Introduction
The 845 Pro (MS-6529) ATX mainboard is a high-performance
computer mainboard based on Intel®82845 & 82801BA chipsets. The 845
Pro (MS-6529) is designed for Intel®Pentium®4 processor in the 423 pin
package that delivers a high performance and professional desktop platform
solution.
The Intel®82845 Memory Controller Hub (MCH) provides the proces-
sor interface, SDRAM interface, AGP interface and hub interface. It supports:
a single processor with a data transfer rate of 400MHz, SDRAM at 133MHz
operation (PC133), AGTL+ host bus with integrated termination supporting
32-bit host addressing, 1.5V AGP interface with 4x SBA/data transfer and 2x/4x
fast write capability, and 8-bit, 66MHz 4x hub interface to the Intel ICH2.
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™
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.
If your motherboard supports and installs D-
Bracket™ which also integrates four Diagnostic LEDs, definitions of the
LED signals are the same as D-LED™ as shown below.

Live BIOS™ & Live Driver™
The Live BIOS™ & Live Driver™ is a tool used to detect
and update your BIOS and drivers online so that you don’t
need to search for the correct BIOS or drivers 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 compo-
nents 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. The mainboard
uses a CPU socket called Socket 423 for easy CPU installation. Make sure
that the CPU has a Heat Sink and a cooling fan attached to prevent
overheating. If you do not find the Heat Sink and cooling fan, contact your
dealer or purchase them before turning on the computer.
Overheating will seriously damage the CPU
and system, always make sure the cooling fan can work
properly to protect the CPU from overheating.
WARNING!
1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
2. Look for the gold arrow.
The gold arrow should point
towards the end of lever.
The CPU will only fit in the
correct orientation.
3. Hold the CPU down firmly,
and then close the lever to
complete the installation.

Installing the CPU Fan
As processor technology pushes to faster speeds and higher
performance, thermal management becomes increasingly important. To
dissipate heat, you need to attach the CPU cooling fan and heatsink on top
of the CPU. The Pentium 4 has its specific CPU fan. Unproper CPU fan may
lead to overheating problem that will damage the CPU. Therefore, make sure
you use the appropriate CPU fan. Follow the instructions below to install
the Heatsink/Fan:
2. Position the fan module onto the retention mechanism. Close the levers
to fix the attachment.
1. Open the levers of the retention mechanism.

CPU Core Speed Derivation Procedure
If CPUClock = 100MHz
Core/Bus ratio = 14
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHzx14
= 1.4GHz
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.
If you overclock the CPU FSB clock over 160MHz, the use
of PC150 or better DRAM modules is strongly
recommended.

Introduction to SDRAM
Synchronous DRAM (SDRAM) is a type of dynamic RAM memory
chip that has been widely used starting in the latter part of the 1990s. SDRAMs
are based on standard dynamic RAM chips, but have sophisticated features
that make them considerably faster. First, SDRAM chips are fast enough to be
synchronized with the CPU's clock, which eliminates wait states. Second, the
SDRAM chip is divided into two cell blocks, and data is interleaved between
the two so that while a bit in one block is being accessed, the bit in the other is
being prepared for access. This allows SDRAM to burst the second and
subsequent, contiguous characters at a rate of 10ns, compared to 60ns for the
first character.
SDRAM provides 800 MBps or 1 GBps data transfer depending on
whether the bus is 100MHz or 133MHz.

You can install one or more DIMM modules in the following
combination:
DIMM Modules Combination
DIMM Socket Memory Module Total Memory
Socket 1
(Bank 0 & Bank 1) 64MB, 128MB, 256MB, 512MB, 1GB 64MB ~ 1GB
Socket 2
(Bank 2 & Bank 3) 64MB, 128MB, 256MB, 512MB, 1GB 64MB ~ 1GB
Socket 3
(Bank 4 & Bank 5) 64MB, 128MB, 256MB, 512MB, 1GB 64MB ~ 1GB
Total System Memory 64MB ~ 3GB
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 each side of the DIMM slot will automatically
close.

Installing DIMM Modules
Note: As 845 chipset does not properly support the PC100 memory, it
is strongly recommended to install PC133 DIMM modules for the
better system performance and stability. We do not guarantee the
system stability when installing PC 100 DIMM modules.
