Dynamic Idle Cycle Counter

Common Options : Enabled, Disabled

Quick Review

The Dynamic Idle Cycle Counter BIOS feature controls the memory controller's dynamic page conflict prediction mechanism. This mechanism dynamically adjusts the idle cycle limit to achieve a better page hit-miss ratio, improving memory performance.

When enabled, the memory controller will begin with the idle cycle limit set by DRAM Idle Timer and use its dynamic page conflict prediction mechanism to adjust the limit upwards or downwards according to the number of page misses and page conflicts.

It will increase the idle cycle limit when there is a page miss, to increase the probability of a future page hit.

It will decrease the idle cycle limit when there is a page conflict, to reduce the probability of a future page conflict.

When disabled, the memory controller will just use the idle cycle limit set by DRAM Idle Timer. It will not use its dynamic page conflict prediction mechanism to adjust the limit.

Unlike DRAM Idle Timer, the dynamic page conflict mechanism takes the guesswork out of the equation. So, it is recommended that you enable this BIOS feature for better memory performance, irrespective of whether you are configuring a desktop or server.

However, there might be some server users who prefer to force the memory controller to close all open pages whenever there is an idle cycle, to ensure sufficient refreshing of the memory cells. Although it might seem unnecessary, even extreme, for some; server administrators might prefer to err on the side of caution. If so, you should disable this BIOS feature and set DRAM Idle Timer to 0T.
