 MB, 512 MB,1 GB, and 2Gb DDR2. 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 6 for the
location of the memory slots.)

EVGA

10

 One DIMM:

Install into slot 1. You can install the DIMM into any slot, however, slot 1 is
preferred.

 Two DIMMs:

Install into either slots 1 and 3 or 2 and 4. The four DIMM sockets are
divided into two colors to help you identify the channel pairs. To obtain best
performance, simply mount DIMM sockets of the same color.

 Four DIMMs:

Install into slots 1, 2, 3, and 4.

Hardware Installation

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.

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.

Installing the Motherboard

DIMM Slot 1
DIMM Slot 2

DIMM Slot 3
DIMM Slot 4

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. Determine if it would be easier to make all the
connections prior to this step or to secure the motherboard and then make all
the connections. It is normally easier to secure the motherboard first.

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

Note: 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.

11

EVGA

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 a System Case

Most computer cases 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 nine (9) spacers.

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

chassis.

Connecting Cables and Setting
Switches

EVGA

12

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.

This section takes you through all the connections and switch settings necessary
on the motherboard. This will include:

Connecting IDE Hard Disk Drives

The IDE connector supports Ultra ATA 133/100/66 IDE hard disk drives.

1. Connect the blue connector (the cable end with a single connector) to the

motherboard.

2. Connect the black connector (the cable with the two closely spaced black

and gray connectors) to the Ultra ATA master device.

3. Connect the gray connector to a slave device.

If you install two hard disk drives, you must configure the second drive as a
slave device by setting its jumper accordingly. Refer to the hard disk
documentation for the jumper settings.

Note: If an ATA-66/100 disk drive and a disk drive using any other IDE transfer

protocol are attached to the same cable, the maximum transfer rate between
the drives may be reduced to that of the slowest drive.

PCI Slots

The three PCI slots support many expansion cards such as a LAN card, USB
card, SCSI card and other cards that comply with PCI specifications. When
installing a card into the PCI slot, be sure that it is fully seated. Secure the card’s
metal bracket to the chassis back panel with the screw used to hold the blank
cover.

PCI Express x1 Slots

There are two PCI Express x1 slots that are designed to accommodate less
bandwidth-intensive cards, such as a modem or LAN card. The x1 slots provide
250 MB/sec bandwidth.

PCI Express x16 Slot

The PCI Express x16 slot is reserved for graphic or video cards. The bandwidth
of the x16 slot is up to 4GB/sec (8GB/sec concurrent).

When installing a PCI Express x16 card, be sure the retention clip snaps and
locks the card into place. If the card is not seated properly, it could cause a
short across the pins. Secure the card’s metal bracket to the chassis back panel
with the screw used to hold the blank cover.

Clear CMOS Button

The motherboard uses the CMOS RAM to store all the set parameters within
the system BIOS. The CMOS can be cleared by press the RESET CMOS
button.

Configuring the BIOS

Enter BIOS Setup

The BIOS is the communication bridge between hardware and software.
Correctly setting the BIOS parameters is critical to maintain optimal system
performance.

Use the following procedure to verify/change BIOS settings.

1. Power on the computer.

2. Press the Del key when the following message briefly displays at the bottom

of the screen during the Power On Self Test (POST).

Press F1 to continue, DEL to enter Setup.

Pressing Del takes you to the Phoenix-Award BIOS CMOS Setup Utility.

It is strongly recommended that you do not change the default BIOS settings.

Changing some settings could damage your computer.

Main Menu

The main menu allows you to select from the list of setup functions and two
exit choices. Use the
options or press
keys to position the selector in the option you choose. To go back to the
previous menu, press

Note that on the BIOS screens all data in white is for information only, data in yellow

Installing Drivers and

Software

It is important to remember that before installing the driver CD that is shipped in the

kit, you need to load your operating system. The motherboard supports
Windows XP 32bit and 64bit and is Vista-capable.

The kit comes with a CD that contains utility drivers and additional NVIDIA
software.

The CD that has been shipped with your EVGA motherboard contains the
following software and drivers:

 NVIDIA nForce motherboard drivers
 Audio drivers
 RAID Drivers
 JMicron Drivers
 Adobe Acrobat Reader
 User’s Manual

Drivers Installation

1. Insert the EVGA nForce 730i installation CD for the motherboard

included in the kit.

2. The CD will autorun, install the drivers and utilities listed on the install

screen.

If it does not run, go to My Computer and click on the CD to open.
