PCI Express Generation 2.0 Support
NOTE: This option is available on servers with AMD processors.
This feature controls PCIe Generation 1 or PCIe Generation 2 support and can be used to reduce
system power usage. In addition, this feature can be used to work around issues with devices that
claim PCIe 2.0 support but do not adhere to the PCIe 2.0 specification.
Options include:
•
Auto (default)
•
Force PCI-E Generation 2
•
Force PCI-E Generation 1
IMPORTANT: PCIe Generation 1 devices may not function properly when the PCI Express speed
is forced to PCIe Generation 2. Before changing this option, see the QuickSpecs and user
documentation for all expansion cards.
