CPU Speed
Check your processor and set this function accordingly. If you set
this to Manual, you can set the CPU Ratio and CPU Frequency accordingly.
CPU Frequenies are: 66, 68, 75, 83 and 100, 103, 112, 117, 124, 129, 133, 138,
143, 148, 153. Though 68, 75, 83, 103, 112, 117, 124, 129, 133, 138, 143,

148 and 153 frequencies are available, it is advised that you use these only
for testing since this is not stable as the CPU is not designed for these
frequencies. CPU ratio are: 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, or 8.
Note: If you set the CPU Ratio and CPU Frequency to be too high, and the
system will not turn on, then restart the system. Press “F10” until bootup.
This will set the default setting.
