MSI 815 PRO Manual de usuario

CHAPTER 1 INTRODUCTION

1-1

The815PRO(MS-6326)ATX S2 mainboardisahigh-performance

computer mainboard based on Intel®815 chipset. The 815 PRO is optimized

to support the Intel®Pentium®III (FC-PGA) processor for high-end busi-

ness/personal desktop markets.

The Intel®815 chipset integrates a Display Cache SDRAM control-

ler that supports a 32-bit 133MHz SDRAM array for enhanced integrated 3D

graphics performance. It is a highly-flexible chipset which is designed to

extend the basic graphics/multimedia PC platform up to the mainstream

performance desktop platform.

The Intel®815 chipset implements the host address, control, and

data bus interfaces within a single device. It takes advantage of the

pipelined addressing capability of the processor to improve the overall

system performance. In addition, the chipset also integrates a system

memory controller that supports a 64-bit 100/133 MHz SDRAM array.

The Intel®82801AA (ICH) chipset is a highly integrated

multifunctional I/O Controller Hub that provides the interface to the PCI Bus

and integrates many of the functions needed in today’s PC platforms. It

communicates with the host controller over a dedicated hub interface and

provides added flexibility in designing cost-effective system solutions.

HARDWARE INSTALLATION

2.1 Central Processing Unit: CPU

The mainboard operateswith Intel®CeleronTM/Pentium®III (FC-PGA)

processor. The mainboard uses a CPU socket called Socket 370 for easy

CPU installation. The CPU should always have a Heat Sink and a cooling

fan attached to prevent overheating.

3. Press the lever down to

complete the installation.

2. Locate Pin 1 in the socket

and look for the white dot or

cut edge in the CPU. Match

Pin 1 with the white dot/cut

edge. Then, insert the CPU.

It should insert easily.

from the socket. Then, raise

the lever up to a 90-degree

angle.

2.1-1 CPU Installation Procedures

CHAPTER 2 HARDWARE INSTALLATION

2-2

The mainboard CPU Bus Frequency can be set through BIOS setup.

If CPUClock = 100MHz

Core/Bus ratio = 7

then CPU core speed = Host Clockx Core/Bus ratio

= 700MHz

2.1-3 Overclocking Jumper: SW1

Overclocking is operating a CPU/Processor beyond its specified

frequency. SW1 jumper is used for overclocking.

SW1

SW1 Function

Auto detect/Default

Set from 133MHz to 160MHz through BIOS (DRAM: PC133)

Set from 133MHz to 167MHz through BIOS (DRAM: PC100)

Note: If you used this jumper for overclocking, you also need to

modify the CPU Bus ratio through BIOS.

Set from 100MHz to 150MHz through BIOS

Set from 66MHz to 100MHz through BIOS

2.1-4 Fan Power Connectors: CPUFAN, SYSFAN &

PSFAN

These connectors support system cooling fan with + 12V. It supports

three pin head connector. When connecting the wire to the connector,

always take note that the red wire is the positive and should be con-

nected to the +12V, the black wire is Ground and should be connected to

GND. If your mainboard has System Hardware Monitor chipset on-

board, you must use a specially designed fan with speed sensor to take

advantage of this function.

For fans with fan speed sensor, every rotation of the fan will send out 2

pulses. System Hardware Monitor will count and report the fan rotation

speed.

Note: 1. Always consult vendor for proper CPU cooling fan.

2. CPU FAN supports the FAN control. You can install PC Alert

utility. This will automatically control the CPU FAN Speed according

to the actual CPU temperature.

2.2 Clear CMOS Jumper: JBAT1

A battery must be used to retain the mainboard configuration in CMOS

RAM. Short 1-2 pins of JBAT1 to store the CMOS data.

Keep Data Clear Data

Note: 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. Always unplug

the power cord from the wall socket.
