Overclock Options [Overclock 5%] Allows you to overclock the CPU speed through the available preset values. Configuration options: [Overclock 5%] [FSB888/DDR2-667] [Overclock 10%] [FSB960/DDR2-800] [Overclock 15%] [FSB1200/DDR2-800] [Overclock 20%] [FSB1280/DDR2-800] [Overclock 30%] [FSB1333/DDR2-667] [FSB1333/DDR2-834] The following item appears only when the AI Overclocking item is set to [AI NOS]. N. O. S. Mode [Auto] Sets the Non-Delay Overclocking System mode. Select either of the following configuration options: Auto - loads the optimum sensitivity and overclocking percentage setting. Configuration options: [Auto] [Disabled] [Enabled] Microcode Updation [Enabled] Allows you to enable or disable the microcode updation. Configuration options: [Disabled] [Enabled] Max CPUID Value Limit [Disabled] Setting this item to [Enabled] allows legacy operating systems to boot even without support for CPUs with extended CPUID functions. Configuration options: [Disabled] [Enabled] -2 Chapter : BIOS setup Execute Disable Function [Disabled] Allows you to enable or disable the No-Execution Page Protection Technology. Setting this item to [Enabled] forces the XD feature flag to always return to zero (0). Configuration options: [Disabled] [Enabled] CPU Internal Thermal Control [Auto] Allows you to disable or set to auto the CPU Internal Thermal Control function. When set to [Auto], the BIOS automatically checks the CPU's capability to enable TM or TM2 support. In TM mode, the CPU power consumption is reduced. In TM2 mode, the CPU core and VID are reduced. Configuration options: [Auto] [Disabled] The following item appears only when you installed an Intel® Pentium® 4 CPU that supports the Enhanced Intel SpeedStep® Technology (EIST). Intel(R) SpeedStep Technology [Disabled] Allows you to use the Enhanced Intel SpeedStep® Technology. When set to [Automatic], you can adjust the system power settings in the operating system to use the EIST feature. Set this item to [Disabled] if you do not want to use the EIST.
