For an 800 MHz FSB CPU, set this item to 200 MHz.
For a 1066 MHz FSB CPU, set this item to 266 MHz.
For a 1333 MHz FSB CPU, set this item to 333 MHz.
For a 1600 MHz FSB CPU, set this item to 400 MHz.
Important It is highly recommended that the CPU frequency be set in accordance with the CPU

C.I.A.2
CPU Intelligent Accelerator 2 (C.I.A.2) is designed to automatically adjust CPU computing power
to maximize system performance. C.I.A.2 allows your system bus to be changed dynamically
based on CPU loading through the use of 5 preset states.
Note: System stability varies, depending on your system hardware components.

Warning: Before using C.I.A.2, please first verify the overclocking capability of your CPU.
As stability is highly dependent on system components, when system instability occurs after
overclocking, lower the overclocking ratio.
