By [Auto] is recommended. [Manual] allows you to set each configuration on your own. Timing Mode [Auto] Allows selection of DRAM configuration. Configuration options: [Auto] [Manual] The following items become user-configurable when you set the Timing Mode item to [Manual]. Memclock index value (Mhz) [166Mhz] Allows you to set the DRAM frequency. Configuration options: [100Mhz] [133Mhz] [166Mhz] [200Mhz] CAS# latency (Tcl) [2.5] Allows you to set the latency between the DRAM command and the time the data actually become available. Configuration options: [2] [2.5] [3] Min RAS# active time (Tras) [7T] Controls the number of DRAM clocks used for DRAM parameters. Configuration options: [5T] ~ [15T] RAS# to CAS# delay (Trcd) [3T] Controls the latency between the DRAM active command and the R/W command. Configuration options: [2T] ~ [7T] Row precharge Time (Trp) [3T] Controls the idle clocks after issuing a precharge command to the DRAM. Configuration options: [2T] ~ [7T] 5-14 Chapter 5: BIOS setup
