BIOS Parameters by Server Model

Advanced BIOS Parameters for C220 and C240 Servers

Name	Description
Intel Turbo Boost Technology	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.
	Note	must be set to Custom or the server ignores the setting
		for this parameter.
Processor Power State C6	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.
	Note	must be set to Custom or the server ignores the setting
		for this parameter.
Processor Power State C1 Enhanced	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.

Frequency Floor Override	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.
