CPU Configuration CMOS Setup Utility - Copyright (C) 1985-2008, American Megatrends, Inc. CPU Configuration CPU Configuration Help Item Module Version : 3F.0F Sets the ratio Manufacturer : Intel between CPU Core Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz Clock and the FSB Frequency :2.20GHz Frequency. FSB Speed :800MHz Note: Cache L1 :64 KB Only available when Cache L2 :2048 KB SpeedStep technology Ratio Status :Unlocked (Min:06, Max:11) is disabled. Ratio Actual Value:11 Ratio CMOS Setting C1E Support Limit CPUID MaxVal Execute Disable Bit EIST Function [11] [Enabled] [Disabled] [Enabled] [Disabled] 3 CAUTION Move Enter:Select +/-/:Value F10:Save ESC:Exit F1:General Help F9:Optimized Defaults ► Ratio CMOS Setting This item is used to set the ratio between CPU Core Clock and the FSB Frequency. ► C1E Support C1E 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. ► 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. ► 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. ► EIST Function 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. 28
