Hardware Setup
Central Processing Unit: CPU
The mainboard supports Intel®Pentium 4 Prescott processor. The mainboard
uses a CPU socket called LGA775. When you are installing the CPU, make sure to
install the cooler to prevent overheating. If you do not have the CPU cooler,
contact your dealer to purchase and install them before turning on the computer.

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 speci-
fications is not recommended. We do not guarantee the damages
or risks caused by inadequate operation or beyond product
specifications.
Introduction to LGA 775 CPU The surface of LGA 775 CPU.
Remember to apply some sili-
cone heat transfer compound on

2. Remove the cap from lever hinge
side (as the arrow shows).
1. The CPU has a plastic cap on it to
protect the contact from damage.
Before you install the CPU, always
cover it to protect the socket pin.
3. The pins of socket reveal.
CPU & Cooler Installation
When you are installing the CPU, make sure the CPU has a cooler at-
tached on the top to prevent overheating. If you do not have the cooler, contact
your dealer to purchase and install them before turning on the computer. Meanwhile,
do not forget to apply some silicon heat transfer compound on CPU before installing
the heat sink/cooler fan for better heat dispersion.
Follow the steps below to install the CPU & cooler correctly. Wrong installation
will cause the damage of your CPU & mainboard.
4. Open the load lever.

6. After confirming the CPU direction
for correct mating, put down the
CPU in the socket housing frame.
Be sure to grasp on the edge of
the CPU base. Note that the align-
ment keys are matched.
8. Cover the load plate onto the
package.
7. Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with pure vertical
motion and reinstall.

10. Align the holes on the mainboard
with the heatsink. Push down the
cooler until its four clips get
wedged into the holes of the
mainboard.
12.Turn over the mainboard to con-
firm that the clip-ends are cor-
rectly inserted.
11. Press the four hooks down to fas-
ten the cooler. Then rotate the lock-
ing switch (refer to the correct di-
rection marked on it) to lock the
hooks.
9. Press down the load lever lightly
onto the load plate, and then se-
cure the lever with the hook under
retention tab.

MSI Reminds You...
1.Confirm if your CPU cooler is firmly installed before turning on your
system.
2.Do not touch the CPU socket pins to avoid damaging.
3. Whenever CPU is not installed, always protect your CPU socket pin
with the plastic cap covered (shown in Figure 1) to avoid damaging.
4. Please note that the mating/unmating durability of the CPU is 20 cycles.
Therefore we suggest you do not plug/unplug the CPU too often.

Hardware Setup
Memory
The mainboard provides 2 slots for 184-pin DDR1 DIMM (Double In-Line Memory
Module) modules and 2 slots for 240-pin DDR2 DIMM, which supports the memory
size up to 2GB.
Since DDR2 modules are not interchangeable with DDR1 and the DDR2 stand-
ard is not backward compatible, you should always install DDR2 memory module in
DDR2slot(DIMM1&DIMM3),andDDR1memorymoduleinDDR1slot(DIMM2&DIMM4).
Wrong installation may cause damage of mainboard. Meanwhile, you are not able to
boot up your system if you install DDR1 & DDR2 memory modules simultaneously.

DIMM1~DIMM4
(from left to right)
DIMM1 & DIMM3 are for DDR2 memory module

Introduction to DDR2 & DDR1 SDRAM
DDR2 is a new technology of memory module, and its speed is the top limit of
current DDR1 technology. DDR2 uses a 1.8V supply for core and I/O voltage, com-
pared to 2.5V for DDR1, and requires 28% less power than DDR1 chips. DDR2 truly
is the future of memory, but will require some changes as the technology is not
backwardly compatible and only motherboards specifically designed for DDR2 memory
will be able to support these chips.
DDR2 incorporates new features at the chip level that give it better signal
integrity, thereby enabling higher clock speeds.
DDR2 modules have 240 pins, versus 184 pins on a DDR1 module, and the
length of DDR2 module is 5.25”. DDR2 modules have smaller and tighter spaced pins.
The height of DDR2 modules varies, but they will typically be less than 1.3” in height.
DDR1 SDRAM is similar to conventional SDRAM, but doubles the rate by
transferring data twice per cycle. It uses 2.5 volts, and requires 184-pin DIMM modules.

E2-8
MS-7058 ATX Mainboard
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.
Volt Notch
MSI Reminds You...
You can barely see the golden finger if the module is properly in-
serted in the socket.
Memory Module 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. While using dual-channel DDR function, it is available for you
to install memory modules with different sizes (for both DDR1 & DDR2 module), which
will run in “asymmetric mode”. However, it is strongly recommended that you install
same-size memory modules for better performance, which runs in “interleaved mode”.
Please refer to the following table for the available memory populations.
Other combination may cause damage to your mainboard.

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 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

1. These two connectors connect to the ATX power supply and have to
work together to ensure stable operation of the mainboard.
2. Power supply of 350 watts (and above) is highly recommended for
system stability.
3. ATX 12V power connection should be greater than 18A.
