Installing the CPU fan

Installing the memory

Installing the motherboard

Connecting cables and setting switches

Safety Instructions

To reduce the risk of re, electric shock, and injury, always follows basic safety precautions.

Remember to remove power from your computer by disconnecting the AC main source before re-

moving or installing any equipment from/to the computer chassis.

Preparing the Motherboard

The motherboard shipped in the box does not contain a CPU or memory. You need to purchase

these components to complete this installation.

nForce 750i SLI Motherboard

Installing the CPU

Be very careful when handling the CPU. Make sure not to bend or break any pins on the back. 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 moth-

erboard.

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.

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 as-

sembly. Be sure that the fan orientation is correct for your chas-

sis type and your fan assembly.

Align notches with
notches on the CPU

EVGA

One DIMM: Install into slot 0. You can install the DIMM into any slot, however, slot 0 is pre-

ferred.

Two DIMMs: Install into either slots 0 and 1 or 2 and 3. The idea is to not have the DIMMs in ad-

jacent 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.

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 into the DIMM

slot. The plastic clips at both sides of the DIMM slot automatically lock the DIMM into the

connector.

Installing 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 recommendations for installing memory. (See Figure 1 on page 4

for the location of the memory slots.)

nForce 750i SLI Motherboard

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. 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 rst.

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.

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 airow 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 ts securely. If the I/O shield does not t 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 nine (9) 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 in

-

struction.

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

Expansion Slots

The EVGA nForce 750i SLI motherboard contains six expansion slots, three PCI Express slots and

three PCI slots. For a full list of PCI Express x16 graphics card supported by this motherboard, go to

www.nvidia.com/estore.

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 Slot

There is one PCI Express x1 slot that is designed to

accommodate less bandwidth-intensive cards, such

as a modem or LAN card. The x1 slot provides 250

MB/sec bandwidth.

PCI Express x16 Slots

These two PCI Express x16 slots are reserved for graphics or video cards. The design of this mother-

board supports two PCI-Express graphics cards with x8 bandwith using NVIDIA’s SLI technology.

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.
