Preparing the motherboard
¾ Installing the CPU
¾ Installing the CPU fan
¾ Installing the memory

Installing the motherboard

Connecting cables and setting switches

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.
CPU side
DIMM Slot 0
DIMM Slot 2
DIMM Slot 1
DIMM Slot 3
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.

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 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.

for accessing, monitoring, and adjusting your system components
(including bus speeds and voltages) with clear, user-friendly control
panels.
Overclock your system for the highest performance, or underclock it
for a nearly silent operation. All changes are performed within the
Microsoft Windows interface, enabling full functionality without the
need to make changes in the BIOS and reboot your system.
Use the following procedure to access nTune:
1. From the desktop, select Start¾All Programs¾NVIDIA

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.
74

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
75

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.
76

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

Using NVIDIA Software

issuing an active command and the read/write commands.
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.

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.

104

Using NVIDIA Software

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.

105

Installing and Configuring the NVIDIA nForce 650i Ultra Motherboard

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.

106

Using NVIDIA Software

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
107

Installing and Configuring the NVIDIA nForce 650i Ultra Motherboard

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.

108

Using NVIDIA Software

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.
