Hardware Setup

If your motherboard has already been installed in your computer you may still need
to refer to this chapter if you plan to upgrade your system's hardware.

This motherboard is electrostatic sensitive. Do not touch without
wearing proper safety gadget and make sure to disconnect the power
cable from the power source before performing any work on your
motherboard. Not doing so may result in electrical shock!

2-1 Installing a CPU Processor for Socket 478

The Intel® Socket 478, designed for the Pentium 4 processor, has been incorporated
as a standard motherboard specification. To insert your CPU into Socket 478 please
follow the steps bellow:

1. Locate the 478-pin CPU socket on the motherboard.
2. Unlock the socket by pressing the leaver sideways, and then open it up to a

90-degree angle.

3. Locate a Gold Mark on the top surface of the CPU, which is close to one of the

CPU corners. The same corner will also be cut off, leaving a noticeable notch in
the CPU's corner. These markings indicate Pin 1 on the CPU.

4. Gently insert the CPU with Gold Mark/Pin 1 at the same corner of Socket 478,

which is located close to the end of the lever. Allow the weight of the CPU to
push itself into place. Do not apply extra pressure as doing so may result in
damaging your CPU.

5. When the CPU is correctly inserted, close the leaver with your finger on to of the

CPU to make sure the CPU is properly embedded into the socket.

6. Insert an appropriate heat sink and fan for proper Heat dispatch.

Installing a standard Intel® specified heat sink with cooling fan is
necessary for proper heat dissipation from your CPU. Failing to install
these items may result in overheating and possible burn-out of your CPU.

2-2 Setting Your CPU’s Performance

Frequency Configuration:

This motherboard uses a new user-friendly technology that enables the user to setup
a main board’s CPU parameters through an easy to use BIOS setup procedure. It is
no longer necessary to make many jumper settings as on conventional motherboard.
After installing all your hardware into your PC system, you can manually configure
your CPU clock ratio and CPU clock according to your processor’s specifications.

Chapter 2

By turning on your system’s power. Enable the CMOS Setup Utility by pressing the
delete key when your BIOS identification screen appears, then go to the Frequency/
Voltage control option and select your CPU clock ration and CPU clock speed
(please refer to Chapter3 for more details).

You do not need to make voltage settings because this board will automatically
set your CPU voltage.

2-3 Main Memory Configuration

The SDRAM memory system consists two banks and can support the memory size
up to 1 GB per DIMM. If you only use one bank it does not matter which one you
use and if you use two or more banks, it does not matter which bank you install first.

DRAM Specifications

DIMM type: 3.3V, 64/72-bit 168 pin SDRAM.
Module size: Single/double-sided 32/64/128/256/512 Mbytes or 1GBytes.
Parity: Ether parity or non-parity.
