CPU Configuration CMOS Setup Utility - Copyright (C) 1985-2009, American Megatrends, Inc. CPU Configuration Configure advanced CPU settings Module Version:01.08 Help Item Manufacturer : Intel Intel(R) Core(TM) i3 CPU 530 @2.936GHz CPU Host Clock: 2.936GHz Ratio Status:Unlocked (Min:09, Max:22) CPU Host Ratio:22 Ratio CMOS Settings Enhanced C1 Limit CPUID Max Val Virtualization Technology Execute Disable Bit Hyper Threading Active Processor Cores A20M EIST Intel(R) C-STATE Technology [22] [Enabled] [Disabled] [Enabled] [Enabled] [Eabled] [All] [Disabled] [Enabled] [Disabled] Sets the ratio between CPU Core Clock and the FSB Frequency. Move Enter:Select +/-/:Value F10:Save ESC:Exit F1:General Help F7:Previous Values F8:Fail-Safe Defaults F9:Optimized Defaults 3 ► Ratio CMOS Settings This item is used to set the ratio between CPU Core Clock and the FSB Frequency. You can use [+] or [-] to adjust the value. ► Enhanced C1 C1 represents Enhanced HALT State. It is a feature which Intel CPU uses to reduce power consumption when in halt state. C1E drops the CPU's multiplier and voltage to lower levels when a HLT (halt) command is issued. This item is used to enable/disable the C1E support. When disabled, the processor will only retrieve the currently requested cache line. ► Limit CPUID MaxVal This item is used to enable or disable CPUID maximum value limit configuration. Set Limit CPUID MaxVal to 3, it should be [Disabled] for WinXP. ► Virtualization Technology Virtualization (i.e. Intel® Vanderpool Technology) allows a platform to run multiple operating systems and applications in independent partitions or "containers." One physical compute system can function as multiple "virtual" systems. Vanderpool Technology can help improve future virtualization solutions. This item will be displayed only when the CPU is supporting this feature and the setting is used to enable/disable it. ► Execute Disable 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 managers can free IT resources for other initiatives. 25
