This chapter provides you with the information about hardware setup procedures. While doing the installation, be careful in holding the components and follow the installation procedures. For some components, if you install in the wrong orientation, the components will not work properly.
Use a grounded wrist strap before handling computer components. Static electricity may damage the components.

Central Processing Unit: CPU
The mainboard supports Intel® Pentium® 4 processor in FC-PGA2 package. The mainboard uses a CPU socket called PGA478 for easy CPU installation. When you are installing the CPU, make sure the CPU has a heat sink and a cooling fan attached on the top to prevent overheating.
If you do not find the heat sink and cooling fan, contact your dealer to purchase and install them before turning on the computer.
CPU Installation Procedures
1.Pull the lever sideways away from the socket. Then, raise the lever up to a 90-degree angle.
2.Look for the dot/cut edge. The dot/cut edge should point towards the lever pivot. The CPU will only fit in the correct orientation.

1. Overheating
The issue of heat will seriously damage the CPU and system, always make sure the cooling fan can work properly to protect the CPU from overheating.
2. Overclocking
This motherboard is designed to support overclocking. WARNING! However, please make sure your components are able to
tolerate such abnormal setting, while doing overclocking. Any attempt to operate beyond product specifications is not recommended. We do not guarantee the damages or risks caused by inadequate operation or beyond product specifications.

Chapter 2
Installing the CPU Fan
As processor technology pushes to faster speeds and higher performance, thermal managment becomes increasingly important. To dissipate heat, you need to attach the CPU cooling fan and heatsink on top of the CPU. Follow the instructions below to install the heatsink/ fan.
NOTE: The figures in this section are for reference only. Actual mainboard layout may be different from the one you purchased.
1.Locate the CPU and its retention mechanism on the mainboard.

2. Position the heatsink onto the retention mechanism.

3.Mount the fan on top of the heatsink. Press down the fan until its four clips get wedged in the holes of the retention mechanism.
4. Press the two levers down to |

Memory Installation
Memory Bank Configuration
The mainboard supports a maximum memory size of 3GB. It provides three 168-pin unbuffered SDRAM DIMM (Double In-Line Memory Module) sockets and supports 64MB to 512MB technology.
DIMM 1 ~ 3
Synchronous DRAM is a type of dynamic RAM memory chip that has been widely used starting in the latter part of the 1990s. SDRAMs are based on standard dynamic RAM chips, but have sophisticated features that make them considerably faster. First, SDRAM chips are fast enough to be synchronized with the CPU's clock, which eliminates wait states. Second, the SDRAM chip is divided into two cell blocks, and data is interleaved between the two so that while a bit in one block is being accessed, the bit in the other is being prepared for access. This allows SDRAM to burst the second and subsequent, contiguous characters at a rate of 10ns, compared to 60ns for the first character.
SDRAM provides 800 MBps or 1 GBps data transfer depending on whether the bus is 100MHz or 133MHz.

||
|

Total System Memory |
64MB ~ 3GB |
||
Note: As 845 chipset does not properly support the PC100 memory, it is strongly recommended to install PC133 DIMMs for the better system performance and stability. We do not guarantee the system stability when installing PC100 DIMMs.
Installing DIMM Modules
1.The DIMM slot has 2 Notch Keys “VOLT and DRAM”, so the DIMM memory module can only fit in one direction.

2.Insert the DIMM memory module vertically into the DIMM slot. Then push it in.

3.The plastic clip at the side of the DIMM slot will automatically close.

Power Supply
The mainboard supports ATX power supply for the power system. Before inserting the power supply connector, always make sure that all components are installed properly to ensure that no damage will be caused.
ATX 20-Pin Power Connector
This connector allows you to connect to an ATX power supply. To connect to the ATX power supply, make sure the plugs of the power supply is inserted in the proper orientation and the pins are aligned. Then push down the power supply firmly into the connector. The power connector supports instant power on function which means that system will boot up immediately when the power supply connector is inserted on the board.
ATX 12V Power Connector: JPW1
This 12V power connector is used to provide power to the CPU.
