Configuring DRAM RAPL Limiting Support

Procedure

  1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Power and Performance Options > DRAM RAPL Options > DRAM RAPL Limiting Support.
  2. Select a value:

    • Disabled–- Disables DRAM power limiting so that neither System Firmware nor Operating system software is able to limit the DRAM power.

    • OS Control Mode–- Enables DRAM power limiting so that only the Operating system software is able to programme the DRAM power limit.

    • BIOS Control Mode–- Enables DRAM power limiting so that only the system firmware is able to programme the DRAM power limit during POST.

    TIP
    DRAM RAPL values are applied to an entire processor's memory. This value limits the total power from all the memory attached at the processor socket level.
  3. Save your changes.
