Peripheral Configuration

  • Spread Spectrum Clock: Enable clock Spread Spectrum feature. Recommended to keep disabled
  • PCIe SR-IOV Support: Set IO Virtualization
  • Turn Off unused PCI/PCIe clocks:
    • Disabled - all clocks turned On
    • Enabled - clocks for empty PCI/PCIe slots will be turned off to save power, especially for EMI test.
Platform must be powered off for changes to take effect.

HDD Configuration

Set hard drive and controller configuration:

  • SATA Device: Enable/Disable SATA device.
  • Interface Combination: Select the SATA controllers operating mode. Use this mode for SSD disks.
  • Aggressive Link Power: If enabled, turns on Aggressive Link Power Management on all HDD ports.
  • Serial ATA Port i:
    • SATA Device Type: Select 'Solid State Drive' only if SSD device is connected to port i

System Agent (SA) Configuration

Displays and provides options to change the SA settings

  • Intel(R) VT for Directed I/O (VT-d): Enables/Disables Intel Virtualization Technology for Directed I/O (VT-d) by reporting the I/O device assignment to VMM through DMAR ACPI tables
  • CPU PCIEx8 Port Configuration: PCI Express Port Configuration
    • Always Enable CPU PCIE (x8, x1): Enable CPU PCIE
    • CPU PCIE ASPM: Disabled/L0S/L1/L0S and L1/Auto - CPU PCIEx8 ASPM settings
  • Spread Spectrum clock chip: Enable clock Spread Spectrum feature.
    • Hardware - Spread is controlled by chip
    • Software - Spread is controlled by BIOS
