CoreCenter

(TM)

- contains OC Menu panel, users can determine their processor and memory type to optimize its memory capacity. This all-in-one hardware console is advanced combination of the popular PC Alert and Fuzzy Logic. Including powerful function with hardware monitor, system alert and instinctive UI of overclocking, CoreCenter is just like your PC doctor that can detect, view and adjust the PC hardware and system status during real time operation.

In the left side it shows the current system status including the Vcore, 3. 3V, +5V and 12V. In the right side it shows the current PC hardware status such as the CPU & system temperatures and all fans speeds.

When you click the red triangles in the left and right sides, two submenus will open for users to overclock, overspec or to adjust the thresholds of system to send out the warning messages. If you click the Core Center button in the top, a screen pops up for you to choose the “Auto mode” or “User mode” of CPU fan.

1-7

Getting Started

Left-wing: Current system status

In the left sub-menu, you can configure the settings of FSB, Vcore, Memory Voltage and AGP Voltage by clicking the radio button in front of each item and make it available (the radio button will be lighted as yellow when selected), use the “+” and “-” buttons to adjust, then click

““

“OK

””

” to apply the

changes. Then you can click Save to save the desired FSB you just configured.

Also you may click Auto to start testing the maximal CPU overclocking value, The CPU FSB will automatically increase the testing value until the PC reboots. Or you may click Default to restore the default values.

Right-wing: PC hardware status during real time operation

In the right sub-menu, here you can configure the PC hardware status such as CPU & system temperatures and fan speeds. You may use the scroll bars to adjust each item, then click

““

“OK

””

” to apply the changes. The values you

set for the temperatures are the maximum thresholds for the system for warnings, and the value for fan speeds are the minimum thresholds.

T op-side: User mode/Auto mode

Here you may adjust the CPU fan speed. If you choose User mode, you may adjust the CPU fan speed in 8 different modes, from Stop to Full speed.

OC Menu

The exclusive OC Menu is fully developed to support DDR400+ memory modules. By comprehensive validation of over 67 DDR400+ memory modules, MSI concluded best parameters for DRAM voltage, V io and other BIOS settings. Y ou can select DDR433, DDR450, DDR466 and DDR500 from DRAM frequency in BIOS setting. Or you can just click on OC Menu button to configure in the OC Menu at CoreCenter. OC Menu will adjust the necessary parameters of voltage and frequency simultaneously. The only limitation was the margin of processor from overclocking.

CPU Thermal Protection

Aimed to prevent the CPU from overheating, MSI has developed a CPU Thermal Protection mechanism for Intel® CPU platform. This CPU Thermal Protection mechanism works on a thermal signal sensor. If the mechanism senses an abnormal temperature rise, it will automatically shut down the system and the CPU temperature will then drop down and resume normal. With this unique feature, users can better protect their CPU. Please note that this feature is for Intel® Pentium CPU only.

S-Bracket (Optional)

S-Bracket is a bracket which provides 2 SPDIF jacks for digital audio transmission and 2 analog Line-Out connectors for additional 4-channel analog audio output. With the S-Bracket, your system will be able to perform 6channel audio operation for wonderful surround sound effect, or connect to Sony & Philips Digital Interface (SPDIF) speakers for audio transmission with better quality.

The S-Bracket offers two types of SPDIF connectors: one for optical fiber and the other for coaxial connection. Select the appropriate one to meet your need. For more information on S-Bracket, refer to Appendix. Using 4- or 6-Channel Audio Function.

CPU Core Speed Derivation Procedure

If CPU Clock = 200MHz

Core/Bus ratio = 12

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

= 200MHz x 12 = 2.4 GHz

The mainboard supports Intel® Pentium® 4 processors 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 have the heat sink and cooling fan, contact your dealer to purchase and install them before turning on the computer.

MSI Reminds Y ou...

Overheating

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

Overclocking

This motherboard is designed to support overclocking. 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.

Memory

DIMM1-2

The mainboard provides 2 slots for 184-pin, 2.5V DDR DIMM modules and supports the memory size up to 2 GB without ECC,. Y ou can install DDR266/ DDR333/DDR400 DDR SDRAM modules on the DDR DIMM slots. T o operate properly, at least one DIMM module must be installed.

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. Three types of DDR are available at the time of writing: DDR266, DDR333 & DDR400. DDR266 DDR SDRAM running at 133MHz will produce about 1.6GB/s memory bandwidth. DDR333 running at 166MHz will produce 2.1GB/s memory bandwidth. DDR400 is also available with bandwidith up to 3.2GB/s for singlechannel mode or with 6.4GB/s for dual-channel mode. High memory bandwidth makes DDR an ideal solution for high performance PC, workstations and servers.

DDR DIMM Module Combination

Install at least one DIMM module on the slots. Memory modules can be installed on the slots in any order . You can install either single- or double-side modules to meet your own needs.

2-5

Hardware Setup

Installing DDR Modules

1. The DDR DIMM has only one notch on the center of module. The module

will only fit in the right orientation.

2. Insert the DIMM memory module vertically into the DIMM slot. Then

push it in until the golden finger on the memory module is deeply inserted in the socket.

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

MSI Reminds Y ou...

You can barely see the golden finger if the module is properly inserted in the socket.
