Maximum Pci Express Speed - HP ProLiant DL360e User Manual

Maximum PCI Express Speed

NOTE: This option is available on Gen8 servers with Intel processors.
This option enables lowering the maximum PCIe speed that the server allows PCIe devices to
operate at and may be useful in addressing issues with problematic PCIe devices. If a PCIe device
does not run properly at the speed that it was designed for, lowering the speed in which the device
is running may address the problem.
NOTE: This option works in conjunction with the PCIe Gen 3 Control setting. When setting the
PCIe Gen 3 Control to Enabled, this Maximum PCI Express Speed option must be set to Maximum
Supported. For more information about the PCIe Gen 3 Control settings, see
(For Select Devices)" (page
Options include:
Maximum Supported (default)—Configures the platform to run at the maximum speed supported
by the platform or the PCIe device (whichever is lower).
PCIe Generation 1.0—Configures the platform to run at the lowest speed possible in the PCIe
links, which is PCIe Generation 1. When setting this option to PCIe Generation 1.0,
performance of high-end cards such as 10GbE NIC Cards and I/O Accelerators may be
affected.
