Setting will be hidden. If you use the ratio value to time the CPU frequency, it will be equal to the core speed of the installed processor. Ratio Actual Value This is a read-only item, which displays the ratio actual value of this motherboard. CPU Thermal Throttling You may select [Enabled] to enable P4 CPU internal thermal control mechanism to keep the CPU from overheated. Hyper Threading Technology To enable this feature, it requires a computer system with an Intel Pentium®4 processor that supports Hyper-Threading technology and an operating system that includes optimization for this technology, such as Microsoft® Windows® XP. Set to [Auto] if using Microsoft® Windows® XP, or Linux kernel version 2.4.18 or higher. This option will be hidden if the installed CPU does not support Hyper-Threading technology. Max CPUID Value Limit For Prescott CPU only, some OSes (ex. NT4.0) cannot handle the function with disable. This should be enabled in order to boot legacy OSes that cannot support CPUs with extended CPUID functions. 3.3.2 Chipset Configuration BIOS SETUP UTILITY Advanced Chipset Configuration DRAM Frequency Flexibility Option DRAM CAS# Latency DRAM Command Rate DRAM Voltage AGP Voltage Primary Graphics Adapter AGP Aperture Size AGP Mode AGP Fast Write Onboard AGP Share Memory PCI Delay Transaction OnBoard LAN OnBoard AC'97 Audio Onboard MC'97 Modem [Auto] [Disabled] [Auto] [2T Command] [Auto] [Auto] [PCI] [64MB] [Auto] [Disabled] [Auto] [Disabled] [Eabled] [Auto] [Auto] Options 133MHz 166MHz 200MHz Auto (DDR266) (DDR333) (DDR400) +F1 F9 F10 ESC Select Screen Select Item Change Option General Help Load Defaults Save and Exit Exit v02.54 (C) Copyright 1985-2003, American Megatrends, Inc.

You may also select other value as operating frequency: [133MHz (DDR 266)], [166MHz (DDR 333)], [200MHz (DDR 400)]. Flexibility Option The default value of this option is [Disabled]. It will allow better tolerance for memory compatibility when it is set to [Enabled]. 24
