CPU Installation Procedures for Socket 754
1.Please turn off the power and
unplug the power cord before
installing the CPU.
Quick User’s Guide
Open Lever
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 on the
CPU. The gold arrow should
point as shown in the picture.
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
cannot 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.

Installing AMD Athlon64 CPU Cooler Set
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
have the heat sink and cooling fan, contact your dealer to purchase and install
them before turning on the computer.
MSI Reminds You...
Mainboard photos shown in this section are for demonstration of the
cooler installation for Socket 754 CPUs only. The appearance of
your mainboard may vary depending on the model you purchase.
1.Detach the shield off the
backplate’s paster.
2.Turn over the mainboard, and install
the backplate to the proper position.
3.Turn over the mainboard again, and
place the mainboard on the flat
surface. Locate the two screw
holes of the mainboard.

Memory
The mainboard provides 2 slots for 184-pin DDR DIMM (Double In-Line Memory
Module) modules and supports the memory size up to 2GB. You can install DDR 333/
400 modules on the DDR DIMM slots (DIMM 1~2).
Memory Population Rules
Install at least one DIMM module on the slots. Each DIMM slot supports up to a
maximum size of 1GB. Users can install either single- or double-sided modules to
meet their own needs.

1. Make sure that you install memory modules of the same type and
density on DDR DIMMs.
2. For systems using double-sided DDR400 modules in single-channel mode, the maximum DRAM speed is DDR333.
Installing DDR Modules
1. The DDR DIMM has only one notch on the center of module. The module 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.

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 24-Pin Power Connector: JWR1
This connector allows you to connect an ATX 24-pin power
supply. To connect the ATX 24-pin 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 connector.
You may use the 20-pin ATX power supply as you like. If
you’d like to use the 20-pin ATX power supply, please plug your
power supply along with pin 1 & pin 13 (refer to the image at the
right hand). There is also a foolproof design on pin 11, 12, 23 &
24 to avoid wrong installation.
This 12V power connector is used to provide power to the CPU.

Important Notification about Power Issue
nVIDIA chipset is very sensitive to ESD (Electrostatic Discharge), therefore
this issue mostly happens while users intensively swap memory modules under S5
(power-off) states, and the power code is plugged while installing modules. Due to
several pins are very sensitive to ESD, so this kind of memory-replacement actions
might cause chipset system unable to boot. Please follow the following solution to
avoid this situation.
Unplug the AC power cable (shown in figure 1) or unplug the JWR1 & JPW1
power connectors (shown in figure 2 & figure 3) before the 1st installation or during
system upgrade procedure.

ATA133 Hard Disk Connectors: IDE1 & IDE2
The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 66/100/
133 controller that provides PIO mode 0~4, Bus Master, and Ultra DMA 66/
100/133 function. You can connect up to four hard disk drives, CD-ROM
and other IDE devices.
The Ultra ATA133 interface boosts data transfer rates between the
computer and the hard drive up to 133 megabytes (MB) per second. The
new interface is one-third faster than earlier record-breaking Ultra ATA/
100 technology and is backwards compatible with the existing Ultra ATA
interface.
IDE1 (Primary IDE Connector)
The first hard drive should always be connected to IDE1. IDE1 can connect a Master
and a Slave drive. You must configure second hard drive to Slave mode by setting the
jumper accordingly.
IDE2 (Secondary IDE Connector)
IDE2 can also connect a Master and a Slave drive.
