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

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 Align notches with

notches on the CPU

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)

 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

CPU side

Card-edge side

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

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.

Connecting Internal Headers

Front Panel Header

The front panel header on this motherboard is one

connector used to connect the following four cables:

 PWRLED

Attach the front panel power LED cable to

these two pins of the connector.

The Power LED indicates the system’s

status. When the system is in S0 status,

the LED is

on. When the system is in S1, S3, S4, S5

status, the LED is off.

Note: The power LED cable in some chassis is a three pin connector with

the pins installed in positions 1 and 3. If your chassis has a three

pin connector, you will need to remove pin 3 and put it into

position 2 or you can use a pair of scissors to cut out position 2.

Most chassis come with a two pin connector.

 PWRSW

Attach the power button cable from the case to these two pins.

Pressing the power button on the front panel turns the system on

off rather than using the power supply button.

 HD_LED

Attach the hard disk drive indicator LED cable to these two pins.

The HDD indicator LED indicates the activity status of the hard

disks.

 RESET

Attach the Reset switch cable from the front panel of the case to

these two pins. The system restarts when the RESET switch is

pressed.

Hardware Installation

Expansion Slots

The NVIDIA 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.nvidia.com/estore.

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.

1 – PCI slots

2 – x1 PCIe slots

4 – Primary PCIe x16

slot (GPU1)

Installing and Configuring the NVIDIA 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.

Hardware Installation

2. Return the jumper setting to normal (pins 2 and

3. Together with the jumper cap).

4. Turn the AC power supply back on.

Manual Tuning

The Manual Tuning option provides the ability to adjust

motherboard settings, adjust CPU settings, and make changes to the

BIOS.

Adjust Motherboard Settings

The controls in the Adjust Motherboard Settings screen let you adjust

the performance of the system clocks, system voltages, memory

controller timings, and system fans. By manually adjusting these

speeds you are able to either increase performance for gaming, or

reduce performance to conserve power and create a quieter

environment.

Figure 19 shows the Adjust Motherboard Settings screen. Note that

as you pass the cursor over the various adjustments, notes display at

the bottom of the screen to explain each setting.

The number to the right of the slider is the new bus speed that will

be applied. Make adjustments by using the mouse to drag the slider.

All changes take effect immediately after selecting Apply; however,

these setting only remain active for the current Windows session.

This allows you to safely return to Windows if a crash occurs, with

no possibility of boot issues since the changes are not made directly

to the BIOS settings.

Using NVIDIA Software

Note: All changes on Adjust Motherboard Settings are dynamically made when you

apply them, and only remain active for the current Windows session. You can

save these settings as a profile for use later by using the Profile menu item. If

a setting does not allow a change, it probably requires a reboot and should

be changed in the BIOS or from the Dynamic BIOS Access page (if available).

CAUTION: Increasing the voltage or the clock speed of a component may

void its warranty due to exceeding recommended specifications. NVIDIA

and the board manufacturer are not responsible for damage that may occur

when component tolerances are exceeded.

System Clocks

This section of the Adjust

Motherboard Settings allows

you to adjust the reference

Installing and Configuring the NVIDIA nForce 650i Ultra Motherboard

clocks for the FSB, the SPP PCI Express, and the MCP PCI Express.

Note that as you change the slider for the FSB reference clock, the

CPU core frequency, the FSB Frequency and the memory bus

frequency are dynamically changed.

System Voltages

CAUTION: Overvoltaging any component can result in damage.

In this section of the Adjust Motherboard Settings you must

understand what you are changing. Overvoltaging any of the

components can result in damage

to the components. From this

menu, you can adjust the following

voltages:

 CPU

 Memory

 FSB

 HyperTransport SSP MCP

 nForce SPP

 nForce MCP

 Auxiliary

Always note the color of the

indicator square to the right of each

slider. Green indicates the voltage is

within range and will not damage any

components. Yellow means to proceed

with caution; you are no longer in the

safe range. If the indicator square is red,

you are possible overvoltaging the

component and could be causing damage.

Using NVIDIA Software

System Fans

This section of the Adjust Motherboard Settings menu allows you to

control the CPU, System, nForce, MCP, and the auxiliary fans. You

can either set all the fans to automatic control or you can manually

control each fan.

When in manual control, you can specify to show the temperatures

in Celsius or Fahrenheit.

Memory Timing

This section of the Adjust Motherboard Settings allows you to adjust

various memory timings and cycles.

 Row Address Strobe

Adjusts the minimum RAS active time. This is the amount of time

between a row being activated by Precharge and deactivated. A

row cannot be deactivated until tRAS has completed. The lower

this value, the faster the performance. However, if it is set too low

it can cause data corruption by deactivating the row to soon.

Adjustable from 1 to 63.

 Write Recovery Time

Memory timing that determines the delay between a write

command and a Precharge command is set to the same bank of

memory. Adjustable from 1 to 15.

 W to R Termination Turnaround

The Write-to-Read time is the number of clock cycles between the

last write data pair and the subsequent READ command to the

same physical block. Adjustable from 1 to 15.

 RAS to CAS access

The RAS-to-CAS access (tRCD) is the amount of time in cycles for

Adjustable from 1 to 15.

Installing and Configuring the NVIDIA nForce 650i Ultra Motherboard

 RAS to RAS Delay

The RAS-to-RAS delay (tRRD) is the is the amount of cycles it

takes to activate the next bank of memory (this is the opposite of

tRAS). The lower the timing the better the system performance.

However, this scenario can cause instability. Adjustable from 1 to

15.

 Refresh Rate

This value is filled in by the system and can not be changed by

the user.

 Memory bank switch

The row Precharge time (tRP) is the minimum time between active

commands and the read/writes of the next bank on the memory

module. Adjustable from 1 to 15.

 R to W Turnaround

The Read-to-Write turnaround (tRWT) is a the amount of cycles

for the command to be executed when a Write command is

received. Adjustable from 1 to 15.

 R to R Timing

the Read-to-Read time (tRDRD) is the number of clock cycles

between the last read and the subsequent READ command to the

same physical bank. Adjustable from 1 to 15.

 Row Cycle Time

The Row Cycle Time is the minimum time in cycles it take a row

to complete a full cycle. This can be determined by

tRC=tRAS+tRP. If this value is set too short, it can cause

corruption of data. If this value is set too high, it causes a loss in

performance but an increase in stability. Adjustable from 1 to 63

cycles

 W to R Command Delay

The Write-to-Read (tWRD) command delay is the amount of cycles

required between a valid write command and the next read

command. A lower cycle time results in better performance but is

can instability. Adjustable from 0 to 6 cycles.

 W to W Timing

The Write-to-Write (tWRWR) timing is the number of clock cycles

Using NVIDIA Software

between the last write and the subsequent Write command to the

same physical bank. Adjustable from 2 to 15 cycles.

 CAS Latency

The CAS Latency (tCL) is the time (in number of clock cycles)

that elapses after the memory controller sends a request to read a

memory location and before the data is sent to the module's

output pins. The value shown cannot be changed.

 Clock Drive Strength

This value is filled in by the system and can not be changed by

the user.

 Command Per Clock

The Command Per Clock (tCPC) sets the Command Rate for the

memory controller. The value shown cannot be changed

 Async Latency

This value is filled in by the system and can not be changed by

the user.

Adjust GPU Settings

Use this interface to adjust the graphics processing unit (GPU) on

your video card(s). You can override the shipped clock frequencies of

your GPU and GPU memory and set the GPU fan speed. Increasing

the clock speeds increases your GPU performance and may require

adjusting cooling to maintain the same level of reliability.

Automatic Tuning

The NVIDIA nTune performance manager uses a complex searching

algorithm to determine the best possible and most stable performance

for you system. The nTune tuning engine pushes your system to the

limits to test the highest possible performance settings. Because of

this, there may be instances of system hangs during the testing.

When you restart the system, nTune continues its tuning process

until the process is complete. It is highly recommended that you

check the Select to continue the tuning process upon reboot box at the

bottom of the Tune System screen. The effects of the tuning process

apply to the current Windows session only.

The nTune tuning engine runs internal benchmark tests on your

system and creates performance profiles and rules.

CAUTION: Make sure to save and close all work prior to running the Tune

System function. Close all applications and do not perform other tasks

during the tuning session.

Three tuning options are available on the Tune System menu:

 Course tuning takes approximately 20 minutes to run while it

adjusts system bus speeds and parameters. It first saves current bus

speeds as two profiles: the Default.npe file with current bus speeds

and Bestsystem.npe with the highest passing settings.

 Fine tuning takes approximately three (3) hours and performs a

more complex tuning on bus speeds, memory timings, and voltages.

This more complex testing achieves maximum performance.

 Tuning using custom settings allows you to select specific areas to

test and the duration of the tests. Remember that a longer tuning

session results in more precise and stable settings. The progress of

Using NVIDIA Software

your test and the results upon completion are displayed when the

benchmarks are being executed. You can cancel the tests at any

time.

NVIDIA Networking

The NVIDIA Networking function configures and controls NVIDIA

networking hardware integrated into the NVIDIA MCP. In addition

to the typical network configuration functions that are controlled

using the Windows Network Connections panel, the NVIDIA

networking solution includes several key features that are accessed

using the NVIDIA control panel.

 FirstPacket

FirstPacket provides a better gaming experience over a broadband

connection when multiple applications on the same PC are

simultaneously transmitting data to the Internet

 TCP/IP Acceleration

When TCP/IP acceleration is enabled, it lowers the CPU

utilization and provides overall better system performance when the

networking traffic is mainly TCP/IP.

To launch the NVIDIA Control Panel, select Start¾All Programs

¾NVIDIA Corporation¾NVIDIA Control Panel. Click on the Networking

icon.

Using NVIDIA Software

105

Performance

The Performance option on the Networking Control Panel

Categories screen provides the means to configure FirstPacket settings

and to set TCP/IP acceleration configuration.

Figure 28. Networking Control Panel Categories

First Packet

NVIDIA FirstPacket offers a new way to manage the traffic on your

personal computer, allowing you to more effectively manage and

improve the performance of networked games and other applications

that are sensitive to network delay (latency), such as Voice-over-IP

(VoIP).

FirstPacket creates an additional transmit queue in the network

driver so that network applications can share a limited resource.

Based on user preference, FirstPacket can expedite transmission for

user-approved network applications.

For example, when FirstPacket is enabled:

 A game that was previously unplayable can be completely usable

 VoIP connections will not be dropped due to the network traffic

on a local computer.

Installing and Configuring the NVIDIA nForce 650i Ultra Motherboard

106

Use the following procedure to enable or disable the ability to have

network traffic to prioritized for optimal performance:

1. Select Configure FirstPacket Settings under Performance on the

Networking Control Panel Categories screen to display the

Configure FirstPacket Settings screen.

2. Click the Settings tab.

3. Click Enable FirstPacket (recommended) to enable the options that

define the speed of the broadband connection. This information is

needed by the FirstPacket software to appropriately prioritize

network traffic.

Select the appropriate speed for

your network. For example, if

your broadband connection is a

cable connection, click the Cable

button.

Custom bandwidth connections

can be directly configured in the

provided text box.

Using NVIDIA Software

107

4. Define the applications to accelerate by clicking Program Prioritized

by FirstPacket.

5. Click Add to browse for an executable gamming applications. For

example, if you want to accelerate a game such as Serious Sam 2,

look for the Sam2.exe and add it.

6. Click Apply.

Note: Only applications that are added to the Programs Prioritized by

FirstPacket section are prioritized and benefit from FirstPacket

technology

TCP/IP Acceleration

Note: Enabling TCP/IP acceleration enhances your network performance but can

cause your network traffic to bypass the firewall because all processes are

off-loaded to the hardware.

NVIDIA TCP/IP Acceleration technology is a networking solution

that moves the processing of TCP/IP network traffic from your

computer’s CPU to its nForce hardware resulting in greatly

improved system performance.

NVIDIA TCP/IP Acceleration provides deep levels of networking

Installing and Configuring the NVIDIA nForce 650i Ultra Motherboard

108

and traffic inspections at full-duplex gigabit Ethernet speeds. Overall

system performance is greatly improved because the CPU is not tied

up processing network traffic, especially at gigabit Ethernet speed.

Using NVIDIA Software

109

In traditional networking environments, inspecting packets is

laborious and affects CPU overhead, memory bandwidth, and overall

system latency. In comparison, the NVIDIA TCP/IP Acceleration

engine discards bad packets before the CPU detects them. In addition,

good packets take an “express lane” and bypass the traditional

“network stack” process, improving overall throughput and lowering

CPU utilization.

T configure TCP/IP acceleration, select Set TCP/IP Acceleration

configuration from the Networking screen. Note that by default,

TCP/IP acceleration is turned off (the Not be hardware-accelerated

radio button is checked). Click the Use hardware-acceleration

(recommended) radio button to enable TCP/IP acceleration. Click

Apply to save changes.
