separate logical processors within the operating system. This option is used to enable or

disable the feature. It will be displayed only if your CPU is supporting this feature.
► Active Processor Cores

This item is used to select the number of cores to enable in each processor package.

► CPU Internal PLL Overvoltage

This item is used to enable or disable CPU internal PLL overvoltage for overclocking.

► VID Override for Max Turbo Ratio

This item is used to set VID override for max Turbo Ratio in 1/256 volts.

► IA Core Current Max(1/8 Amp)

This item is used to set IA Core current max value for factory long duration power limit. Default

value is get from CPU MSR.

► Enhanced Intel SpeedStep Technolog

You can enable/disable the EIST (Processor Power Management, PPM) through this item.

Enhanced Intel SpeedStep® technology (EIST) allows the system to dynamically
adjust processor voltage and core frequency, which can result in decreased average
power consumption and decreased average heat production. There are some system
requirements must be met, including CPU, chipset, motherboard, BIOS and operation
system. Please refer to Intel website for more information.

► Turbo Mode

You can enable/disable the Turbo mode.

► Power Limit 1 Value(1/8 Watt)

When the “Turbo Mode” is enabled, this item is used to set the power limit 1 value. you can

change the number by pressing “+/-” keys or input the number you want directly.

► Power Limit 2 Value (1/8 Watt)

When the “Turbo Mode” is enabled, this item is used to set the power limit 2 value. Default

value is get from CPU MSR. you can change the number by pressing “+/-” keys or input the

number you want directly.

► 1-Core/2-Core/3-Core/4-Core/5-Core/6-Core Ratio Limit

When the “Turbo Mode” is enabled, this limit is for 1/2/3/4/5/6 core active. 0 means using the
factory-configured value.

► Limit CPUID Maximum

This item is used to enable or disable CPUID maximum value limit configuration. It should be
[Disabled] for WinXP.

► Execute Disabled Bit

This item is used to enable/disable the Execute Disable Bit feature.

Intel’s Execute Disable Bit functionality can help prevent certain classes of malicious buffer
overflow attacks when combined with a supporting operating system.
Execute Disable Bit allows the processor to classify areas in memory by where application

code can execute and where it cannot. When a malicious worm attempts to insert code in the

buffer, the processor disables code execution, preventing damage and worm propagation.

Replacing older computers with Execute Disable Bit-enabled systems can halt worm attacks,

reducing the need for virus-related repairs. By combining Execute Disable Bit with anti-virus,
firewall, spyware removal, e-mail filtering software, and other network security measures, IT
