Collaborative Power Control
NOTE: This option is available on G7 and Gen8 servers with Intel processors and on Gen8
servers with AMD processors.
For operating systems that support the Processor Clocking Control Interface (PCCI), enabling this
option allows the operating system to request processor frequency changes even when the server
has the Power Regulator option configured for Dynamic Power Savings Mode. For operating
systems that do not support the PCC Interface or when the Power Regulator is not configured for
Dynamic Power Savings Mode, this option has no impact on system operation.
Options include:
•
Enabled (default)
