and can radiate radio frequency energy and, if not installed and used in accor­dance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference, in which case the user will be required to correct
the interference at his own expense.

Notice 1

The changes or modifications not expressly approved by the party respon­sible for compliance could void the user’s authority to operate the equipment.

Notice 2

Shielded interface cables and A.C. power cord, if any, must be used in order to
comply with the emission limits.

The 850 Pro5 (MS-6545 v1.X) ATX mainboard is a high-performance
computer mainboard based on Intel® 82850 chipset. It is optimized to support
Intel® Pentium® 4 processors for high-end business/personal desktop markets.

The Intel® 850 chipset supports 64-byte cache line size and a 32-bit host
addressing, allowing the processor to access the chipset’s memory address
space. It also provides 4x AGP data transfers and AGP Fast Write capability.

The Intel® 850 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® 82801BA (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.

D-LED™ & D-Bracket™ (Optional)

The D-LED™ uses graphic signal display to help
users understand their system. Four LEDs embedded in
the mainboard provide up to 16 combinations of signals to
debug the system. The 4 LEDs can debug all problems that
fail the system, such as VGA, RAM or other failures. This
special feature is very useful for the overclocking users.
These users can use the feature to detect if there are any
problems or failures.

The D-Bracket™ which integrates four Diagnostic LEDs is optional.
Definitions of the D-Bracket™ LED signals are the same as D-LED™ as shown

Live BIOS™/Live Driver™

The Live BIOSTM is a tool used to detect and update your
BIOS online so that you don’t need to search for the correct
BIOS version through the whole web site. To use the function,
you need to install the “MSI Live Update Series” application.
After installation, the “MSI Live Update Series” icon (as the
right view) will appear on the screen.

Double click the “MSI Live Update Series” icon, and the following screen
will appear.

Four buttons are placed on the left column of the screen. Click the desired
button to start the update process.

Hardware Setup

This chapter provides you with the information about hardware setup
procedures. While doing the installation, be careful in holding the components
and follow the installation procedures. For some components, if you install in
the wrong orientation, the components will not work properly.

Use a grounded wrist strap before handling computer components. Static
electricity may damage the components.

Central Processing Unit: CPU

The mainboard supports Intel® Pentium® 4 processor in the 478 pin
package. The mainboard uses a CPU socket called PGA478 for easy CPU
installation. When you are installing the CPU, make sure the CPU has a heat
sink and a cooling fan attached on the top to prevent overheating. If you do not
find the heat sink and cooling fan, contact your dealer to purchase and install
them before turning on the computer.

1. Pull the lever sideways away

from the socket. Then, raise
the lever up to a 90-degree
angle.

2. Look for the dot/cut edge. The

dot/cut edge should point to­wards the lever pivot. The
CPU will only fit in the correct
orientation.

3. Hold the CPU down firmly,

and then close the lever to
complete the installation.

CPU Installation Procedures

Overheating will seriously damage the CPU and system,
always make sure the cooling fan can work properly to
protect the CPU from overheating.

WARNING!

Installing the CPU Fan

As processor technology pushes to faster speeds and higher
performance, thermal managment becomes increasingly important. To dissi­pate heat, you need to attach the CPU cooling fan and heatsink on top of the
CPU. Follow the instructions below to install the Heatsink/Fan:

2. Position the heatsink onto the reten-

tion mechanism.

1. Locate the CPU and its retention

mechanism on the motherboard.

3. Mount the fan on top of the heatsink.

Press down the fan until its four clips
get wedged in the holes of the reten­tion mechanism.

4. Press the two levers down to fasten

the fan. Each lever can be pressed
down in only ONE direction.

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 1 4

then CPU core speed = Host Clock x Core/Bus ratio

= 100MHz x 14
= 1.4GHz

5. Connect the fan power cable from the mounted fan to the 3-pin fan power connector

on the board.

Overclocking

This motherboard is designed to support overclocking.
However, please make sure your components are able to
tolerate such abnormal setting, while doing overclocking.
Any attempt to operate beyond product specifications is not
recommended. We do not guarantee the damages or risks

caused by inadequate operation or beyond product
specifications.

The mainboard provides 4 gold-lead sockets for 184-pin RIMM modules.
To operate properly, at least two RIMM modules must be installed. The
mainboard supports the memory size up to 2 GB.

Memory Installation

About RIMM Module

RIMM module is a module integrated with RDRAM chips. It is similar to
a DIMM package but uses different pin settings. Rambus trademarked the term
RIMM as an entire word for a module using Rambus technology.

Memory Population Rules

z Support RIMM only.
z T o operate properly, make sure that the RIMM banks are using the same

type and equal size density memory.

z Support FSB 100MHz: PC600/PC800 RIMM.

Note: PC700 will run at PC600 specification.

z Support up to 32 Direct Rambus Device.
z Support ECC Single bit Correction and Multiple bit error detection

(Setting in BIOS).

z Install two RIMM modules either on “RIMM 1and RIMM 2” or on

“RIMM3 and RIMM4” slots.

Note: If only two RIMM slots are

populated, you must install C-RIMM
(Continuity RIMM) modules on the other
unused RIMM slots. A C-RIMM module is a dummy module for continuing
the signal connection.

C-RIMM Module

1. The RIMM slot has 2 Notch

Keys, so the RIMM memory
module can only fit in one
orientation.

2. Insert the RIMM memory module

vertically into the RIMM slot.
Then push it in.

3. The plastic clips at sides of the

RIMM slot will automatically
close.

4. If you won’t insert any RIMM

modules on the other two RIMM
slots, you must install C-RIMM
modules on the empty slots.

Power Supply

ATX 20-Pin Power Connector: JWR1

This connector allows you to connect to an ATX power supply. To
connect to the ATX power supply, make sure the plugs of the power supply is
inserted in the proper orientation and the pins are aligned. Then push down
the power supply firmly into the connector. The power connector supports
instant power on function which means that system will boot up immediately
when the power supply connector is inserted on the board.
