CPU Setup CPU Setup

Intel(R) Speed Shift Technology

Intel(R) Speed Shift Technology is an energy efficient method of frequency control by the hardware rather than relying on OS control.

Options:

  1. Enabled – Default.
  2. Disabled – Intel(R) Speed Shift Technology is turned off.
WMI Setting name Values SVP / SMP Req'd AMD/Intel
SpeedShiftTechnology Disabled, Enabled yes Intel
Intel(R) Hyper-Threading Technology

Intel(R) Hyper-Threading Technology allows multiple logical processors, within the same processor core, to share execution resources and cache hierarchy between logical processors.

Options:

  1. Enabled – Default.
  2. Disabled.

If TxT is set to Enabled, then this item will always be Enabled.

WMI Setting name Values SVP / SMP Req'd AMD/Intel
HyperThreadingTechnology Disabled, Enabled yes Intel
Core Multi-Processing

How many cores are available to the OS.

Options:

  1. Enabled – All CPU cores. Default.
  2. Disabled – Only one core.

If TxT is set to Enabled, then this item will always be Enabled.

WMI Setting name Values SVP / SMP Req'd AMD/Intel
CoreMultiProcessing Enabled, Disabled yes Intel
Efficient-Cores

Options:

  1. Enabled – All CPU cores. Default.
  2. Disabled – Only one core.
WMI Setting name Values SVP / SMP Req'd AMD/Intel
EfficientCores Enabled, Disabled yes Intel
Intel(R) Virtualization Technology

Intel(R) Virtualization Technology allows PC platforms to run multiple applications and operating systems simultaneously in independent partitions, to help to manage and protect the multi-functional capabilities of PCs.

Options:

  1. Enabled – Default.
  2. Disabled.

When Intel(R) Virtualization Technology is turned off and the following are set to Disabled and cannot be changed:
a. VT-d Feature
b. TxT

Additional information is available here: How to enable Virtualization Technology on Lenovo PC computers.

WMI Setting name Values SVP / SMP Req'd AMD/Intel
VirtualizationTechnology Disabled, Enabled yes Intel
VT-d Feature
VT-d support on Intel platforms provides the capability to ensure improved isolation of I/O resources for greater reliability, security, and availability.

Options:

  1. Enabled – Default.
  2. Disabled.

Additional information is available here: VT-d Feature .

WMI Setting name Values SVP / SMP Req'd AMD/Intel
VTdFeature Disabled, Enabled yes Intel
TxT
Trusted Execution Technology (TxT) provides hardware-based mechanisms that help protect against software-based attacks and protects the confidentiality and integrity of all data stored or created on the client PC.

Options:

  1. Enabled
  2. Disabled - Default.

If TxT is set to Enabled, then the Security Chip setting will be set to Enabled automatically.

Additional information is available here: Intel(R) TXT Overview.

WMI Setting name Values SVP / SMP Req'd AMD/Intel
TXTFeature Disabled, Enabled yes Intel
IOMMU
Intel Input/Output Memory Management Unit (IOMMU) is a hardware component that performs address translation from I/O device virtual addresses to physical addresses. This hardware-assisted I/O address translation improves the system performance within a virtual environment.

Options:

  1. Enabled.
  2. Disabled – Default.
WMI Setting name Values SVP / SMP Req'd AMD/Intel
IOMMU Disabled, Enabled yes Intel
C1E Support

C1 is a state where the processor is not executing instructions, but can return to an executing state immediately.

Enhanced C1 state (C1E) provides lower power consumption when the computer is idle.

Options:

  1. Enabled – Default.
  2. Disabled.
WMI Setting name Values SVP / SMP Req'd AMD/Intel
C1ESupport Disabled, Enabled yes Intel
C State Support

Supported CPU power management status to minimize the idle power consumption of processor.

Options:

  1. C1 – C1 only.
  2. C1C3 – C1 and C3.
  3. C1C3C6 – C1, C3 and C6.
  4. C1C3C6C7C8 – C1, C3, C6, C7 and C8.
  5. C1C3C6C7C8C10 – C1, C3, C6, C7, C8 and C10. Default.
WMI Setting name Values SVP / SMP Req'd AMD/Intel
CStateSupport C1, C1C3, C1C3C6, C1C3C6C7, C1C3C6C7C8, C1C3C6C7C8C10 yes Intel
Turbo Mode
Turbo Mode allows the processor to assess its own thermals, current and power to come up with a dynamic upper limit on its frequency benefit.

Options:

  1. Enabled – Default.
  2. Disabled.
WMI Setting name Values SVP / SMP Req'd AMD/Intel
TurboMode Disabled, Enabled yes Intel
