BIOS Parameters by Server Model

Advanced BIOS Parameters for C460 Servers

Name	Description
Enhanced Intel Speedstep Technology	Whether the processor uses Enhanced Intel SpeedStep
	Technology, which allows the system to dynamically adjust
	processor voltage and core frequency. This technology can result
	in decreased average power consumption and decreased average
	heat production. This can be one of the following:
	• Disabled—The processor never dynamically adjusts its
	voltage or frequency.
	• Enabled—The processor utilizes Enhanced Intel
	SpeedStep Technology and enables all supported processor
	sleep states to further conserve power.
	We recommend that you contact your operating system vendor
	to make sure the operating system supports this feature.
Intel Hyper-Threading Technology	Whether the processor uses Intel Hyper-Threading Technology,
	which allows multithreaded software applications to execute
	threads in parallel within each processor. This can be one of the
	following:
	• Disabled—The processor does not permit hyperthreading.
	• Enabled—The processor allows for the parallel execution
	of multiple threads.
	We recommend that you contact your operating system vendor
	to make sure the operating system supports this feature.
Number of Enabled Cores	Allows you to disable one or more of the physical cores on the
	server. This can be one of the following:
	• All—Enables all physical cores. This also enables Hyper
	Threading on the associated logical processor cores.
	• 1 through n—Specifies the number of physical processor
	cores that can run on the server. Each physical core has
	an associated logical core.
	To disable Hyper Threading and have only one logical
	processor core running on the server, select 1.
	We recommend that you contact your operating system vendor
	to make sure the operating system supports this feature.
