Item Checklist
English
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.
WARNING!
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.

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, Chipsets,
SDRAM, Cards...tc.

socket. The DIMM module can only fit in one direction due to the notch. Memory size can vary
between sockets.
Support Unbuffered DDR DIMM Sizes type:
64 Mbit (2Mx8x4 banks) 64 Mbit (1Mx16x4 banks) 128 Mbit (4Mx8x4 banks)
128 Mbit (2Mx16x4 banks) 256 Mbit (8Mx8x4 banks) 256 Mbit (4Mx16x4 banks)
512 Mbit (16Mx8x4 banks) 512 Mbit (8Mx16x4 banks)
The motherboard has 3 dual inline memory module (DIMM) sockets. The BIOS will automatically
DDR
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.
0 Reverse the installation steps when you wish to
remove the DIMM module.
00
0 When RAM_LED is ON, you do not install / remove DDR from socket.
00
00
0 Please note that the DIMM module can only fit in one direction due to the two
00
notches. Wrong orientation will cause improper installation. Please change
the insert orientation.
When using double sided DDR266 modules, only a maximum of 2 sockets
can be populated. The 3rd socket has to be free.

DDR Introduction
Established on the existing SDRAM industry infrastructure, DDR (Double Data Rate) memory is
a high performance and cost-effective solution that allows easy adoption for memory vendors, OEMs
and system integrators.
DDR memory is a sensible evolutionary solution for the PC industry that builds on the existing
SDRAM infrastructure, yet makes awesome advances in solving the system performance bottleneck
by doubling the memory bandwidth. DDR SDRAM will offer a superior solution and migration path from
existing SDRAM designs due to its availability, pricing and overall market support. PC2100 DDR
memory (DDR266) doubles the data rate through reading and writing at both the rising and falling edge
of the clock, achieving data bandwidth 2X greater than PC133 when running with the same DRAM
clock frequency. With peak bandwidth of 2.1GB per second, DDR memory enables system OEMs to
build high performance and low latency DRAM subsystems that are suitable for servers, workstations,
high-end PC's and value desktop SMA systems. With a core voltage of only 2.5 Volts compared to
conventional SDRAM's 3.3 volts, DDR memory is a compelling solution for small form factor desktops
and notebook applications.
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, necessary 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.
English
AGP Card
Please carefully pull out the small whitedrawable 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 whitedrawable bar.
