Maximum PCI Express Speed

When Power Profile is set to Custom, use this option to lower the maximum PCI-express speed at which the
server enables PCI-express devices to operate. Doing so can resolve issues with problematic PCI-express
devices. Maximum Supported enables the platform to run at the maximum speed supported by the platform
or the PCIe device (whichever is lower.)
NOTE:
Changing this setting from Maximum Supported might affect the performance of high-end cards, such as
10GbE NIC cards and I/O accelerators.

Setting the maximum PCI-express speed

Prerequisite
Power Profile is set to Custom.
Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Power Management > Advanced Power Options > Maximum PCI Express Speed and press
Enter.
2. Select a setting and press Enter.
a. Maximum Supported—Configures the platform to run at the maximum speed supported by the
platform or the PCIe device (whichever is lower.)
b. PCIe Generation 1.0—Configures the platform to run at PCIe Generation 1.0, the lowest speed
possible in the PCIe links.
3. Press F10.

Dynamic Power Savings Mode Response

When Power Profile is set to Custom, use this option to enable the system ROM to control processor
performance and power state depending on the processor workload. Fast enables a fast response time, and
is optimal for most workloads where low latency response to an increase in processor demand is a
requirement.
NOTE:
Depending on your processor workload, changing this option from Fast can negatively affect performance.
