► CAS Latency (tCL)
The number of memory clocks it takes a DRAM to return data after the read CAS_L is assert
ed depends on the memory clock frequency. The value that BIOS programs into the memory
controller is a function of the target clock frequency. The target clock frequency is determined
from the supported CAS latencies at given clock frequencies of each DIMM.
► Row Precharge Time (tRPmin)
This item allows you to select the row precharge time (in clock cycles).
► CAS to RAS(tRCDmin)
This item allows you to select a delay time (in clock cycles) between the CAS# and RAS#
strobe signals.
► Active to Precharge(tRASmin)
This item allows you to set the minimum RAS# active time (in clock cycles).
► Write Recovery(tWRmin)
This item allows you to select the write recovery time (in clock cycles).
► Refresh Recovery(tRFCmin)
Refresh to Refresh or Refresh to Active command interval.
► Internal Write to Read Command(tWTR)
This item allows you to select a delay time
(in clock cycles)
between sending the last data from
a write operation to the memory and issuing a read command.
► Row Active to Row Active(tRRDmin)
This item allows you to select a delay time (in clock cycles) between the RAS# and RAS#
strobe signals.
