Gigabyte GA-EP45-UD3LR user manual CPU Host Frequency Mhz, PCI Express Frequency Mhz, C.I.A.2

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 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.
