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 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.

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.
CPU side
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.

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
74
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
75

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:
76
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.

When you select an option, information explaining the selection is displayed in the area below the Memory Timing box.
Row Address Strobe
Clicking on View SPD… displays a memory information window. This is for information only and is not editable.
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

issuing an active command and the read/write commands. Adjustable from 1 to 15.
79
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
80
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 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.
