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 find 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

=

100MHz

Core/Bus ratio

=

24

then CPU core speed

=

Host Clock x Core/Bus ratio

 

=

100MHz x 24

 

=

2.4 GHz
