transmitted from the module.
► DRAM RAS# to CAS# Delay (tRCD)
This item allows you to select a delay time (in clock cycles) between the CAS and RAS strobe
signals.
► DRAM RAS# Precharge (tRP)
This item allows you to select the DRAM RAS precharge time (in clock cycles).
► Precharge Delay (tRAS)
This item allows you to set the precharge delay time (in clock cycles).

[533M���] and [667M���].
Note: �hen you use the CPU that FSB is 1333M���, the options are [Auto], [500M���],
