Core Center
Click on the Core Center icon in the main menu and the Core Center program will
be enabled.
CoreCenter is just like your PC doctor that can detect, view and adjust the PC
hardware and system status during real time operation.
In the left side it shows the current system status including the Vcore, 3.3V, +5V and
12V. In the right side it shows the current PC hardware status such as the CPU &
system temperatures and all fans speeds.
When you click the red triangles in the left and right sides, two sub-menus will open
for users to adjust the thresholds of system to send out the warning messages.
1-6
Getting Started
Left-wing: Current system status
In the left sub-menu, you can configure the settings of FSB, Vcore, Memory
Voltage and AGP Voltage by clicking the radio button next to each item and make it
available (the radio button will be lighted as yellow when selected), use the “+”
and “-” buttons to adjust, then click “OK” to apply the changes. Then you can click
“Save” to save the values you just configured.
Also you may click “Auto” to start testing the maximum CPU overclocking value.
The CPU FSB will automatically increase the testing value until the PC reboots. Or
you may click “Default ” to restore the default values.
Right-wing: PC hardware status during real time operation
In the right sub-menu, here you can configure the PC hardware status such as
CPU & system temperatures and fan speeds. You may use the scroll bars to adjust
each item, then click “OK” to apply the changes. The values you set for the
temperatures are the maximum thresholds for the system for warnings, and the
value for fan speeds are the minimum thresholds.

Hardware Setup
This chapter provides you with the information about hardware setup procedures. While doing the installation, be
careful in holding the components and follow the installation procedures. For some components, if you install in
the wrong orientation, the components will not work
properly.
Use a grounded wrist strap before handling computer
components. Static electricity may damage the
components.
ONLY FOR SERVICE PERSONEL
Always unplug the power cord before inserting any add-on card or module.

Hardware Setup
Central Processing Unit: CPU
The mainboard supports Intel® Pentium 4 Series 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)
Important
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.

CPU & Cooler Installation
When you are installing the CPU, make sure the CPU has a cooler attached 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.
1.The CPU socket 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.
2.Remove the cap from lever hinge
side (as the arrow shows).
4.Open the load lever.3.The pins of socket reveal.
2-4
Hardware Setup
5.Lift the load lever up and open the
load plate.
7.Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with pure vertical
motion and reinstall.
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.

key
8.Cover the load plate onto the
package.
Important
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. The availability of the CPU land side cover depends on your CPU
packing.

MS-7236 Mainboard
9.Press down the load lever lightly
onto the load plate, and then secure the lever with the hook under
retention tab.
11.Press the four hooks down to fas-
ten the cooler. Then rotate the locking switch (refer to the correct direction marked on it) to lock the
hooks.

switch
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.
Important
1. Check the information in H/W Monitor in BIOS (Chapter 3) for the
CPU temperature.
2. Whenever CPU is not installed, always protect your CPU socket pin with
the plastic cap covered (shown in step 1) to avoid damaging.
2-6
Hardware Setup
Memory
The mainboard provides 4 slots for 240-pin DDR II 667/533/400 DIMM, which supports
the memory size up to 4GB. Since DDR2 modules are not interchangeable with DDR
I and the DDR II standard is not backward compatible, you should always install DDR
II memory module in the DDR II 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)
DIMM1,2 and DIMM3,4
(from left (Green) to right(Orange))
Channel A (DIMM1 & DIMM2): Green
Channel B (DIMM3 & DIMM4): Orange
Memory Module Population Rules
Install at least one DIMM module on the slots. Each channel supports up to a maximum
size of 2GB and maximum 2 bank memory modules.
Important
1. 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.
2. The mainboard supports up to 2 double- side or 4 single-side memory
modules.
-Please select the identical memory modules to install on the dual
channel, and DO NOT install three memory modules on three DIMMs,
or it may cause some failure.
-Always insert the memory modules into the GREEN slots first, and it is
strongly recommended not to insert the memory modules into the ORANGE slots while the GREEN slots are left empty.
-This mainboard DO NOT support the memory module installed with
more than 18 pieces of IC (integrated circuit).
2-7
MS-7236 Mainboard
Installing DDR II Modules
1.The DDR II 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.

Important
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 24-Pin Power Connector: ATX1
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.
