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.

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

2.1-3 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.

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

2.3 Memory Installation
2.3-1 Memory Bank Configuration
Themainboard supports a maximum memory size of 512MB(8Mx8) or 1G
(16M x 4) registered DIMM for SDRAM: It provides four 168-pin
unbuffered DIMMs (Double In-Line Memory Module) sockets. It supports
8 MB to 256 Mbytes DIMM memory module.
DIMM1(Bank0+Bank1)
DIMM2(Bank2+Bank3)
DIMM3(Bank4+Bank5)
There are three kinds of DIMM specification supported
by this mainboard: PC133, PC100 and PC66. If you
use 66MHz CPU Bus Frequency, these four DIMM
Specs. is supported. If you use 100 MHz CPU Bus
Frequency, only PC100 DIMM Specs. is supported.If
you use 133 MHz CPU Bus Frequency, only PC133
DIMM Specs. is supported.

A. HowtoinstallaDIMMModule
1. The DIMM slot has 2 Notch Keys “VOLT and DRAM”, so the
DIMM memory module can only fit in one direction.
2. Insert the DIMM memory module vertically into the DIMM slot.
Then push it in.
3. The plastic clip at the side of the DIMM slot will automatically
close.
