AMD EPYC

AMD EPYC processors are powerful CPUs made for servers and data centers, built on AMD's Zen architecture. The below settings are from AMD's 4th generation EPYC series.

Recommended BIOS settings for the highest performance:

1. Enable custom mode to allow users to adjust CPU performance, power consumption, and other settings. This helps in fine-tuning the system for the best balance between performance and energy efficiency.
2. Enable core performance boost to allow CPU to automatically increase its speed to handle more intensive tasks, improving overall performance.
3. Disable global C-state control, to prevent the CPU from entering deeper power-saving states known as C-states, which can maintain responsiveness. Note:Disabling C-states can cause additional power consumption and increase thermal temperatures. Monitor both for the workload.
4. Enable/Disable SMT (Simultaneous Multithreading) on the CPU, based on the workload requirement and performance goals. SMT is equivalent to Hyper Threading on Intel CPUs. Note:For optimized performance, refer to Section 6.0 Platform Tuning (ice Non-Specific) and Section 5.0 Tuning ice Driver Settingsfor the recommended OS and adapter level tunings.
