Table 17. System Profile Settings details (continued) Option Description C1E Enables or disables the processor to switch to a minimum performance state when it is idle. This option is set to Enabled by default. C States Enables or disables the processor to operate in all available power states. C States allow the processor to enter lower power states when idle. When set to Enabled (OS controlled) or when set to Autonomous (if hardware controlled is supported), the processor can operate in all available Power States to save power, but may increase memory latency and frequency jitter. This option is set to Enabled by default. Memory Refresh Rate Sets the memory refresh rate to either 1x or 2x. This option is set to 1x by default. Uncore Frequency Enables you to select the Uncore Frequency option. Dynamic mode enables the processor to optimize power resources across cores and uncores during runtime. The optimization of the uncore frequency to either save power or optimize performance is influenced by the setting of the Energy Efficiency Policy option. Monitor/Mwait Enables the Monitor/Mwait instructions in the processor. This option is set to Enabled for all system profiles, except Custom by default. NOTE: This option can be disabled only if the C States option in the Custom mode is set to disabled. NOTE: When C States is set to Enabled in the Custom mode, changing the Monitor/ Mwait setting does not impact the system power or performance. PCI ASPM L1 Link Power Management Enables or disables the PCI ASPM L1 Link Power Management. This option is set to Enabled by default.
