When you installing AGP card, please make sure the following notice is fully understood and
practiced. If your AGP card has "AGP 4X/8X (1.5V) notch" (show below), please make sure
your AGP card is AGP 4X/8X.
Caution: AGP 2X card is not supported by nVIDIA®nForce3TM 250. You might
experience system unable to boot up normally. Please insert an AGP 4X/8X card.

Prepare your computer...
Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To
protect them against damage from static electricity, you should follow some precautions whenever you
work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do not have one,
touch both of your hands to a safely grounded object or to a metal object, such as the power
supply case.
3. Hold components by the edges and try not touch the IC chips, leads or connectors, or other
components.
4. Place components on a grounded antistatic pad or on the bag that came with the components
whenever the components are separated from the system.
5. Ensure that the ATX power supply is switched off before you plug in or remove the ATX power
connector on the motherboard.
Installing the motherboard to the chassis...
If the motherboard has mounting holes, but they don't line up with the holes on the base and there
are no slots to attach the spacers, do not become alarmed you can still attach the spacers to the
mounting holes. Just cut the bottom portion of the spacers (the spacer may be a little hard to cut off, so
be careful of your hands). In this way you can still attach the motherboard to the base without worrying
about short circuits. Sometimes you may need to use the plastic springs to isolate the screw from the
motherboard PCB surface, because the circuit wire may be near by the hole. Be careful, don't let the
screw contact any printed circuit write or parts on the PCB that are near the fixing hole, otherwise it
may damage the board or cause board malfunctioning.

Step 1: Install the Central Processing Unit (CPU)
The installation of the processor and cooling fan is performed in four main steps:
Before installing the processor and cooling fan, adhere to the following warning:
1. Please make sure the CPU type is supported by the motherboard.
2. The processor will overheat without the heatsink and/or fan, resulting in permanent
irreparable damage.
3. If you do not match the CPU socket Pin 1 and CPU cut edge well, it will cause improper
installation. Please change the insert orientation.
4. Apply thermal grease between the processor and cooling fan.
5. Never run the processor without the heatsink properly and firmly attached. Permanent
damage will result.
6. Please set the CPU host frequency in accordance with your processor's specifications.
We don't recommend you to set the system bus frequency over the CPU's specification
because these specific bus frequencies are not the standard specifications for CPU,
chipset and most of the peripherals. Whether your system can run under these specific
bus frequencies properly will depend on your hardware configurations, including CPU,
Memory, Cards…etc.
Step1-1. First, check the processor pins to see that none are bent. Move the socket lever to the
unlocked position as shown in Figure 1.(90oto the plane of the motherboard) prior to inserting
the processor. The pin 1 location is designated on the processor by a copper triangle that
matches up to a triangle on the socket as shown in Figure 2. Align the processor to the socket
and gently lower it into place. Do not force the processor into the socket.
Socket Lever

Pull the lever to the 90-degree directly.
Figure 2.
Pin 1 location on the Socket and Processor. Move the
socket lever to the locked position while holding pressure
on the center of the processor.

Step1-2. When the processor is installed in the socket, apply thermal grease to the processor(as shown
in Figure 3) prior to installing the heatsink. Phase change materials develop strong adhesive
forces between the heatsink and processor. Removing the heatsink under such condi-
tions can cause the processor to be removed from the socket without moving the
socket lever to the unlocked position and then damage the processor pins or socket
contacts.
** We recommend you to apply the thermal tape to provide better heat conduction between
your CPU and heatsink. (The CPU cooling fan might stick to the CPU due to the hardening of
the thermal paste. During this condition if you try to remove the cooling fan, you might pull the
processor out of the CPU socket alone with the cooling fan, and might damage the processor.
To avoid this from happening, we suggest you to either use thermal tape instead of thermal
paste, orremove the cooling fan with extreme caution.)
Figure 3.
Application of thermal grease to the processor.
Step 1-4. Connect the fan power wires to the header on the motherboard as shown in Figure 6.
Figure 6.
Connecting the fan power wires.
Step 1-3.Once the thermal grease has been applied to the processor, the heatsink can be attached to
the processor. Align the heatsink assembly with the support frame mating with the backer plate
standoffs as shown in Figure 4 & 5.

Before installing the memory modules, adhere to the following warning:
1. When RAM LED is ON, do not install / remove DIMM from socket.
2. Please note that the DIMM module can only fit in one direction due to
the notch. Wrong orientation will cause improper installation. Please
change the insert orientation.
Step 2: Install Memory Modules
The motherboard has 3 dual inline memory module (DIMM) sockets. The BIOS will automatically
detects memory type and size. To install the memory module, just push it vertically into the DIMM
socket. The DIMM module can only fit in one direction due to the notch. Memory size can vary
between sockets.
1. The DIMM socket has a notch, so the DIMM memory
module can only fit in one direction.
2. Insert the DIMM memory module vertically into the DIMM
socket. Then push it down.
3. Close the plastic clip at both edges of the DIMM sockets
to lock the DIMM module.
Reverse the installation steps when you wish to remove
the DIMM module.

Step 3: Install Expansion Cards
1. Read the related expansion card's instruction document before install the expansion card into the
computer.
2. Remove your computer's chassis cover, screws and slot bracket from the computer.
3. Press the expansion card firmly into expansion slot in motherboard.
4. Be sure the metal contacts on the card are indeed seated in the slot.
5. Replace the screw to secure the slot bracket of the expansion card.
6. Replace your computer's chassis cover.
7. Power on the computer, if necessary, setup BIOS utility of expansion card from BIOS.
8. Install related driver from the operating system.
AGP Card
Please carefully pull out the small white-drawable bar at the end of the AGP slot when you try to install
/ uninstall the AGP card. Please align the AGP card to the onboard AGP slot and press firmly down on
the slot. Make sure your AGP card is locked by the small white-drawable bar.
When an AGP 2X (3.3V) card is installed the 2X_DET will light up, indicating a non-supported
graphics card is inserted. Informing users that system might not boot up normally due to AGP
2X (3.3V) is not supported by the chipset.
