► Memory Multiplier
This item is used to adjust the memory Clock Ratio. The available settimgs are: [Auto], [10.67],
[13.33], [16], [18.67], [21.33].
► 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 (tRP)
This item allows you to select the row precharge time (in clock cycles).
► RAS# to CAS# Delay (tRCD)
This item allows you to select a delay time (in clock cycles) between the CAS# and RAS#
strobe signals.
► RAS# Active Time (tRAS)
This item allows you to set the minimum RAS# active time (in clock cycles).
