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.

For the latest information about CPU, please visit http://www.msi.com.tw/

program/products/mainboard/mbd/pro_mbd_cpu_support.php.

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.

Introduction to LGA 775 CPU

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.

Hardware Setup

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 align­ment 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 con­firm that the clip-ends are cor­rectly inserted.

11. Press the four hooks down to fas­ten the cooler. Then rotate the lock­ing switch (refer to the correct di­rection marked on it) to lock the
hooks.

9. Press down the load lever lightly

onto the load plate, and then se­cure 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 damage.

3. Whenever CPU is not installed, always protect your CPU socket pin
with the plastic cap covered (shown in Figure 1) to avoid damage.

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.

E-2-7

Hardware Setup

Memory

The mainboard provides 4 slots for 240-pin DDR2 DIMM, which supports the

memory size up to 4GB.

Since DDR2 modules are not interchangeable with DDR1 and the DDR2 stand­ard is not backward compatible, you should always install DDR2 memory module in
the DDR2 slot (DIMM1~DIMM4). Otherwise, you are not able to boot up your system
and your mainboard might be damaged.

For the updated supporting memory modules, please visit http://www.msi.
com.tw/program/products/mainboard/mbd/pro_mbd_trp_list.php.

Introduction to DDR2 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, com­pared 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.

E-2-8

MS-7053 ATX Mainboard

Installing DDR2 Modules

1. The DDR2 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.

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. Please note that each DIMM can work respectively for

single-channel DDR, while both channels (in different color) populated
with same amount of memory size will work as dual-channel DDR, no matter

how many DIMM modules are populated.

Below are the example of single-channel/dual-channel DDR modes.

MSI Reminds You...

You can barely see the golden finger if the module is properly in­serted in the socket.

The mainboard provides connectors to connect to FDD, IDE HDD, case, LAN,
USB Ports and CPU/System FAN.

Floppy Disk Drive Connector: FDD1

The mainboard provides a standard floppy disk drive connector that supports
360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types.

FDD1

Fan Power Connectors: CPUF AN2/SYSFAN2/NBF AN1

The CPUFAN2 (processor fan), SYSFAN2 (system fan) and NBFAN1
(NorthBridge Chipset fan) support system cooling fan with +12V. It supports four/
three-pin head connector. When connecting the wire to the connectors, always take
note that the red wire is the positive and should be connected to the +12V, the black
wire is Ground and should be connected to GND. If the mainboard has a System
Hardware Monitor chipset on-board, you must use a specially designed fan with
speed sensor to take advantage of the CPU fan control.

MSI Reminds You...

1. Always consult the vendors for proper CPU cooling fan.

2. CPUFAN2 supports fan control. CPU fan with 3 or 4 pins are both
available.

3. Please refer to the recommended CPU fans at Intel® official
website.

Hardware Setup

Hard Disk Connectors: IDE1, IDE2 & IDE3 (IDE 2 & IDE3 are optional)

The mainboard has one 32-bit Ultra DMA 66/100 IDE controller integrated in
ICH6/ICH6R, which supports PIO & Bus Master operation modes and it can connect
up to two Ultra ATA drives.

There is also another Ultra DMA 66/100/133 IDE controller integrated in the
optional VIA 6410 IDE Raid Controller, which supports RAID 0 & RAID 1, and can
connect up to four Ultra ATA 133 drives.

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, IDE3 (Third and Secondary IDE Connector)
IDE2 & IDE3 can also connect a Slave and a Master drive.

MSI Reminds You...

If you install two hard disks on cable, you must configure the second
drive to Slave mode by setting its jumper. Refer to the hard disk
documentation supplied by hard disk vendors for jumper setting
instructions.

Serial ATA/Serial ATA RAID Connectors controlled by Intel ICH6/
ICH6R: SA TA1~SA T A4

The SouthBridge of this mainboard is Intel ICH6/ICH6R which supports four
serial ATA connectors SATA1~SATA4.

SATA1~SATA4 are dual high-speed Serial ATA interface ports. Each supports
1st generation serial ATA data rates of 150 MB/s. Both connectors are fully compliant
with Serial ATA 1.0 specifications. Each Serial ATA connector can connect to 1 hard
disk device.

MSI Reminds You...

Please do not fold the serial ATA cable in a 90-degree angle, since
this might cause the loss of data during transmission.
