Changing the AMD C-State Efficiency Mode

Configure the system to adjust the core frequency in small increments when changing C-States. Enabling this option will monitor the workload and modulate the frequency of the core to maintain a high C0 residency. This has power and latency benefits when the core is not 100% utilized.

Procedure
  1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Power and Performance Options > C-State Efficiency Mode.
  2. Select one of the following:

    • Enable

    • Disable

  3. Save your setting.
