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.
Before installing the Processor
This motherboard automatically determines the CPU clock frequency and system bus
frequency for the processor. You may be able to change these settings by making changes
to jumpers on the motherboard, or changing the settings in the system Setup Utility. We
strongly recommend that you do not over-clock processors or other components to run
faster than their rated speed.
On most motherboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the clips.
Also, install the cooling fan in a well-lit work area so that you can clearly
see the motherboard and processor socket.
