>>>>> Standard Clock Control
Base Clock(BCLK) Control
Enables or disables the control of CPU base clock. Enabled will allow the BCLK Frequency(Mhz) item
belowtobecongurable.Note:Ifyoursystemfailstobootafteroverclocking,pleasewaitfor20seconds
to allow for automated system reboot, or clear the CMOS values to reset the board to default values.
(Default: Disabled)
BCLK Frequency(Mhz)
Allows you to manually set the CPU base clock. The adjustable range is from 100 MHz to 1200 MHz.
ThisitemiscongurableonlyiftheBase Clock(BCLK) Control option is enabled.
Important:ItishighlyrecommendedthattheCPUfrequencybesetinaccordancewiththeCPUspeci-
cations.
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rst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.
