Hardware Setup
Central Processing Unit: CPU
The mainboard supports Intel
®
Pentium
®
4 processors in the 478 pin package.
The mainboard uses a CPU socket called PGA478 for easy CPU installation. 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.
CPU Core Speed Derivation Procedure
If
CPU Clock
=
200MHz
Core/Bus ratio
=
12
then
CPU core speed
=
Host Clock x
Core/Bus ratio
=
200MHz
x
12
=
2.4 GHz
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.
Overclocking
This motherboard is designed to support overclocking. However, please
make sure your components are able to tolerate such abnormal settings
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.
