Parts NOT in the Kit
This kit contains all the hardware necessary to install and connect your new BFG
NVIDIA®nForce®680i LT SLI motherboard. However, it does not contain the following
items that must be purchased separately to make the motherboard functional.
• Intel®Socket 775 Processor:
Intel®Core™ 2 Extreme (dual and quad core), Core™ 2 Quad, Core™2 Duo, Pentium
®
EE, Pentium®D, Pentium®4, and Celeron®D Socket 775 processors
• Cooling Fan for the Processor
• System Memory:
Supports dual channel DDR2 533/667/800, and up to 800 MHz SLI-Ready Memory.
Supports up to 8 GB/s DDR2 memory with a 64-bit operating system.
• PCI Express®Graphics Card:
This motherboard is capable of using the NVIDIA SLITMtechnology. To utilize this
technology requires two SLI-capable graphics cards of the same make and model, for
example two of the BFG NVIDIA GeForce® 8800 GTX OCTM768MB PCIe. When ordering
a graphics card, be sure it is a PCI Express card. The kit does contain the SLI
connector used to connect the two graphics cards.
See Installing Graphics Cards in an
SLI Configuration located on the CD in the .pdf entitled “Using the NVIDIA Software”.
• PCI Express Compliant Power Supply:
The power supply requirement is dependent upon the power and the number of the
GPUs you install. If you are going to SLI two graphics cards, you are going to require
more power. As a rule, for one GPU you need a minimum of a 300W power supply. If
you have two GPUs in an SLI configuration, you will need a minimum of a 500W power
supply. To calculate the power you are going to require for your specific configuration,
go to www.slizone.com.
These instructions tell you how to install each of the parts listed so you can have a
functioning motherboard. As you go through the installation instructions, it is assumed
that the necessary parts have been purchased.

Hardware Installation
This section will guide you through the installation of the motherboard. The topics
covered in this section are:
• Preparing the motherboard
➢
Installing the CPU
➢
Installing the CPU fan
➢
Installing the memory DIMMs
• 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 to/from the
computer chassis.
Ground yourself by using either a grounded wrist strap or by touching a
grounded metallic object such as the system chassis or power supply before
handling components.
11
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.
1. Remove the protective socket cover on the
load plate which is used to protect the socket
when there is no CPU installed.
2. Unhook the socket lever by pushing
down
and
away
from the socket.
3. Lift 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.
NNoottee::
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.

Align notches with notches on the CPU
Installing the CPU Fan
There are many different fan types that can be used with this motherboard. Follow the
instructions that came with your 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. To take full advantage of dual-
channel memory, alternating slots should be populated. For example with two DIMMs,
slots 0 and 1 should be used.
• Four DIMMS: Install into slots 0, 1, 2, and 3.
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 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 these studs 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.
