Table 52. System Profile Settings details (continued) Option Description Memory Frequency Sets the speed of the system memory. You can select Maximum Performance, Maximum Reliability or a specific speed. This option is set to Maximum Performance by default. Turbo Boost Enables or disables the processor to operate in the turbo boost mode. This option is set to Enabled by default. Energy Efficient Turbo Energy Efficient Turbo (EET) is a mode of operation where a processor's core frequency is adjusted within the turbo range based on workload. This option is set to Enabled by default. 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 Patrol Scrub Sets the memory patrol scrub mode. This option is set to Standard 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 Efficient Policy option. Energy Efficient Policy Enables you to select the Energy Efficient Policy option. The CPU uses the setting to manipulate the internal behavior of the processor and determines whether to target higher performance or better power savings. This option is set to Balanced Performance by default. 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 when System Profile is set to Custom. 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. Workload Profile CPU Interconnect Bus Link Power Management PCI ASPM L1 Link Power Management This option allows the user to specify the targeted workload of a server. It allows optimization of performance based on the workload type. This option is set to Not Configured by default. Enables or disables the CPU Interconnect Bus Link Power Management. This option is set to Enabled by default. Enables or disables the PCI ASPM L1 Link Power Management. This option is set to Enabled by default. System Security To view the System Security screen, power on the system, press F2, and click System Setup Main Menu > System BIOS > System Security. Table 53. System Security details Option Description CPU AES-NI Improves the speed of applications by performing encryption and decryption by using the Advanced Encryption Standard Instruction Set (AES-NI). This option is set to Enabled by default. System Password Sets the system password. This option is set to Enabled by default and is read-only if the password jumper is not installed in the system. 50 Pre-operating system management applications
