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.

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.

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, contigu-

ous 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.

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.

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.

Jumpers

The mainboard provides the following jumpers for you to set the

computer’s function. This section will mention how to change your

mainboard’s function through the use of jumpers.

Clear CMOS Jumper: JBAT1

There is a CMOS RAM on board that has a power supply from

external battery to keep the data of system configuration. With the CMOS

RAM, the system can automatically boot OS every time you turn on the

computer. If you want to clear the system configuration, you can use the

JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instructions be-

low to operate:

Clear Data

Keep Data

(default)

JBAT1

You can clear CMOS by shorting 2-3 pin while the system

is off. Then return to 1-2 pin position. Avoid clearing the

CMOS while the system is on; it will damage the mainboard.

The AGP slot allows you to insert the AGP graphics card. AGP is

an interface specification designed for the throughput demands of 3D

graphics. It introduces a 66MHz, 32-bit channel for the graphics con-

troller to directly access main memory and provides three levels of

throughputs: 1x (266Mbps), 2x (533Mbps) and 4x (1.07Gbps).

PCI Slots

The five PCI slots allow you to insert the expansion cards to meet

your needs. When adding or removing expansion cards, make sure that

you unplug the power supply first. Meanwhile, read the documentation

for the expansion card to make any necessary hardware or software

settings for the expansion card, such as jumpers, switches or BIOS

configuration.
