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

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.
Hardware Installation
Preparing the Motherboard
The motherboard shipped in the box does
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

Installing and Configuring the NVIDIA nForce 650i Ultra Motherboard
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 Memory DIMMs
Your new motherboard has four 1.8V 240-pin slots for DDR2
memory. These slots support 256 Mb, 512 Mb and 1 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
10 for the location of the memory slots on the card)
14
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.

Card-edge side
DIMM Slot 0
DIMM Slot 2
DIMM Slot 1
DIMM Slot 3
Hardware Installation
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.
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
15
Installing and Configuring the NVIDIA nForce 650i Ultra Motherboard
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.

Power Connections
This motherboard requires an ATX power supply. Make sure you
have enough power to cover all the expansion cards you will be
installing. To determine what you power requirements are for your
specific configuration, refer to
24-pin ATX Power (PWR1)
PWR1 is the main power supply connector located along the edge of
the board next to the DIMM slots. Make sure that the power supply
cable and pins are properly aligned with the connector on the
motherboard. Firmly plug the power supply cable into the connector
and make sure it is secure.
