Row Precharge Time (tRP) (9)
This item specifies Row precharge to Active or Auto-Refresh of the same bank.
Memory Timing Configuration
This item shows the information of Memory Timing.
This item determines the operation of DDR SDRAM memory CAS (colulmn address
strobe). It is recommended that you leave this item at the default value. The 2T
setting requires faster memory that specifically supports this mode.
Memory Multiplier Configuration
This item shows the information of Memory multiplier Configuration.
This item specifies the RAS# to CAS# delay to Rd/Wr command to the same bank.
Row Refresh Cycle Time (tRFC) (74)
This item specifies the row refresh cycle time.
