Introduction  
NVIDIA nTune 5.0  
The Performance category is used to configure and manage NVIDIA nTune.  
The NVIDIA nTune program is a full-featured application 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:  
3. From the desktop, select Start¾All Programs¾NVIDIA Corporation¾NVIDIA  
Control Panel.  
4. Select Performance to display Performance Control Panel Categories.

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.  
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 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.  
xvii  
Installing and Configuring the EVGA nForce 680i SLI Motherboard  
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 SSPMCP  
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.  
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.

Introduction  
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 issuing  
an active command and the read/write commands. Adjustable from 1 to 15.  
xix  
Installing and Configuring the EVGA nForce 680i SLI 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 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.  
xx  
Introduction  
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.

Introduction  
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.npefile with current bus speeds and  
Bestsystem.npewith 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 your test and the results  
upon completion are displayed when the benchmarks are being executed.  
You can cancel the tests at any time.

Introduction  
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.  
Teaming  
Teaming increase bandwidth when serving files in a LAN environment.  
Enables multiple integrated network interfaces to work together seamlessly.  
To launch the NVIDIA Control Panel, select Start¾All Programs ¾NVIDIA  
Corporation¾NVIDIA Control Panel. Click on the Networking icon.  
xli  
Installing and Configuring the EVGA nForce 680i SLI Motherboard  
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.  
xlii  
Introduction  
Use the following procedure to enable or disable the ability to have network  
traffic to prioritized for optimal performance:  
25.Select Configure FirstPacket Settings under Performance on the  
Networking Control Panel Categories screen to display the Configure  
FirstPacket Settings screen.  
26.Click the Settings tab.  
27. 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.  
xliii  
Installing and Configuring the EVGA nForce 680i SLI Motherboard  
28. Define the applications to accelerate by clicking Program Prioritized by  
FirstPacket.  
29. 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.exeand add it.  
30. 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 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.  
xliv  
Introduction  
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.  
xlv  
Installing and Configuring the EVGA nForce 680i SLI Motherboard  
Teaming  
NVIDIA Teaming technology improves network throughput by distributing  
traffic efficiently across all available Ethernet interfaces. In normal network  
conditions, both transmit and receive traffic are distributed.  
NVIDIA Teaming technology also improves network uploading time. If one of  
the physical Ethernet interfaces fails, the network can remain accessible because  
the remaining interface can take over the network traffic of the failed interface,  
achieving “fault tolerance”. The operating system and network application do  
not detect a network failure because network connection is bound to the logical  
interface rather than to a single physical interface.  
By utilizing the multiple interfaces on an NVIDIA nForce system and load  
balancing traffic among them, network users can gain fault tolerance and  
achieve greater throughput.  
The Adjust Teaming Configuration screen has tow radio buttons:  
Combine my network adapters (recommended).  
NVIDIA Teaming technology combines two or more NVIDIA Ethernet  
interfaces to increase your network bandwidth and also provides load  
balancing and fault tolerance benefits.  
Do not combine my network adapters (no teaming).  
This is also the default setting. You may want to disable network adapter  
teaming if your system is not operating as a file server. When disabled, each  
NVIDIA Ethernet interface works independently.  
xlvi  
Introduction  
Use the following procedure to configure Teaming:  
31. Select Start¾All Programs¾NVIDIA Corporation¾NVIDIA Control Panel  
to display the NVIDIA Control Panel.  
32. Click on the networking icon to display the Networking Control Panel  
Categories.  
33. Select Adjust Teaming configuration to display the teaming configuration  
window. Note that by default, Teaming is disabled.  
34. Select Combine my network adapters (recommended) radio button to  
enable Teaming.  
35. Click Apply to enable teaming.

13  
Installing and Configuring the EVGA nForce 680i SLI Motherboard  
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. 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.  
36.Unhook the socket lever by pushing down and away  
from the socket.  
37.Lift the load plate. There is a protective socket  
cover on the load plate to protect the socket when  
there is no CPU installed.  
38. Remove the protective socket cover from the load  
plate.  
39. 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.  
40. Align the notches in the processor with the  
notches on the socket.  
41. Lower the processor straight down into the socket  
with out tilting or sliding it into the socket  
Align notches with  
notches on the CPU  
Note: Make sure the CPU is fully seated and level in the  
socket.  
42. Close the load plate over the CPU and press down  
while you close and engage the socket lever.

Hardware Installation  
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.  
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  
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.  
43.Unlock a DIMM slot by pressing the module clips outward.  
44. 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.  
15  
Installing and Configuring the EVGA nForce 680i SLI 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  
motherboard 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.

Power Connections  
This motherboard requires an ATX power supply. To support a PCI Express  
motherboard with the addition of dual graphics cards using NVIDIA SLI  
technology, you are going to need a minimum of a 500W 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 www.SLIzone.com.  
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.

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.

PCI Express x1 Slot  
There is 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  
These two PCI Express x16 slots are reserved for graphics or video cards. The  
bandwidth of the x16 slot is up to 4GB/sec (8GB/sec concurrent). The design  
of this motherboard supports dual PCI-Express graphics cards using NVIDIA’s  
SLI technology with multiple displays.  
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 1  
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.  
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).

the selection is displayed in the area below the  
Memory Timing box.  
Clicking on View SPD… displays a  
memory information window. This is  
for information only and is not editable.  
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 issuing  
an active command and the read/write commands. Adjustable from 1 to 15.  
75  
Installing and Configuring the EVGA nForce 680i SLI 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 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.

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.npefile with current bus speeds and  
Bestsystem.npewith 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 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.  
Teaming  
Teaming increase bandwidth when serving files in a LAN environment.  
Enables multiple integrated network interfaces to work together seamlessly.  
To launch the NVIDIA Control Panel, select Start¾All Programs ¾NVIDIA  
Corporation¾NVIDIA Control Panel. Click on the Networking icon.  
97  
Installing and Configuring the EVGA nForce 680i SLI Motherboard  
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.  
98  
Installing and Configuring the EVGA nForce 680i SLI Motherboard  
Use the following procedure to enable or disable the ability to have network  
traffic to prioritized for optimal performance:  
27.Select Configure FirstPacket Settings under Performance on the  
Networking Control Panel Categories screen to display the Configure  
FirstPacket Settings screen.  
28.Click the Settings tab.  
29. 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.  
99  
Installing and Configuring the EVGA nForce 680i SLI Motherboard  
30. Define the applications to accelerate by clicking Program Prioritized by  
FirstPacket.  
31. 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.exeand add it.  
32. 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 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.  
100  
Installing and Configuring the EVGA nForce 680i SLI Motherboard  
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.  
101  
Installing and Configuring the EVGA nForce 680i SLI Motherboard  
Teaming  
NVIDIA Teaming technology improves network throughput by distributing  
traffic efficiently across all available Ethernet interfaces. In normal network  
conditions, both transmit and receive traffic are distributed.  
NVIDIA Teaming technology also improves network uploading time. If one of  
the physical Ethernet interfaces fails, the network can remain accessible because  
the remaining interface can take over the network traffic of the failed interface,  
achieving “fault tolerance”. The operating system and network application do  
not detect a network failure because network connection is bound to the logical  
interface rather than to a single physical interface.  
By utilizing the multiple interfaces on an NVIDIA nForce system and load  
balancing traffic among them, network users can gain fault tolerance and  
achieve greater throughput.  
The Adjust Teaming Configuration screen has tow radio buttons:  
Combine my network adapters (recommended).  
NVIDIA Teaming technology combines two or more NVIDIA Ethernet  
interfaces to increase your network bandwidth and also provides load  
balancing and fault tolerance benefits.  
Do not combine my network adapters (no teaming).  
This is also the default setting. You may want to disable network adapter  
teaming if your system is not operating as a file server. When disabled, each  
NVIDIA Ethernet interface works independently.  
102  
Installing and Configuring the EVGA nForce 680i SLI Motherboard  
Use the following procedure to configure Teaming:  
33. Select Start¾All Programs¾NVIDIA Corporation¾NVIDIA Control Panel  
to display the NVIDIA Control Panel.  
34. Click on the networking icon to display the Networking Control  
Panel Categories.  
35. Select Adjust Teaming configuration to display the teaming configuration  
window. Note that by default, Teaming is disabled.  
36. Select Combine my network adapters (recommended) radio button to  
enable Teaming.  
37. Click Apply to enable teaming.
