It reached a peak of 3.9GHz!
I have a doubt about this claim. It seems contradictory—some sites list 4.4GHz while the actual performance is 3.9GHz. I see discussions online suggesting it works only on single-core processors, not multiple cores. This makes me think it might be misleading or even a scam in my opinion. The link you shared mentions 4.40GHz, but the text says otherwise. It would help to verify such details from reliable sources or manufacturer specifications. Disappointing indeed.
No? That's essentially the highest frequency the processor can boost. Press the (?) button next to "Max turbo frequency." It seems Intel also restricts all-core turbo on non-K CPUs. Clock speed and core count influence how much current a CPU consumes. The motherboard must be able to supply the CPU with enough power to maintain those speeds. If it can't, the CPU will operate at its best with the available power, even if it's below its full capacity. Cheap or low-end motherboards often have weaker power delivery as a cost-saving choice, which typically isn't an issue since they're usually paired with budget CPUs. You'll need to consult the manufacturer of your specific motherboard to find out their power delivery ratings.
Your 12400F keeps running at the lowest 4GHz frequency regardless of your actions.
Change your power configuration. If you decide to go down, just let me know. I’m not sure how much you saved in power usage—even in terms of cost. @Needfuldoer Yes, I get that. On the @chocolatekarma screen, it looks like his single cores hit 4.4GHz. I don’t know for sure, but I ran a stress test and my peak was 4.1GHz on a few cores. Maybe because I’m using balance power settings, which is unclear. I’ll try more tests. It’s pretty interesting. But the main point is, it’s not what you paid for. Still, it’s a big improvement over the i7 4770.
Only at the beginning of Windows it exceeds 4GHz, possibly because it's identifying just one processor core.
