Setting Intel DMI Link Frequency

Use the Intel DMI Link Frequency option to force the link speed between the processor and south bridge to run at slower speeds. Doing so can reduce power consumption, but can also impact system performance.
NOTE:

You can configure this option on systems with two or more CPUs.

Procedure
  1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Power and Performance Options > Intel DMI Link Frequency.
  2. Select a setting.

    • Gen 1 Speed

    • Gen 2 Speed

  3. Save your setting.
