Windows shows incorrect clock speed

[GPUvsCPU]

Hello everyone, been a while since I posted on here but I am glad to be back.

I currently own a Intel i7 3770k CPU which I overclocked to 4.0Ghz in the BIOS, the problem is when I come to stress testing it the Windows Task Manager shows speeds hitting 4.4Ghz and it shows the maximum speed to be 3.9Ghz.
Now, when I use a program such as CPUZ it shows the max speed under load to 4.0Ghz. Anyone got any ideas?

Many thanks in advance

Ignore what windows says. As long CPU-Z shows the correct clock speed , it is fine.

Okay, that's what I have been doing, any reason why Windows would show this incorrect info?

above is seconded. Try running open hardware monitor or similar during a stress test and check the max CPU speed afterwards, if you want to double check.

Shows 4.0Ghz, any idea of why Task Manager would show different?
