!DRAM Timing Selectable [By SPD]
This item enables users to set the optimal timings for items 2 through 5; system default setting “By SPD” follows the SPD information and ensures the system runs stably with optimal performance.
!CAS Latency Time [Auto]
This item enables users to set the timing delay in clock cycles before SDRAM starts a read command after receiving it.
!DRAM RAS# to CAS# Delay [Auto]
This item enables users to set the timing of the transition from RAS (row address strobe) to CAS (column address strobe) as both rows and column are separately addressed shortly after DRAM is refreshed.
!DRAM RAS# Precharge [Auto]
This item enables users to set the DRAM RAS# precharge timing, system default is setting to “Auto” to reference the data from SPD ROM.
!Precharge delay (tRAS) [Auto]
This item allows user to adjust memory precharge time.
