DRAM Timing Configuration
DRAM Frequency
If [Auto] is selected, the motherboard will detect the memory module(s) inserted
and assign the appropriate frequency automatically.
Primary Timing
CAS# Latency (tCL)
°e time between sending a column address to the memory and the beginning of the data
in response.
RAS# to CAS# Delay and Row Precharge (tRCDtRP)
RAS# to CAS# Delay : °e number of clock cycles required between the opening of a row
of memory and accessing columns within it.
Row Precharge: °e number of clock cycles required between the issuing of the precharge
command and opening the next row.
RAS# Active Time (tRAS)
°e number of clock cycles required between a bank active command and issuing the
precharge command.
Command Rate (CR)
°e delay between when a memory chip is selected and when the first active command can
be issued.
Secondary Timing
Write Recovery Time (tWR)
°e amount of delay that must elapse aſter the completion of a valid write operation,
before an active bank can be precharged.
