Act Bank A to B CMD Delay

Common Options : 2 Cycles, 3 Cycles

Quick Review

This BIOS feature specifies the minimum amount of time between successive ACTIVATE commands to the same DDR device. The shorter the delay, the faster the next bank can be activated for read or write operations. However, because row activation requires a lot of current, using a short delay may cause excessive current surges.

For desktop PCs, a delay of 2 cycles is recommended as current surges aren't really important. The performance benefit of using the shorter 2 cycles delay is of far greater interest. The shorter delay means every back-to-back bank activation will take one clock cycle less to perform. This improves the DDR device's read and write performance.

Switch to 3 cycles only when there are stability problems with the 2 cycles setting.
