High-temperature slowdown in I5 11400F under cold conditions
High-temperature slowdown in I5 11400F under cold conditions
Never encounter consistent 4.4GHz performance beyond controlled lab settings. The peak boost at 4.4GHz is exclusive to single-core testing. When multiple cores are active, the output diminishes. The overall maximum all-core boost reaches around 4.2GHz, matching reported figures like 4.17GHz. Higher speeds are uncommon. To achieve optimal performance, adjust BIOS settings. Limits vary by board but generally appear in a configuration menu labeled "Short Term Power Limit / Long Term Power Limit" or similar. Enter the highest permissible value for both (typically 125–250) and extend PL2 duration if needed.

Hola, me alegra que preguntes. Investigué mi BIOS y vi lo siguiente al iniciar una prueba de estrés con CPU Z o Prime95. Al principio el reloj muestra 4.17GHz, pero poco a poco baja hasta 85w, luego cae a 65w y se queda quieto. Además, las frecuencias también bajan y se estabilizan en 3.4GHz con 65w. ¿Alguna idea? Pd: lo siento por mi inglés, soy hablante nativo de español.
No problem. Writing in French doesn’t give me an advantage—foreign languages are tough. The first image shows the Current Long Duration Package Power Limit at 65 Watts and the Current Package Power Time Window at 224 seconds. This means the CPU will cap at 65W after 224 seconds, which explains why it slows down over time. It seems you’re aiming to push the long duration limit up to its maximum of 4095. If you do that, the CPU shouldn’t slow down due to power limits anymore. An 11400F won’t exceed 150W under any conditions—4095W is essentially “No Power Limit.” Can you save it with that setting?
Usually, the default settings for power limits are 4095. If you're unsure, consider extending the current power window values to a longer duration.
Some B460 boards may have BIOS settings for power limits that aren't functioning properly. The BIOS could allow you to set a power limit of 4095, but upon booting, it might default to your CPU's standard 65W. Try enabling ThrottleStop at https://www.techpowerup.com/download/tec...ottlestop/. Open the TPL window and share a screenshot so I can check your actual settings. If the limits aren't locked, ThrottleStop lets you adjust them to your preference. The ThrottleStop Limit Reasons window will verify if your CPU is applying power limits. Exit HWiNFO when using Limit Reasons to prevent conflicts between the programs.
The image you shared indicated the present limit is configured at 65 Watts. If you didn’t store that 4095 figure, the threshold remains 65W. When you saved it correctly, the limit stays unchanged; otherwise, you might test lower numbers such as 95, 125, or 150 to find a suitable value. Alternatively, you can increase the Package Power Time Window to allow extended operation, and think about applying an undervolt for better power margin at that capacity.
