Page 15 highlights

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 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. 2-3

Overheating
Overheating will seriously damage the CPU and system, al-
ways make sure the cooling fan can work properly to protect
the CPU from overheating.
