Hardware Setup

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.

As processor technology pushes to faster speeds and higher performance, ther-

mal management becomes increasingly crucial when building computer

systems. Maintaining the proper thermal environment is key to reliable

operation. As such, the processor must be maintained in the specified thermal

requirements.

AMD Athlon™/Duron™/Athlon™ XP processor with a speed of 600MHz

and above requires a LARGER heatsink and fan. You also need to add ther-

mal grease between the CPU and heatsink to improve heat dissipation. Then,

make sure that the CPU and heatsink are securely fastened and in good con-

tact with each other. These are needed to prevent damaging the processor and

ensuring reliable operation. If you want to get more information on the proper

cooling, you can visit AMD’s website for reference.

WARNING! Thermal Issue for CPU

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 14

then CPU core speed = Host Clock x Core/Bus ratio

= 100MHz x 14

= 1.4 GHz
