◆ MaximumEfficiencyRatio

UINT32 MSR_SANDY_BRIDGE_PLATFORM_INFO_REGISTER::MaximumEfficiencyRatio

[Bits 47:40] Package. Maximum Efficiency Ratio (R/O) The is the minimum ratio (maximum efficiency) that the processor can operates, in units of 100MHz.

Definition at line 141 of file SandyBridgeMsr.h.

◆ MaximumNonTurboRatio

UINT32 MSR_SANDY_BRIDGE_PLATFORM_INFO_REGISTER::MaximumNonTurboRatio

[Bits 15:8] Package. Maximum Non-Turbo Ratio (R/O) The is the ratio of the frequency that invariant TSC runs at. Frequency = ratio * 100 MHz.

Definition at line 118 of file SandyBridgeMsr.h.

◆ RatioLimit

UINT32 MSR_SANDY_BRIDGE_PLATFORM_INFO_REGISTER::RatioLimit

[Bit 28] Package. Programmable Ratio Limit for Turbo Mode (R/O) When set to 1, indicates that Programmable Ratio Limits for Turbo mode is enabled, and when set to 0, indicates Programmable Ratio Limits for Turbo mode is disabled.
