2.3 CPU Frequency Ratio
CPU Frequency Ratio Select - SW1
The table above shows the available frequency ratios and their
corresponding DIP switch setting. The black rectangles on the SW1
illustration denote the part that is protruding, the “adjustable” switch.
Make sure SW1 is set correctly before applying power, otherwise
you will not be able to power-on the system.
Not all AMD CPUs support the multiplier overclocking function.
Please give special attention to “L1” on the CPU. L1’s four bridges
must be closed (short) in order for the frequency ratio selected on
SW1 to take effect. The figure below will help you identify the type
of CPU that would allow you to adjust its frequency ratio.
