DescriptionName
Whether the processor uses Intel Turbo Boost Technology,
which allows the processor to automatically increase its
frequency if it is running below power, temperature, or voltage
specifications. This can be one of the following:
• Disabled—The processor does not increase its frequency
automatically.
• Enabled—The processor utilizes Turbo Boost Technology
if required.
must be set to Custom or the server ignores the setting
for this parameter.
Note
Intel Turbo Boost Technology
Whether the BIOS sends the C6 report to the operating system.
When the OS receives the report, it can transition the processor
into the lower C6 power state to decrease energy usage while
maintaining optimal processor performance. This can be one of
the following:
• Disabled—The BIOS does not send the C6 report.
• Enabled—The BIOS sends the C6 report, allowing the
OS to transition the processor to the C6 low power state.
must be set to Custom or the server ignores the setting
for this parameter.
Note
Processor Power State C6
Whether the CPU transitions to its minimum frequency when
entering the C1 state. This can be one of the following:
• Disabled—The CPU continues to run at its maximum
frequency in C1 state.
• Enabled—The CPU transitions to its minimum frequency.
This option saves the maximum amount of power in C1
state.
Processor Power State C1 Enhanced
Whether the CPU is allowed to drop below the maximum
non-turbo frequency when idle. This can be one of the following:
• Disabled— The CPU can drop below the maximum
non-turbo frequency when idle. This option decreases
power consumption but may reduce system performance.
• Enabled— The CPU cannot drop below the maximum
non-turbo frequency when idle. This option improves
system performance but may increase power consumption.
