User's Manual

DescriptionName
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.
Enhanced Intel Speedstep 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.
Intel Hyper-Threading Technology
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.
