TRCD

Use this to adjust TRCD values. Configuration options: [Auto], [5CLK] to [12CLK]. The default value is [Auto].

TRP

Use this to adjust TRP values. Configuration options: [Auto], [5CLK] to [12CLK]. The default value is [Auto].

TRAS

Use this to adjust TRAS values. Configuration options: [Auto], [15CLK] to [30CLK]. The default value is [Auto].

TRTP
