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, Memory, Cards….etc.

- 9 - Hardware Installation Process
English
To set up your computer, you must complete the following steps:
Step 1- Install the Central Processing Unit (CPU)
Step 2- Install memory modules
Step 3- Install expansion cards
Step 4- Install I/O Peripherals cables
Hardware Installation Process
Step 1: Install the Central Processing Unit (CPU)
Before installing the CPU, please comply with the following conditions:
1. Please make sure that the motherboard supports the CPU.
2. Please take note of the one indented corner of the CPU. If you install the CPU
in the wrong direction, the CPU will not insert properly. If this occurs, please change
the insert direction of the CPU.
3. Please add an even layer of heat sink paste between the CPU and heatsink.
4. Please make sure the heatsink is installed on the CPU prior to system use, otherwise
overheating and permanent damage of the CPU may occur.
5. Please set the CPU host frequency in accordance with the processor specifications. It
is not recommended that the system bus frequency be set beyond hardware specifica
tions since it does not meet the required standards for the peripherals. If you wish to set
the frequency beyond the proper specifications, please do so according to your hard
ware specifications including the CPU, graphics card, memory, hard drive, etc.
HT functionality requirement content :
Enabling the functionality of Hyper-Threading Technology for your computer system re-
quires all of the following platform components:
- CPU: An Intel®Pentium 4 Processor with HT Technology
- Chipset: An Intel®Chipset that supports HT Technology
- BIOS: A BIOS that supports HT Technology and has it enabled
- OS: An operation system that has optimizations for HT Technology

Step 1-1: CPU Installation
Figure 1.
Pull the rod to the 90-degree directly.
Figure 2.
Locate Pin 1 in the socket and look for a (golden) cut edge on the
CPU upper corner. Insert the CPU into the socket. (Do not force the
CPU into the socket.) Then move the socket lever to the locked
position while holding pressure on the center of the CPU.
Step 1-2: CPU Cooling Fan Installation
Figure 1.
Apply the thermal tape(or grease) to provide better heat conduction
between your CPU and cooling fan.
Figure 2.
Fasten the cooling fan supporting-base onto the CPU socket on the
motherboard.

Make sure the CPU fan is plugged to the CPU fan connector, and
then the installation is completed.

Step 2: Install Memory Modules
Before installing the memory modules, please comply with the following conditions:
1. Please make sure that the memory used is supported by the motherboard. It is recom-
mended that memory of similar capacity, specifications and brand be used.
2. Before installing or removing memory modules, please make sure that the computer
power is switched off to prevent hardware damage.
3. Memory modules have a foolproof insertion design. A memory module can be
installed in only one direction. If you are unable to insert the module, please switch the
direction.
4. Because of chipset (Intel 845PE/GE) limitations, DDR333 memory modules are supported
only when you install a Pentium 4 processor with 533MHz FSB. A Pentium 4 processor with
400MHz FSB will support DDR266 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.
DDR memory module
notch
Fig.1
The DIMM socket has a notch, so the DIMM memory module
can only fit in one direction. Insert the DIMM memory module
vertically into the DIMM socket. Then push it down.
Fig.2
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 AGP Card
1. Read the related expansion card's instruction document before installing the expansion card into
the computer.
2. Please make sure your AGP card is AGP 4X (1.5V).
3. 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.

1/2) ATX_12V/ATX (Power Connector)
With the use of the power connector, the power supply can supply enough stable power to all
the components on the motherboard. Before connecting the power connector, please make sure
that all components and devices are properly installed. Align the power connector with its
proper location on the motherboard and connect tightly.
The ATX_12V power connector mainly supplies power to the CPU. If the ATX_12V power
connector is not connected, the system will not start.
Caution!
Please use a power supply that is able to handle the system voltage requirements. It is
recommended that a power supply that can withstand high power consumption be used (300W
or greater). If a power supply is used that does not provide the required power, the result can
lead to an unstable system or a system that is unable to start.
