5 1000 fps limits during operation
You're experiencing a performance issue with your i5 9400f on an MSI Z370 A Pro motherboard. The clock speed jumps to 4 GHz when you start using CPU-intensive programs like Cinebench, then drops back down when idle. This behavior is unusual and could indicate a problem with the BIOS settings, thermal throttling, or driver conflicts. Check your BIOS for any recent changes or updates, ensure your cooler is functioning properly, and verify that the CPU is not overheating under load. If the issue persists, consider running a stress test or consulting MSI support for further diagnosis.
It means higher clock speeds occur during low stress because it operates with just one core.
Since your cooler meets the requirements, investigate whether your board allows MCE support. Check the article for details on enabling AllcoreTurbo to its maximum setting. It may be feasible, but be aware that stability could be affected by minor adjustments. Consider testing if 4Ghz multicore enhancement is available in your BIOS—review the manual thoroughly. Before activating it, search YouTube for relevant videos to ensure compatibility and stability.
