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, Memory, Cards….etc.

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

Step 1
Step 4
Step 3
Step 1: Install the Central Processing Unit (CPU)
Before installing the processor, adhere to the following warning:
1. Please make sure the CPU type is supported by the motherboard.
2. The processor will overheat without the heatsink and/or fan, resulting in permanent
irreparable damage.
3. If you do not match the CPU socket Pin 1 and CPU cut edge well, it will cause improper
installation. Please change the insert orientation.
4. Apply thermal grease between the processor and cooling fan.
5. Never run the processor without the heatsink properly and firmly attached. Permanent
damage will result.
6. 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,
Memory, Cards…etc.
HT functionality requirement content :
Enabling the functionality of Hyper-Threading Technology for your computer system
requires all of the following platform components:
- CPU: An Intel®Pentium 4 Processor with HT Technology
- Chipset: A SiS®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.

Step 2: Install memory modules
DDR
SupportUnbuffered DDR DIMM Sizes type:
64Mbit (2Mx8x4 banks) 64 Mbit (1Mx16x4 banks) 128Mbit(4Mx8x4 banks)
128Mbit(2Mx16x4 banks) 256Mbit(8Mx8x4banks) 256Mbit(4Mx16x4 banks)
512Mbit(16Mx8x4 banks) 512Mbit(8Mx16x4banks)
Notch
Before installing the memory modules, adhere to the following warning:
Please note that the DIMM module can only fit in one direction due to the one notch. Wrong
orientation will cause improper installation. Please change the insert orientation.
The motherboard has 2 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.
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.
Reverse the installation steps when you wish to
remove the DIMM module.

Step 3: Install expansion cards
1. Read the related expansion card's instruction document before install the expansion card into
the computer.
2. Please make sure your AGP card is AGP 4X/8X (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.
