INTRODUCTION
The MS-6339 ATX TH1 mainboard is a high-performance computer
mainboard based on Intel® 2 50 chipset. The MS-6339 is optimized to
support the Intel® Pentium® 4 processor for high-end business/personal
desktop markets.
The Intel® Tehama chipset supports 64B cache line size and a 32-bit
host addressing, allowing the processor to access the entire 4GB of the
chipsets memory address space. It also provides 4x AGP data transfers and
2x/4x AGP Fast Writes capability. Including a 3.2GBs memory bus bandwidth
and 3.2GBs system bus bandwidth.
The Intel® Tehama chipset features a dual channel Direct RDRAM
memory operating in lock-step using RSL technology. 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® 2 01BA (ICH2) 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
Central Processing Unit: CPU
The mainboard operates with Intel® Pentium® 4 processor. The mainboard
uses a CPU socket called Socket 423 for easy CPU installation. The CPU
should always have a eat 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.

• CPU Core Speed Derivation Procedure
The mainboard CPU Bus Frequency can be set through BIOS setup.
If CPU Clock = 100M z
Core/Bus ratio = 14
then CPU core speed = ost Clock x Core/Bus ratio
= 1.4G z

• Fan Power Connectors: CPUFAN/PSFAN/SYSFAN
These connectors support system cooling fan with + 12V. It sup-
ports 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 ard-
ware 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 ardware Monitor will count and report the fan rotation
speed.
Note: Always consult vendor for proper CPU cooling fan.

• Memory Installation Procedures
A. How to install a IMM Module
1. The RIMM slot has 2 Notch Keys, so the RIMM memory module
can only fit in one direction.
2. Insert the RIMM memory module vertically into theRIMM slot.
Then push it in.
3. The plastic clip at the side of the RIMM slot will automatically
close.

Power Switch
Connect to a 2-pin push button switch. This switch has the same feature
with JRMS1.
Reset Switch
Reset switch is used to reboot the system rather than turning the power ON/
OFF. Avoid rebooting while the DD LED is lit. You can connect the Reset
switch from the system case to this pin.
Power LED
The Power LED is lit while the system power is on. Connect the Power LED
from the system case to this pin. There are two types of LED that you can
use: 3-pin single color LED or 2-pin dual color LED (ACPI request).
a. 3 pin single color LED connect to pin 4, 5, & 6. This LED will lit
when the system is on.
b. 2 pin dual color LED connect to pin 5 & 6.
G EEN Color: Indicate the system is in full on mode.
O ANGE Color: Indicate the system is in suspend mode.
Speaker
Speaker from the system case is connected to this pin.
If on-board Buzzer is available:
Short pin 14-15: On-board Buzzer Enabled.
Open pin 14-15: On-board Buzzer Disabled.
HDD LED
DD LED shows the activity of a hard disk drive. Avoid turning the power
off while the DD led is lit. You can connect the DD LED from the system
case to this pin.
Keylock (reserved)
Keylock allows you to disable the keyboard for security purposes. You can
connect the keylock to this pin.
