HARDWARE INSTALLATION

2.1 Central Processing Unit: CPU

The mainboard operates with Intel® 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 BIOS can be used to set the CPU Host Bus Frequency Clock.

If CPUClock = 66MHz

Core/Bus ratio = 3.5

then CPU core speed = Host Clockx Core/Bus ratio

= 66MHzx3.5

= 233MHz

2.1-2 CPU Core Speed Derivation Procedure

CHAPTER 2 HARDWARE INSTALLATION

2-3

2.1-3 CPU Speed Setting: SW1/SW2

To adjust the speed of the CPU, you must know the specification of your

CPU (always ask the vendor for CPU specification). The mainboard can

auto-detect between 66, 100 or 133MHz CPU Bus Frequency.

2.1-4 Dual Processor or Single Processor Installation

IntelPentium III processor has termination circuitry for the processor’s

AGTL+ bus. In a two processor platform, each end of the bus must be

properly terminated, whether or not both processor socket locations have

processors installed. The 694DPro has implemented 2 methods to meet

Intel Design guide. Please check onboard AGTL+ bus terminator resistor

support at location (1). If there’s no onboard AGTL+ Bus Terminator

Resistor, users should get PGA 370 bus terminator card (MS-6916) from MSI

to plug into CPU 2.

2.1-5 Fan Power Connectors: CPUFAN1/CPUFAN2/SYSFAN

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 connected 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.
