FCC-B Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits for a class
B digital device, pursuant to part 15 of the FCC rules. These limits are designed
to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses
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.

Hardware Setup
Central Processing Unit: CPU
The mainboard supports AMD® Athlon™, Athlon™ XP and Duron™
processors in the 462 pin package. The mainboard uses a CPU socket called
Socket A 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.
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 Athlon™/Duron™/Athlon™ XP processor with a speed of 600MHz
and above requires a 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. If you want to get more information on the proper
cooling, you can visit AMD’s website for reference.
WARNING! Thermal Issue for CPU
CPU Core Speed Derivation Procedure
CPU Clock multiplied by Core/Bus ratio equals the CPU core speed.
For example:
If CPU Clock = 100MHz
Core/Bus ratio = 14
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHz x 14
= 1.4 GHz

MS-6777 M-ATX Mainboard
1. Please turn off the power and
unplug the power cord before
installing the CPU.
2. Pull the lever sideways away
from the socket. Make sure
to raise the lever up to a 90degree angle.
3. Look for the gold arrow. The
gold arrow should point towards the lever pivot. The
CPU can only fit in the correct orientation.
4. If the CPU is correctly
installed, the pins should be
completely embedded into the
socket and can not be seen.
Please note that any violation
of the correct installation procedures may cause permanent
damages to your mainboard.
5. Press the CPU down firmly
into the socket and close the
lever. As the CPU is likely to
move while the lever is being
closed, always close the lever
with your fingers pressing
tightly on top of the CPU to
make sure the CPU is properly and completely embedded into the socket.

MSI Reminds You...
Please apply some heat sink paste on top of your CPU to dissipate the heat more effectively.
The following instructions will guide
you through the heat sink installation
process. Please consult your agent for
the proper CPU cooler set.
1. Position your CPU cooler set onto
the CPU.
2. Use one end of the clip to hook
the latch of the CPU sliding plate.
3. Hook the other latch to fix the
cooling fan set. You may need a
screw drive to press down the
other side of the clip.
4. Connect the fan to the power supply connector provided on your
mainboard.

MS-6777 M-ATX Mainboard
CPU Clock Frequency Selection through Jumpers
The hardware configuration for CPU clock frequency of the motherboard
is set to 100MHz by default. Therefore, to make a 133MHz CPU run at 133MHz
when it is installed on the board, you have to adjust the CPU clock frequency
through jumpers.
To set the clock frequency for the installed CPU, refer to Jumpers in
later section.
MSI Reminds You...
Overheating
Overheating will seriously damage the CPU and system, always make sure the cooling fan can work properly to protect
the CPU from overheating.
Replacing the CPU
While replacing the CPU, always turn off the ATX power supply or unplug the power supply’s power cord 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.

Memory
DDR DIMM Slots
(DIMM 1~2)
Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transferring data twice per cycle. It 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. High memory
bandwidth makes DDR an ideal solution for high performance PC, workstations and servers.
The mainboard provides:
h 2 DDR SDRAM DIMMs to support Dual Channel DDR266/333,
max. 2GB (nForce2 IGP only)
h 2 DDR SDRAM DIMMs to support Single Channel DDR266/333/
400, max. 2GB (nForce2 400 only)
You can install DDR400 (nForce2 400 only)/333/266/200 modules on
the DDR DIMM slots (DIMM 1~2).
2-8
MS-6777 M-ATX Mainboard
DIMM Module Combination
Install at least one DIMM module on the slots. You can install either
single- or double-sided modules in any order to meet your own needs.
Memory modules can be installed in any combination as follows:
Installing DDR Modules
1. The DDR DIMM has only one notch on the center of module. The mod-
ule will only fit in the right orientation.
2. Insert the DIMM memory module vertically into the DIMM slot. Then
push it in until the golden finger on the memory module is deeply inserted in the socket.
3. The plastic clip at each side of the DIMM slot will automatically close.
MSI Reminds You...
You can barely see the golden finger if the module is properly
inserted in the socket.

Power Supply
The mainboard supports ATX power supply for the power system. Before inserting the power supply connector, always make sure that all components are installed properly to ensure that no damage will be caused.
ATX 20-Pin Power Connector: JWR1
ATX 12V Power Connector: JPW1
The JWR1 provides power to the mainboard while the JPW1 is used to
supply power to the CPU. These two connectors connect to the ATX power
supply and have to work together to ensure stable operation of the mainboard.
To connect to the ATX power supply, make sure the plug of the power supply
is inserted in the proper orientation and the pins are aligned. Then push down
the power supply firmly into the connectors.
