Important:
We do not recommend that you adjust the C U to a higher
frequency ratio because it may result to the C Us or systems
instability and are not guaranteed to provide better system
performance. If you are unable to boot up the system with the
frequency ratio you selected, please power off the system and
set SW1 pins 1-5 to Off (Auto).
