K7VAT
System Board 13
2-2-1 CPU Frequency settings
The frequency the CPU runs at internally depends on the FSB (Front Side Bus) Frequency
that is provided to it and the multiplier setting. As example, a 800MHz CPU would run at
100MHz with a multiplier setting of 8x.
Frequency
The K7VAT (K7VAT+)
motherboard allows for setting of the frequency through the
BIOS. To change the CPU frequency, go to the
Voltage / Frequency Control
page in the
BIOS setup, the
CPU Host / PCI Clock
item will allow you select the CPU frequency. This
is explained in more detail in the BIOS section.
Multiplier
The K7VAT (K7VAT+)motherboard allows you use the default CPU multiplier. This can
be selected through JP3. If JP3 is open, the default CPU multiplier (recommended) is used
by the motherboard, if JP3 is closed, the multiplier set by SW1 is used.
JP3: Multiplier Source Select:

JP3 Setting
Closing JP3 allows setting of the multiplier through SW1, refer to the table below:

You need to close JP3 only in case you plan to run the CPU at a frequency
higher than it was specified for (known as overclocking). Note however that we
do not guarantee proper functioning of your system if you overclock your CPU.
In case of overclocking the fan becomes even more important, since the higher
frequency causes the CPU to generate more heat.
