SPEC CPU 2017 Flag Description for ASRockRack System

Operating System Tuning Parameters


Firmware / BIOS / Microcode Settings

Precision Boost Overdrive:
The Precision Boost Overdrive (PBO) is a way to automatically run the processor core faster than the marked frequency. The processor must be working in the power, temperature, and specification limits of the thermal design power (TDP). This results in increased performance of both single and multithreaded applications. Current setting is Auto
SMT Control
SMT is a technology that allows a single physical CPU core to run multiple threads simultaneously. This improves efficiency and performance in multithreaded workloads by utilizing idle execution units within a core Current setting is Auto
SoC/Uncore OC Mode
Forces CPU SoC/uncore components(e.g. Infinity Fabric, memory, and integrated graphics) to run at their maximum specified frequency at all times. May improve performance at the expense of idle power savings. Current setting is Enabled
