CPU Installation Procedures

2. Look for the cut edge. The

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

The mainboard supports AMD® AthlonTM, Athlon XP and Duron

TM

processors. It uses a CPU socket called Socket A for easy CPU installation.

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.

As processor technology pushes to faster speeds and higher performance,
thermal management becomes increasingly crucial when building computer
systems. Maintaining the proper thermal environment is key to reliable
operation. As such, the processor must be maintained in the specified thermal
requirements. AMD recommends the use of high performance thermal inter­face material.

AMD Athlon™/Duron™ processor with a speed of 600MHz and above re­quires LARGER heatsink and fan. You also need to add thermal grease be­tween the CPU and heatsink to improve heat dissipation. Then, make sure that
the CPU and heatsink are securely fastened and in good contact with each
other. These are needed to prevent damaging the processor and ensuring
reliable operation.

You can visit AMD’s web site for more information on proper cooling: http://

www.amd.com/products/cpg/athlon/pdf/cooling_guide.pdf

WARNING! Thermal Issue for CPU

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 7

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

= 100MHz x 7
= 700MHz

CPU Clock Frequency Selection through BIOS

To set the clock frequency of the CPU installed on the motherboard,

refer to Hardware Monitor Setup of BIOS on page 3-27.

The default hardware configuration for CPU Clock Frequency is set at
100MHz. Therefore, to use a 133MHz CPU and have it run at 133MHz, you
need to adjust the CPU clock up to 133MHz by changing the CPU clock in the
BIOS Setup utility.

Replacing CPU

While replacing the CPU, always turn off the ATX
power supply or unplug the power cable of the ATX
power supply from grounded outlet first to ensure the
safety of CPU.

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.

WARNING!

DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transfering data twice per cycle. It transfers data on
both the rising and falling edges of the clock. Conventional SDRAM only
uses the rising edge of the clock to transfer data. Therefore, conventional
SDRAM is called SDR (Single Data Rate) SDRAM.

DDR SDRAM uses 2.5 volts as opposed to 3.3 volts used in SDR
SDRAM, and requires 184-pin DIMM modules rather than 168-pin DIMM
modules used by SDR SDRAM. DDR SDRAM is also known as SDRAM-II,
DDR DRAM and DSDRAM (Double-Speed DRAM).

T wo types of DDR are available at the time of writing: PC1600 & PC2100.
PC1600 DDR SDRAM running at 100MHz will produce about 1.6GB/s memory
bandwidth. PC2100 running at 133MHz will produce 2.1GB/s memory
bandwidth. High memory bandwidth makes DDR an ideal solution for high
performance PC, workstations and servers.

Spread Spectrum

When the motherboard clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference). The Spread
Spectrum function reduces the EMI generated by modulating the pulses so
that the spikes of the pulses are reduced to flatter curves. If you do not
have any EMI problem, leave the setting at Disabled for optimal system
stability and performance. But if you are plagued by EMI, setting to En-
abled for EMI reduction. Remember to disable Spread Spectrum if you are

High Performance/BIOS Setup Defaults

The two options on the main menu allow users to restore all of the BIOS
settings to High Performance defaults or BIOS Setup defaults. The High
Performance Defaults are the default values set by the mainboard manufac­turer for the best system performance but probably will cause a stability
issue. The BIOS Setup Defaults are the default values also set by the
mainboard manufacturer for stable performance of the mainboard.

When you select High Performance Defaults, a message as below appears:

Pressing ‘Y’ loads the default BIOS values that enable the best system
performance but may lead to a stability issue.

The option is for power or overclocking users only. Use of
high performance defaults will tighten most timings to increase
the system performance. Therefore, a high-end system configu­ration is a must, which means you need high-quality VGA
adapter, RAM and so on. We don’t recommend that users

should apply the high performance defaults in their regular
systems. Otherwise, the system may become unstable or even

MSI Smart Key

If security is important to you, the MSI Smart Key is the best solution to

prevent your data in the computer from being accessed by unauthorized people.

In the public workspace, the passwords (BIOS password, system
password, etc.) are not enough to keep your privacy. Do you believe that a
hacker can easily enter your computer and monitor your confidential data? It
happens everyday, everywhere; you just do not know... A password only
stops them at the first gate. If this protection is broken, what else can you rely
on?

The MSI Smart Key is a hardware device that provides you the com­plete and perfect protection on your system. Once the key is installed and
setup, any unauthorized user absolutely can not access and use your computer
without the key. The computer needs the key to boot up, and the operating
system needs the key to work normally. Furthermore, if you have to leave
your desktop for a while, you can simply unplug the key to keep your system
in a safest status.
