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.
11
Preparing the Motherboard
The motherboard shipped in the box does not contain a CPU or memory. You
need to purchase a CPU, a CPU fan assembly, and memory to complete this
installation.
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 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
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.

Hardware Installation
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 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 technologies for x8 and
x16 devices. 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 9 for the location of the memory slots on the
card)
One DIMM: Install into slot 0. You can install the DIMM into any slot,
however, slot 0 is preferred.
‰ Two DIMMs: Install into either slots 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 into the slots on the
motherboard. 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.
13
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. 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 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.
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.

Expansion Slots
Hardware Installation
PCI Slots
The two 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 are two PCI Express x1 slots that are 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
bandwidth of the x16 slot is up to 4GB/sec (8GB/sec concurrent). The design
of this motherboard supports dual PCI-Express graphics cards using NVIDIA’s
SLI technology with multiple displays.
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.
To configure for SLI, follow the instructions that come with the SLI kit (the kit
is purchased separately from the motherboard).
25
Jumper Settings
The motherboard contains a 3-pin BIOS configuration jumper that enables all
board configurations to be done in the BIOS Setup program.
The silk screen on the motherboard shows a ∆ next to pin 1.
Clear CMOS Jumper: CLR_CMOS
The motherboard uses the CMOS RAM to store all the set parameters. The
CMOS can be cleared by removing the CMOS jumper.
Use the following procedure to clear CMOS:
1. Turn off the AC power supply and connect pins 1 and 2 together using the
jumper cap.
2. Return the jumper setting to normal (pins 2 and
3. Together with the jumper cap).
4. Turn the AC power supply back on.

Installing Graphics Cards in an
SLI Configuration
NVIDIA SLI (Scalable Link Interface) is a revolutionary technology that allows
two NVIDIA SLI graphics cards to work together to deliver incredible 3D
graphics performance.
Your new motherboard can support up to two PCI Express graphics cards
linked using SLI.
Building an SLI System
Determine Component and Operating System Needs
To build an NVIDIA SLI system, you are going to need the following
components:
AN NVIDIA SLI-ready nForce motherboard
‰ Two NVIDIA SLI-Ready certified PCI Express graphics cards (with
matching GPUs)
‰ An NVIDIA SLI-Ready power supply
‰
For a complete list of certified components and a matrix to determine the
power supply required for your particular graphic cards, go to:
http://www.slizone.com/content/slizone/build.html.
65
While NVIDIA recommends an SLI-Ready power supply, the following table
provides some general power supply recommendations based on testing
performed in the NVIDIA SLI validation lab.
Table 6.
Recommended Power Supplies
NVIDIA SLI
System Type
Minimum Recommended PCI Express
Power Supply
Extreme SLI PC
NVIDIA has tested the majority of power supplies in this high
power category and therefore only recommends an SLI-ready
power supply.
Ultra High-end SLI PC
You must have a power supply that can provide a minimum
of +12V @ 22A of dedicated power for the two graphics
cards. Of this 22A requirement, +12V @ 5.5A must be
available to each of the two PCI Express 6-pin auxiliary
power supply connectors. The remaining 11A must be
supplied to the motherboard for dedicated graphics card use.
High-end SLI PC
Minimum of 500-600W Power Supply with a minimum of
+12V @ 30A for all PC components.
Mid-range SLI PC
Minimum of 450-500W Power Supply with a minimum of
