Safety Instructions

Hardware Installation

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.

Installing and Configuring the XFX nForce 650i Ultra Motherboard

notches on the CPU

Preparing the Motherboard

The motherboard shipped in the box does 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.

CPU side

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 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.

DIMM Slot 0

DIMM Slot 2

DIMM Slot 1

DIMM Slot 3

Card-edge side

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 and Configuring the XFX nForce 650i Ultra 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. 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.

USB Headers

This motherboard contains four (4) USB 2.0 ports that are exposed on the rear panel of the chassis. The motherboard also contains two 10-pin internal header connectors onboard that can be used to connect an optional external bracket containing four (4) more USB 2.0 ports.

1. Secure the bracket to either the front or rear panel of your

chassis (not all chassis are equipped with the front panel option).

2. Connect the two ends of the cables to the USB 2.0 headers

on the motherboard.

Expansion Slots

The XFX nForce 650i Ultra motherboard contains six expansion slots, one PCI Express slot and three PCI slots. For a full list of PCI Express x16 graphics card supported by this motherboard, go to www.xfxforce.com.

1 – PCI slots 2 – x1 PCIe slots 4 – Primary PCIe x16

slot (GPU1)

Figure 4. Expansion Slots

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.

Installing and Configuring the XFX nForce 650i Ultra Motherboard

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

There is one PCI Express x16 slot that is reserved for a graphics or video card. 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.

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.

Software Installation

Note: 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 XFX motherboard contains the following software and drivers:

Windows XP Drivers Install

Note: When installing the graphics drivers, the resolution defaults to the lowest

setting (typically 800 x 600), making your display very large. Adjust accordingly.

1. Insert the XFX nForce 650i Ultra installation CD for the graphics drivers

included in the kit.

Note: If you have multiple graphics cards installed, you will be asked multiple times

for all events once the drivers are installed.

2. Run
