Write Recovery Time (Twr) This function specifies the amount of delay (in clock cycles) that must elapse after the completion of a valid write operation, before an active bank can be precharged.

DRAM Command Rate This setting controls the DRAM command rate. Select [1T Command] allows DRAM singlal controller to run at 1T (T=clock cycles) rate. Select [2T Command] makes DRAM siganl controller run at 2T rate. [1T] is faster than [2T]. Setting options: [1T Command], [2T Command].
