XP up to
3000+
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.
CPU Clock Frequency Selection
The hardware configuration for CPU clock frequency of the motherboard
is set to 100MHz by default. Therefore, to make a 133MHz CPU run at 133MHz
when it is installed on the board, you have to adjust the CPU clock frequency
through jumpers. To set the clock frequency for the installed CPU, refer to
Jumpers in later section .
As processor technology pushes to faster speeds and higher
performance, thermal management becomes increasingly crucial when
building computer systems. Maintaining the proper thermal environ-
ment is key to reliable operation. As such, the processor must be main-
tained 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 thermal grease between the CPU and heatsink to improve
heat dissipation. Then, make sure that the CPU and heatsink are se-
