2-1.2 CPU Installation with Socket 462
This mainboard is built with CPU Socket 462 supporting the AMD CPUs
Athlon, Athlon XP and Duron:
• Follow the steps described in this section to install CPU into the on-
board Socket 462.
• After installation of CPU, you must also install a proper cooling fan
on top of the CPU and connect the Fan cable to the CPU fan
connector.
1. First pull sideways the lever of
Socket 462, and then turn it up
900 so as to raise the upper layer
of the socket from the lower
platform.
3. Make sure that all CPU pins have
completely entered the socket
and then lower down the lever
to lock up CPU to socket.
2. Configure Pin 1 of CPU to Pin 1
of the Socket, just as the way
shown in the diagram on the
right. Adjust the position of CPU
until you can feel all CPU pins
get into the pin holes of the
socket.

2-2 Memory Installation
How to tackle the memory Modules:
• Make sure to unplug your power supply before adding or removing
memory module. Failure to do so may cause severe damage to both
your mainboard and the memory module.
• Pay attention to the orientation of the DIMM slots. Forcing a DIMM
into a slot improperly will damage the memory module and slot itself.
• Make sure you have the right type of memory module for your
mainboard.
• This series supports up to 3GB unbuffered DDR333/266 SDRAM,
with 3 DDR DIMM slots on board. Do not insert other type of mod-
ules into these slots.
• The nFORCE2 dual memory controller can double the DDR memory
bandwidth up to 6.4GB/s with DDR400, 5.4GB/s with DDR333 and
4.2GB/s with DDR266.
• To enable Dual-channel memory function, please see Dual-channel
Configuration” on next page.
• DDR DIMM slot has 184-pins and one notch. Insert a DDR SDRAM
vertically into the 184-pin slot with the notch-to-rib matching.

2-2.2 Dual-channel DDR DIMM configuration
1. To enable Dual-channel function on this series of mainboard, a DDR
SDRAM module must be first inserted into DIM3, the Master Dual-
channel slot.
2. Next, either DIM1 or DIM2 or both should be inserted with DDR
SDRAM module(s) to activate the Dual-channel function. That is, DIM3
is the Master Dual-channel slot and at least one more slot is needed
to couple the Dual-channel function.
3. If Dual-channel configuration is set up, nFORCE2 dual memory con-
troller can double the DDR memory bandwidth up to 6.4GB/s with
DDR400, 5.4GB/s with DDR333 and 4.2GB/s with DDR266.
2-2.3 o remove a DDR DIMM
First power off the system and press down the holding latches on both
sides of DIMM slot to release the module..

2-8.2 Jp2: CPU Clock Select
2. Setting Jp2 1-2 closed is for 100/133MHz CPU.
3. Setting Jp2 2-3 closed is for 166/200MHz CPU. If you want to do
overclocking with your onboard CPU, you should start system first
and then enter Advanced Chipset Features” of the BIOS Setup to
try CPU overclocking. If an overclock fails to reboot system, you
should execute the nVIDIA-Boot-Failure-Restart Procedure to reboot
system.
1. Before setting the CPU clock by Jp2, read the Identification Legend
on the CPU, find the Max FSB and divide it by two. The result is the
default CPU clock on the CPU you are using.

If a pin-header (of 2 or more pins) is
designed in such a way that its pins
can be closed or linked together to
set up a specific function, this header
is called a jumper in this manual.
A 3-pin Jumper
The conductor inside the cap
links two header-pins together.
• A Jumper is usually but not necessarily given a JpX” legend.
Jp X
• Do not remove any jumper cap when power is on. Always
make sure the power is off before changing any jumper settings.
Otherwise, mainboard could be damaged.
2-8.1 How to tackle the Jumpers:
• In the Jumper setting diagram, all jumper pins covered with
black marks stand for closed pins with jumper cap.

When you have problem with rebooting your system, you can clear
CMOS data and restore it to default value. To clear CMOS with Jumper
JBAT1, please follow the steps below:
2-8.3 JBA 1: nVIDIA Clear CMOS
nVIDIA Boot-Failure-Reboot Procedures:
1. Power off system.
2. Set JBAT1 to Pin 2-3 closed.
3. After 3 or 5 seconds(allowing residue
power to fade away), return the JBAT1
setting to Pin1-2 closed.
4. To reboot the system, press down
Insert” key before pressing down
Power Button. Do not release Insert
key until you see the initial bootup
screen.

(4) Then press down Insert” key of the keyboard before pressing down
Power Button to start system. Do not release Insert Key until you can
see the initial bootup screen appear.
(5) In some overclocking cases by BIOS Setup”, if system still cannot
boot up with the above 4 steps, please remove the on-board battery
from the battery-socket and unplug the power cord as well. Keep the
battery and power cord away from system in 10 to 20 seconds so as to
make sure all power residue has faded away.
(6) After restoring the power cord and battery to system, make sure the
CPU Clock Select” Jumper is at Default Setting” and then press the
Power Button to restart system again. Please note that Step (5) will
take the place of Step (3) and (4).
(7) After starting system, users should also enter Advanced Chipset
Features” of BIOS Setup and set the FSB Frequency” to CPU De-
fault” value for a guaranteed bootup. However, user can also select a
higher CPU clock to try overclocking again.
Whenever nVIDIA system fails to boot (including overclock and non-
overclock cases), it requires a more guaranteed Reboot Procedure to
restart system.
(1) To reboot nVIDIA system, users should first power off the system.
(2) If a CPU Clock Select” Jumper is on board, restore this jumper
setting to default setting.
(3) Execute the Clear CMOS” procedures with Clear CMOS” Jumper.

2-8.4 Jp5: Anti-burn Shield (ABSII)
Jp5 is designed to enable the overheat safeguard for some CPUs which
are incorporated with a protective thermal diode. The latest AMD Athlon
XP and Duron Morgan CPUs are incorporated with such thermal diode
and can be protected by this function. Setting Jp5 1-2 closed (default
setting) will get system shutdown when the above-mentioned CPUs get
to 85oC (the default protection temperature.) Only when the CPU re-
turns to a cooler state can you restart your system.
For other CPUs that are not incorporated with a protective thermal diode,
please set Jp5 2-3 closed to disable the function because it is a vain
design now.
Reminder: If a sudden shutdown happens to your system which has
been running well for a while with an AMD Athlon XP/ Duron Morgan
CPU, this might be caused by the Overheated CPU Shutdown” design.
Please use a better CPU cooling fan and restart your system.

2-9 Other Connectors Configuration
This section lists out all connectors configurations for users’ reference.
Both Sensor and No-sensor Fan Connectors support CPU/AGP/Sys-
tem/Case cooling fan with +12V mode. When connecting the wire to
any Fan Connector, user should make sure that the red wire is for the
positive current and should be connected to pin +12V, and the black
wire is Ground and should be connected to pin GND. A Hardware Moni-
tor chipset is on board, with which user can install a Hardware Monitor
Utility and read the fan speed transmitted from the sensor fan connector.
Otherwise, user can read the fan speed from the” Smart Doc Anti-burn
Shield” CMOS BIOS.
A running fan will send out 2 electric pulses per rotation of its fan
blade to a Sensor Fan Connector which in turn will count the electric
pulses and send the information to the System Hardware Monitor. The
hardware Monitor Program will work out the fan rotation speed and dis-
play it on screen.
