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 Ultra. 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.

Chapter 1 Introduction
Features Summary
(Note 1) Due to standard PC architecture, a certain amount of memory is reserved for system usage
and therefore the actual memory size is less than the stated amount. For example, 4 GB of
memory size will instead be shown as 3.xxGB memory during system startup.
