Intel (R) SpeedStep(tm) tech. Intel (R) SpeedStep(tm) tech. is Intel's new power saving technology. Processor can switch between multiple frequency and voltage points to enable power savings. If you select [Auto], you need to set the "Power Schemes" as "Portable/Laptop" to enable this function. 3.3.2 Chipset Configuration BIOS SETUP UTILITY Advanced Chipset Configuration DRAM Frequency Flexibility Option DRAM CAS# Latency DRAM Bank Interleave Precharge to Active (Trp) Active to Precharge (Tras) Active to CMD (Trcd) REF to ACT/REF to REF (Trfc) ACT (0) to ACT (1) (Trrd) Read to Precharge (Trtp) Write to Read CMD (Twtr) Write Recovery Time (Twr) DRAM BUS Selection DRAM Command Rate [Auto] [Disabled] [Auto] [Auto] [Auto] [Auto] [Auto] [Auto] [Auto] [Auto] [Auto] [Auto] [Auto] [2T Command] DRAM Voltage AGP Voltage [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. DRAM Frequency If [Auto] is selected, the motherboard will detect the memory module(s) inserted and assigns appropriate frequency automatically. You may also select other value as operating frequency: [133MHz (DDR 266)], [166MHz (DDR 333)], [200MHz (DDR 400)] for DDR; [266MHz (DDRII 533)], [333MHz (DDRII 667)] for DDRII. Flexibility Option The default value of this option is [Disabled]. It will allow better tolerance for memory compatibility when it is set to [Enabled]. DRAM CAS# Latency Use this item to adjust the means of memory accessing. Configuration options: [Auto], [2.5], [2], and [3] for DDR; [Auto], [3], [4], [5] for DDRII. DRAM Bank Interleave Use this option to select DRAM Bank Interleave. Configuration options: [Auto], [Disabled], [2-Way], [4-Way], and [8-Way]. The default value is set to [Auto] to set the timing by dram SPD. Precharge to Active (Trp) Use this option to select Precharge to Active (Trp). Configuration options: [Auto], [2T], [3T], [4T], and [5T]. The default value is set to [Auto] to set the timing by dram SPD. 33
