CPU Ratio Select Switch: SW1 (Optional)
This switch is used for CPU overclocking by specifying the ratio of the CPU’s internal
clock. You can adjust this value using this switch or you can configure the value
through the BIOS setup. Note that the CPU ratio select switch (SW1) takes
precedence. If you are not familiar with overclocking, it is strongly recommended that
you set the SW1 switch to the CPU default setting.
The layout is KX400+ PRO
