O.C FSB1600 CPU
Enable use of a CPU with 1600 MHz FSB through overclocking. You must install the FSB 1600
MHz CPU with DDR2 800 (or above) memory module(s).
Auto
Disabled
Enabled
CPU Host Clock Control
Enables or disables the control of CPU host clock. Enabled will allow the CPU Host Frequency
item below to be configurable. 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)
CPU Host Frequency (Mhz)
Allows you to manually set the CPU host frequency. This item is configurable only if the CPU
Host Clock Control option is enabled. The adjustable range is from 100 MHz to 700 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.
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
Cruise
Sports
Racing
Turbo
Full Thrust
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.
Performance Enhance
Allows the system to operate at three different performance levels.
