Central Processing Unit: CPU

The mainboard supports Intel® Pentium® 4 processor in the 478 pin
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.

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.

3. Hold the CPU down firmly,

and then close the lever to
complete the installation.

CPU Installation Procedures

Overheating will seriously damage the CPU and system,
always make sure the cooling fan can work properly to
protect the CPU from overheating.

WARNING!

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:

2. Position the heatsink onto the reten-

tion mechanism.

1. Locate the CPU and its retention

mechanism on the motherboard.

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 fasten

the fan. Each lever can be pressed
down in only ONE direction.

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 14

then CPU core speed = Host Clock x Core/Bus ratio

= 100MHz x 14
= 1.4GHz

5. Connect the fan power cable from the mounted fan to the 3-pin fan power connector

on the board.

The mainboard provides 3 slots for 184-pin, 2.5V DDR DIMM with 6
memory banks. Y ou can install PC1600/PC2100 DDR SDRAM modules on the
DDR DIMM slots (DDR 1~3). To operate properly, at least one DIMM module
must be installed.

DDR DIMM Slots
(DDR 1~3)

Introduction to DDR SDRAM

DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM mod­ules rather than 168-pin DIMM modules used by SDR SDRAM. Two types of
DDR are available at the time of writing: PC1600 & PC2100. PC1600 DDR SDRAM
running at 100MHz will produce about 1.6GB/s memory bandwidth. PC2100
running at 133MHz will produce 2.1GB/s memory bandwidth. High memory
bandwidth makes DDR an ideal solution for high performance PC, worksta­tions and servers.

Chapter 2

2-6

You can install either single sided or double sided 184-pin DDR DIMM
modules into DDR DIMM slots to meet your needs. Different from the SDR
DIMM, the DDR DIMM has only one notch on the center of module. The
number of pins on either side of the breaks are different. The module will only
fit in the right orientation.

Y ou can install memory modules in any combination as follows:

Spread Spectrum

When the motherboard clock generator pulses, the extreme values (spikes) of
the pulses creates EMI (Electromagnetic Interference). The Spread Spectrum
function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are reduced to flatter curves. If you do not have any EMI
problem, leave the setting at Disabled for optimal system stability and
performance. But if you are plagued by EMI, setting to Enabled for EMI
reduction. Remember to disable Spread Spectrum if you are overclocking be­cause even a slight jitter can introduce a temporary boost in clockspeed which
may just cause your overclocked processor to lock up.

About Supervisor Password & User Password:

Supervisor password: Can enter and change the settings of

the setup menu.

User password: Can only enter but do not have the right

to change the settings of the setup menu.

Supervisor/User Password

When you select this function, a message as below will appear on the screen:

Type the password, up to six characters in length, and press <Enter>. The
password typed now will replace any previously set password from CMOS
memory. You will be prompted to confirm the password. Retype the password
and press <Enter>. You may also press <Esc> to abort the selection and not
enter a password.

To clear a set password, just press <Enter> when you are prompted to enter the
password. A message will show up confirming the password will be disabled.
Once the password is disabled, the system will boot and you can enter Setup
without entering any password.

When a password has been set, you will be prompted to enter it every time you
try to enter Setup. This prevents an unauthorized person from changing any
part of your system configuration.

Additionally, when a password is enabled, you can also have AMIBIOS to
request a password each time the system is booted. This would prevent unau­thorized use of your computer. The setting to determine when the password
prompt is required is the P ASSWORD CHECK option of the ADV ANCED BIOS
FEATURES menu. If the PASSWORD CHECK option is set to Always, the
password is required both at boot and at entry to Setup. If set to Setup, pass­word prompt only occurs when you try to enter Setup.

Load High Performance/BIOS Setup Defaults

The two options on the main menu allow users to restore all of the BIOS
settings to High Performance defaults or BIOS Setup defaults. The High Per­formance Defaults are the default values set by the mainboard manufacturer
for the best system performance but probably will cause a stability issue. The
BIOS Setup Defaults are the default values also set by the mainboard manufac­turer for stable performance of the mainboard.

When you select Load High Performance Defaults, a message as below appears:

Pressing ‘Y’ loads the default BIOS values that enable the best system
performance but may lead to a stability issue.

The option is for power or overclocking users only. Use of high
performance defaults will tighten most timings to increase the sys­tem performance. Therefore, a high-end system configuration is a
must, which means you need high-quality VGA adapter, RAM and
so on. We don’t recommend that users should apply the high
performance defaults in their regular systems. Otherwise, the sys­tem may become unstable or even crash. If the system crashes or
hangs after enabling the feature, please CLEAR CMOS DATA to
resolve the problem. For more information, refer to “Clear CMOS
Jumper:JBAT1” in Chapter 2.

WARNING!

When you select Load BIOS Setup Defaults, a message as below appears:

Pressing ‘Y’ loads the default values that are factory settings for stable system
performance.
