3 CPU Configuration CMOS Setup Utility - Copyright (C) 1985-2008, American Megatrends, Inc. CPU Configuration CPU Configuration Help Item Module Version : 3F.0F This should be enabled Manufacturer : Intel in order to enables or Intel(R) Core(TM)2 Quad CPU Q9300 @ 2.50GHz disable the "Enhanced Frequency :2.50GHz Halt State". FSB Speed :1333MHz Cache L1 :128 KB Cache L2 :6144 KB Ratio Actual Value:7.5 C1E Support Limit CPUID MaxVal Virtualization Technology Execute Disable Bit EIST Function [Enabled] [Disabled] [Enabled] [Enabled] [Disabled] Move Enter:Select +/-/:Value F10:Save ESC:Exit F1:General Help F9:Optimized Defaults ► 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. ► 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. ► EIST Function You can enable/disable the EIST (Processor Power Management, PPM) through this item. 31
