Preparing 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.

Before i nstalling the p rocess or, adh ere to the following warning:
1. Pleas e m ake sure the CPU type i s supp orted by the m otherboard.
2. The p rocess or will over heat without the he atsink an d/or fan, resul ting i n perm anent
irreparable dam age.
3. If you do not match the CP U socke t Pin 1 and CPU cut edge well, it will caus e im proper
installation. Please change the in sert orientation.
4. Apply therma l grea se between the proce ssor a nd cooling fan.
5. Never run the pro cessor without the he atsink p roperl y and firmly attached . Perm anent
dam age will resul t.
6. Pleas e set the CPU hos t frequency in accorda nce with your pr ocessor 's spe cifications.
We don' t recomm end you to set the system bus frequency over the CPU's specification
becau se these specific bus frequenc ies are no t the standard specifica tions for CPU,
chipset and mos t of the periphe rals. Wh ether your s ystem ca n ru n under these specific
bus freq uencies pr operly will depe nd on your hardware configura tions, includ ing CP U,
Me mo ry, Card s… etc.

socket. The DIM M m odule can only fit in one direction due to the notch. Mem ory size c an vary between
soc ke ts.
Before i nstalling the m emory modules, adhere to the following warning:
1. Please note that the DIMM m odule can onl y fit in one di rection due to the one notch.
Wrong o rientation will cause im proper installation. Please change the insert orientation.
2. Due to (Intel 845PE/ GE) chipset archi tecture limi tation, a FSB 533 Pentium 4 pr ocessor
will sup port D DR333/ DDR266 me mor y m odule. A FSB 40 0 Pentium 4 processor will
onl y support DDR2 66 me mory modu le.

1. The DIMM sock et has a notch, so the DIM M
me mor y mo dule can o nly fit in one d irection.
2. Insert the DIMM m em ory m odule ver tically in to
the DIM M soc ket. The n pus h i t down.
3. Close the pl astic c lip at both e dges of the DIMM
sockets to lo ck the DIMM m odule.

Step 3: Install AGP Card
1. Read the relateAGP card's instruction document before install the AGP card into the computer.
2. If your AG P card has "AGP 4X (1.5V) notch" (show below), please ma ke sure your AGP c ard is AGP
4X(1.5V).
3. Plea se car efully pull out the small white- drawabl e bar at the end of the AG P slot when you try to
install/ U ninstall the AGP ca rd. Ple ase alig n the AGP card to the onboard AGP slot and pr ess firm ly
