Hardware Setup

The mainboard supports Single/Dual Intel® Xeon™ processor(s). The

mainboard uses two CPU sockets called Socket 604 for easy CPU installation.
You can install SINGLE or DUAL CPUs on the board to meet your own
needs. Keep the following points in mind before installing CPU(s):

1. If SINGLE CPU is intended, always install the CPU on the CPU1

socket.

2. To install DUAL CPUs on the board, you must use the same type

of CPUs running at the same FSB frequency.

Central Processing Unit: CPU

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.

MSI Reminds You...

Overheating will seriously damage the CPU and system, always
make sure the cooling fan can work properly to protect the CPU
from overheating.
The system temperature needs to remain under 45°C.
We highly recommend that the direction of inlet air should follow
the direction indicated above for better cooling effect.

CPU1

Recommended inlet air direction

2-4

MS-9125 SSI 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 cut edge. The cut
edge 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.

DIMM Module Combination

The mainboard supports dual channel (144-bit wide) DDR266/200
memory interface. Each channel supports 3 DIMM slots.

Each DIMM slot supports up to a maximum size of 2GB. Users can
install either single- or double-sided modules depending on their needs, but
memory modules must be installed on the board IN PAIRS.

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.

Ultra320 SCSI Connector: SCSI 3 (Channel A)

SCSI (Small Computer System Interface) is a parallel interface standard
for attaching peripheral devices to computers. Ultra320 SCSI is the seventh
generation of SCSI I/O technology, and has a maximum data rate speed of
320 MB/sec. SCSI’s commitment to backward compatibility and legacy sup­port are the primary reasons for its durability as an I/O interface, making
SCSI the industry standard for disk drive connection in virtually all high­performance servers. For detailed pin assignments, please refer to p. 2-17.

RAID IDE2

PRI IDE

ATA100 Connector: PRI IDE

The mainboard offers one Ultra ATA/100 hard drive connector.

ATA133 RAID Connectors: RAID IDE1, RAID IDE2

The mainboard supports high-end Ultra ATA/133 RAID (0, 1, or 0+1)
hard drive interface specifications as well.

The Ultra ATA/133 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.

The low-cost RAID (Redundant Array of Independent Disks) solution
integrates two IDE RAID connectors that support PIO mode 0-4, Bus Master,
and Ultra DMA 33/66/100/133 modes. The IDE RAID connectors allow you
to connect Ultra ATA/DMA hard disks and use RAID technology (RAID 0
striping or RAID 1 mirroring) for high performance, data security and fault
tolerance.

ATA133 RAID Connectors

- You can connect a Master drive to each IDE RAID connector.

- The two connectors support hard disk drives only.

- For more information on ATA133 RAID, please refer to ATA133 RAID 0

or 1 Quick User’s Guide.

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.

Fan Power Connectors: CPUFAN1/2, SYSFAN1/2/3

The CPUFAN1/2 (processor fan) and SYSFAN1/2/3 (system fan) sup­port system cooling fan with +12V. It supports 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...

Always consult the vendors for proper CPU cooling fan.
