4.4.3 Memory Configuration This menu shows the memory configuration settings. Select an item then press to display a pop-up menu with the configuration options. Memory Configuration DRAM Frequency Memory Timing Selectable Cache Latency Time Active to Precharge Delay DRAM RAS# to CAS# Delay DRAM RAS# Precharge Memory Parity Check [Auto] [By SPD] 3 8 4 4 Disabled Select Menu Item Specific Help Set DRAM Frequency. DRAM Frequency [Auto] This item sets the DRAM operating frequency. Configuration options: [DDR266] [DDR320] [DDR400] [Auto] Memory Timing Selectable [By SPD] The DRAM clock are set according to the DRAM SPD (Serial Presence Detect). Select [By SPD] for automatic DRAM clock detection. Select [Manual] to allow setting the succeeding memory items to optimal timings. Configuration options: [Manual] [By SPD] The items CAS Latency Time, Active to Precharge Delay, DRAM RAS# to CAS# Delay, and DRAM RAS# Precharge are configurable only when the Memory Timing Selectable item is set to [Manual]. CAS Latency Time [2.5] This item sets the latency (in clocks) between the DRAM read command and the time the data actually becomes available. Configuration options: [2] [2.5] [3] Active to Precharge Delay [7] This item controls the number of DRAM clocks used for DRAM parameters. Configuration options: [8] [7] [6] [5] DRAM RAS# to CAS# Delay [3] Controls the latency between the DRAM active command and the read/ write command.
