1. Attach the CPU and heatsink using silica gel to ensure full contact.
2. It is suggested to select high-quality, certified fans in order to avoid
damage to the motherboard and CPU due high temperature.
3. Never turn on the machine if the CPU fan is not properly installed.
4. Ensure that the DC power supply is turned off before inserting or re
moving expansion cards or other peripherals, especially when you
insert or remove a memory module. Failure to switch off the DC
power supply may result in serious damage to your system or memory
module.
Warning:
We cannot guarantee that your system will operate normally while
over-clocked. Normal operation depends on the over-clock capacity
of your device.
Note:
Since BIOS programs are upgraded from time to time, the BIOS
description in this manual is just for reference. We do not guarantee
that the content of this manual will remain consistent with the actual BIOS version at any given time in the future.
Note:
The pictures of objects used in this manual are just for your reference.
Please refer to the physical motherboard.
This chapter introduces the hardware installation process,
including the installation of the CPU and memory. It also
addresses the connection of your power supply, use of
the rear panel connectors, connection of hard drive and
floppy drive data cables, and setting up various other
feature of the motherboard. Caution should be exercised
during the installation process. Please refer to the
motherboard layout prior to any installation and read the
contents in this chapter carefully.
Take note of the following precautions before you install components or change settings.
1. Use a grounded wrist strap or touch a safely grounded object,
such as an attached power supply, before handling components
to avoid damaging them due to static electricity.
2. Unplug the power cord before opening your chassis or touching
any component.
3. Hold components by their edges to avoid touching any exposed
integrated circuits (ICs).
4. Whenever you uninstall a component, place it on a grounded
anti-static pad or into the anti-static bag that it came in.
This motherboard accepts Intel socket 478 processors (CPUs) with a front side
bus (FSB) of 400/533/800 MHz Processors with Hyper-Threading technology
are supported.
Attention:
The CPU pins must be properly aligned with the holes in the
socket, otherwise the CPU may be damaged.
Installation of CPU
Follow these steps to install the CPU.
1. Unlock the socket by pressing the lever sideways, then lift it up to a 90
o
angle.
2. Align the cut edge to the gap in the
base of the socket. Carefully insert
the CPU into the socket until it fits in
place.
3. When the CPU is in place, press it
firmly on the socket while you push
down the socket lever to secure the
CPU. The lever clicks on the side tab
to indicate that it is locked.
New technology allows processors to run at higher and higher frequencies.
To avoid problems arising from high-speed operation, for example,
overheating, you need to install the proper fan. The following procedure is
provided for reference only, please refer to your CPU fan user guide for the
actual procedure.
1.Locate the CPU retention mechanism
base (surrounds the CPU socket).
3. Attach the fan to the base.
2.If required, apply a light coating of
silica gel to the top of the CPU.
NOTE: The CPU heatsink may have
a pre-applied thermal compound. In
that case, the silica gel is not required.
4.Connect the fan’s power cable
to the appropriate 3-pin terminal
on the motherboard.
Warning:
Excessive temperatures will severely damage the CPU and
system. Therefore, make sure that the cooling fan works normally at all times in order to prevent overheating and damaging
to the CPU.
1.Position the fan with the retention mechanism on top of the
heatsink. Align and snap the four hooks of the retention mechanism to the holes on each corner of the module base.
2.Make sure that the fan and retention mechanism assembly
perfectly fits the headtsink and module base, otherwise you
cannot snap the hooks into the holes.

Warning:
Keep the retention locks lifted upward while fitting the retention
mechanism to the module base.
This motherboard includes four 184-pin slots with 2.6V Double Data Rate
(DDR) Dual Inline Memory Module (DIMM) sockets, so you can install PC3200/
2700/2100 memory. You must install at least one memory bank to ensure
normal operation.
DIMM1
DIMM2
DIMM3
DIMM4
DDR Memory
The DDR SDRAM technology evolved from the mainstream PC66, PC100,
PC133 memory known as Single Data Rate (SDR) SDRAM. DDR memory,
however, has the ability to perform two data operations in one clock cycle,
thus providing twice the throughput of SDR memory.
A DDR DIMM has the same physical dimensions as an SDR DIMM, but it
has a 184-pin footprint compared to the 168-pin of the SDR DIMM. Also, a
DDR DIMM is single notched while an SDR DIMM is double notched.
Therefore, a DDR DIMM is not backward compatible with SDR, and should
be installed only in a socket specially designed for DDR DIMMs.
4. Make sure that the memory frequency matches the CPU FSB (Front Side
Bus). Refer to the following table.
CPU FSBDDR DIMM TypeMemory Frequency
800 MHzPC3200/PC2700/PC2100 400/333/266 MHz
533 MHzPC2700/PC2100333/266 MHz
400 MHzPC2100266 MHz
Note:
1. When using 800MHz CPU FSB,PC2700DDR DIMMs may
run only at 320MHz(not 333MHz) due to chipset limitation.
2.The following FSB/DDR ratios are not supported:400/333,
400/400,533/400.
3. FSB/DDR setting 800/333 is recognized as FSB/DDR 800/
320.
5. DIMMs installed into any three sockets will function in single Channel
mode.
6. When all four sockets are populated with 1GB DIMMs (total 4GB), the
system may detect over 3GB (a little less than 4GB) to ICH5R resource
allocation.
7. Double-sided DDR DIMMs with X16 (databus width=16-bit) memory chips
are not supported due to chipset limitations.
8. lt is recommended to use the yellow DIMM slots first.
This motherboard uses an ATX power supply. In order to avoid damaging any
devices, make sure that they have been installed properly prior to connecting the power supply.
ATX 12V Power Connector: CN11
The 4 pin ATX 12V power supply connects to CN11 and provides power to the
CPU.
ATX Power Connector: CN25
CN25 is the ATX power supply connector. Make sure that the power supply
cable and pins are properly aligned with the connector on the motherboard.
Firmly plug the power supply cable into the connector and make sure it is
secure.
