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.

1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree

• 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.

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.

• 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.
