Central Processing Unit: CPU 
The mainboard supports AMD'' Athlon™, Athlon™ XP and Duron™ 
processors in the 462 pin package. The mainboard uses a CPU socket called 
Socket A 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.
