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.
Note: Make sure the CPU is fully seated and
level in the socket.

Hardware Installation
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 dualchannel memory, alternating slots should be populated. For example with two DIMMs,
slots 0 and 1 should be used.
CPU side
DIMM Slot 0
DIMM Slot 2

Installing and Configuring the BFG NVIDIA nForce 680i LT 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 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.

4.
Carefully place the motherboard onto the studs/spacers located inside the chassis.
Align the mounting holes with the studs/spacers.
Align the connectors to the I/O shield.
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.
