SPEC CPU2006 Platform Settings for Intel-based systems
- Hyper-Threading:
- This BIOS option allows the enabling/disabling of Intel's Hyper-Threading (HT) Technology.
HT Technology allows multithreaded software applications execute two threads in parallel within each processor core.
- Turbo Mode:
- Intel Turbo Boost Technology allows processor cores to run faster than the rated operating frequency if they're operating below power, current, and temperature specification limits.
Disabling this feature will reduce power usage but will reduce the system's maximum achievable performance under some workloads.
- C States Support:
- Select supported CPU power management status to minimize the idle power consumption of processor. "C1" is C1 only, "C1C3" is C1 and C3, "C1C3C6" is C1,C3 and C6, "C1C3C6C7" is C1,C3,C6 and C7.
- ICE Performance Modes:
- System thermal management solution. "Better Acoustic Performance" is the system will run with less noise at a normal thermal level. "Better Thermal Performance" is the system will run at a better thermal level with normal acoustic performance. "Full Speed" is all fans in the system will run at full speed.
- C1E Support:
- C1 is a state where the processor is not executing instructions, but can return to an executing state immediately. Select Enhanced C1 state (C1E) for lower power consumption when the computer is idle.
Select whether to enable or disable Enhanced C1 State.
- CPU C3 Report:
- Enable/Disable CPU C3(ACPI C2) report to OS. This in normally Disalbed but can be Enabled for improved performance on certain benchmarks and in certain situations.
- CPU C6 report:
- Enable/Disable CPU C6(ACPI C3) report to OS. This in normally Enabled but can be Disabled for improved performance on certain benchmarks and in certain situations.
