Preparing the Motherboard
The motherboard shipped in the box does not contain a CPU or memory. You
need to purchase these 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
Note: Make sure the CPU is fully seated and level in the
socket.
Align notches with

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 5 for the location of the memory slots.)
qOne DIMM: Install into slot 0. You can install the DIMM into any slot,
however, slot 0 is preferred.
qTwo DIMMs: Install into either slots 0 and 1 or 2 and 3. The idea is to not
have the DIMMs in adjacent slots.
qFour DIMMS: Install into slots 0, 1, 2, and 3.

780i 3-Way SLI Motherboard
Use the following procedure to install memory DIMMs. 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. It is normally easier to secure the motherboard first.
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.

Hardware Installation
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. In most cases, it is recommended to secure the motherboard using a
minimum of nine (9) spacers.
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.

Using the
NVIDIA Software
Built upon the foundation of NVIDIA’s core motherboard and GPU
technologies, NVIDIA System Monitor and Performance Server software
utilities bring consolidated reporting and control to the desktop in seamless
fashion. Traditionally, users have been forced to endure a sequence of trial and
error attempts within the BIOS in order to customize the operation and
performance of the system to their needs. As settings are attempted, the user
must start and restart Windows several times. Fortunately, NVIDIA’s new
System Monitor and Performance Group utilities bring the same rich
functionality found in the BIOS to the user’s desktop. From a single convenient
interface, the user can adjust settings to minimize noise, optimize performance,
and maximize system stability. In addition, a wealth of system information is
readily available in a lush 3D presentation which is customizable to suit the user.

The Motherboard option showcases a wide variety of motherboard and system-wide
options and settings. The controls located in the Adjust Motherboard Timings screen
allow the bus speeds to be adjusted manually to increase performance for gaming, or
lower performance to conserve power and create a quieter user environment. The
number to the right of the slider is the new bus speed that will be applied. Adjustments
can be made by using the mouse to drag the slider. All changes will take effect
immediately after selecting Apply; however, these setting will only remain active for the
current Windows session. This will allow a user to safely return to Windows in the event
of a crash, without any 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
