JP9, JP10: CPU Overclocking
Use JP9 and JP10 2-pin jumpers when overclocking the CPU bus speed
from 66MHz to 100MHz or 100MHz to 133MHz. Refer to the table
below. Note that some processors cannot be overclocked because their
bus speed has been ‘locked’ by the manufacturer and overclocking can
cause the system to hang or become unstable.
