Windows 10: Why is Windows 11 not using my CPU's full frequency?

The CPU that I use is an Intel Core i5-10400. With a base frequency of ~2.90GHz and a max turbo frequency of ~4.30GHz. My system is set up to ultimate performance. However, as I check task manager, the CPU frequency seems to have reached the limit of ~3.98GHz. Whilst in Windows 10, my CPU can reach up to its max turbo frequency. Can someone explain why this happens? Is this an OS issue? Thank you for your response.

INCORRECT CPU FREQUENCY READING

Hello Muhammad,

CPU usage depends on the applications that are open to your device. To isolate the problem, we suggest that you answer the following questions:

• Can you include a screenshot of the CPU reading?
• Have you tried performing a
  clean boot to eliminate software conflicts?
• What troubleshooting steps have you done so far?

Looking forward to your response.

 

CPU 101 -- Frequency Vs. Boost

I'd say forget about base frequency, you could force computer to run much lower anyway. It's just highest frequency CPU would run at if no boost is allowed.If boost is enabled, under appropriate load some cores will boost to higher frequency until certain step and if even more load is applied one core will boost to even higher frequency.

 

Overclock cpu max frequency constantly changing in task manager

Hi,

I'm overclocking my Intel 8700k to 5Ghz and every time I check the current frequency in task manager the max is constantly changing. I have high-performance power settings on windows enabled and I have also disabled CPU state and Intel SpeedStep in the BIOS.
I also noticed that when using other tools to display my GPU and CPU performance they show my CPU max frequency is exactly 5Ghz, why does Task Manager constantly display a constantly changing frequency?

Any suggestions?

Much appreciated
