Configuring PCI Peer to Peer Serialization

Use the PCI Peer to Peer Serialization option to configure PCI Peer to Peer Serialization.

Certain configurations such as systems populated with multiple GPUs on a processor socket may see increased performance when this feature is enabled.

Procedure
  1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Power and Performance Options > PCIe Peer to Peer Serialization.
  2. Select a setting.
    • Enabled—When enabled, PCIe transactions are interleaved across PCIe root ports of a processor which can result in increased performance in peer to peer communication.

    • Disabled

  3. Save your setting.
