Installing the Motherboard

1 Install your CPU. Pull up the lever away from the

socket and lift up to 90-degree angle.

2 Locate the CPU cut edge (the corner with the pin

hold noticeably missing). Align and insert the CPU

correctly.

3 Press the lever down and apply thermal grease on

top of the CPU.

4 Put the CPU Fan down on the retention module and

snap the four retention legs of the cooling fan into

place.

5 Flip the levers over to lock the heat sink in place and

connect the CPU cooling Fan power cable to the

CPUFAN connector. This completes the installa-

tion.

CPU Installation Procedure

The following illustration shows CPU installation components.

To achieve better airflow rates and heat dissipation, we suggest that you use

a high quality fan with 4800 rpm at least. CPU fan and heatsink installa-

tion procedures may vary with the type of CPU fan/heatsink supplied. The

form and size of fan/heatsink may also vary.

This motherboard has a Socket 939 processor socket. When choosing a processor, consider

the performance requirements of the system. Performance is based on the processor design,

the clock speed and system bus frequency of the processor, and the quantity of internal

cache memory and external cache memory.

Warning: Over-clocking components can adversely affect the reliability of

the system and introduce errors into your system. Over-clocking can

permanently damage the motherboard by generating excess heat in

components that are run beyond the rated limits.
