Hardware Setup
This chapter tells you how to install the CPU, memory modules, and expansion cards, as well as how to
setup the jumpers on the mainboard. It also provides the instructions on connecting the peripheral
devices, such as the mouse, keyboard, etc. While doing the installation, be careful in holding the
components and follow the installation procedures.
Central Processing Unit: CPU
The mainboard supports Intel Pentium 4 Northwood & Prescott Celeron 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. (For the latest information about CPU, please visit
http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_cpu_support.php )
Example of CPU Core Speed Derivation Procedure

Installing the CPU Fan
As processor technology pushes to faster speeds and higher performance, thermal management
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:
1. Locate the CPU and its retention mechanism on the motherboard.
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 fasten the fan. Each lever can be pressed down in only ONE
direction.
5. Connect the fan power cable from the mounted fan to the 3-pin fan power connector on the

Frequency/Voltage Control
Current CPU Clock
It shows the current clock of CPU. Read-only.
Adjust Memory Frequency
When it is set to [Manual] in High Performance Mode, user can place an artificial memory clock limit on
the system. Please note that memory is prevented from running faster than this frequency. Setting
options: [PC100], [PC133], [Auto].
Auto Detect PCI Clk
This item is used to auto detect the PCI slots. When set to [Enabled], the system will remove (turn off)
clocks from empty PCI slots to minimize the electromagnetic interference (EMI). Settings: [Enabled],
[Disabled].
Spread Spectrum
When the motherboard’s 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, select the desired range for EMI reduction. Remember to disable Spread
Spectrum function if you are overclocking, because even a slight jitter can introduce a temporary boost
in clock speed which may just cause your overclocked processor to lock up.
CPU Clock
This item allows you to select the CPU Front Side Bus clock frequency (in MHz) and overclock the
15
processor by adjusting the FSB clock to a higher frequency.
Adjust CPU Ratio
This item allows you to adjust the CPU ratio. Setting range is from [8] to [50].
Memory Voltage
Adjusting the DDR voltage can increase the DDR speed. However, any changes made to this setting
may cause a stability issue, so changing the DDR voltage for long-term purpose is NOT recommended.
AGP Voltage
AGP voltage is adjustable in the field, allowing you to increase the performance of your AGP display
card when overclocking, but the stability may be affected. Setting options: 1.5V to 1.8V at 0.1V
increment.
