Setting Minimum Processor Idle Power Package State
NOTE: This option is available on servers with Intel processors.
Configure the lowest processor idle power state (C-state). The processor automatically transitions
into package C-states based on the Core C-states in which cores on the processor have transitioned.
The higher the package C-state, the lower the power usage of that idle package state. Package
C6 (non-retention) is the lowest power idle package state supported by the processor. Configure
this option only when HP Power Profile is set to Custom.
To set minimum processor idle power package state:
1. From the System Utilities screen, select System Configuration→BIOS/Platform Configuration
(RBSU)→Power Management→Advanced Power Options→Minimum Processor Idle Power
Package State and press Enter.
2. Select one of the following options:
• Package C6 (retention) State
• Package C6 (non-retention) State
• No Package State
3. Press F10 to save your selection.
