Host Clock Control option is enabled. The adjustable range is from 100 MHz to 1200 MHz.
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
specifications.
PCI Express Frequency (Mhz)
Allows you to manually set the PCIe clock frequency. The adjustable range is from 90 MHz to
150 MHz.
Auto sets the PCIe clock frequency to standard 100 MHz. (Default: Auto)
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.
Disabled Disables the use of C.I.A.2. (Default)
Cruise Increases CPU frequency by 5% or 7% depending on CPU loading.
Sports Increases CPU frequency by 7% or 9% depending on CPU loading.
Racing Increases CPU frequency by 9% or 11% depending on CPU loading.
Turbo Increases CPU frequency by 15% or 17% depending on CPU loading.
Full Thrust Increases CPU frequency by 17% or 19% depending on CPU loading.
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.
