PL1 & PL2 dynamic values too high, when applying limits to the CPU.

Hi and happy new year. :)

No problem here, it's just for understanding.

I noticed something strange in HWinfo when I manually apply a CPU limit on PL1 and PL2.

As soon as the limits are applied, the dynamic PL1 & PL2 values displayed are relatively high for my processor.
In windows power mode :
  • Best energy efficiency : Hwinfo display PL1 50 W / PL2 60 W - ok
  • Balanced: 80W / 105W - ok
  • Best performance: 90W /115W - ok
  • Applied limit CPU 40W-70W for example : Hwinfo display PL1 115W / PL2 135W (?)

My CPU 12700H obviously cannot operate at these values and I would like to understand why HWINFO displays such high dynamic values when I modify PL1 and PL2.
Shouldn't Hwinfo display the manually applied limits in PL1 and PL2 (40W and 70W in my example)?

Those dynamic limits are maintained by BIOS during runtime and Intel DPTF. So it could be a bug in BIOS, HWiNFO just reports the actual values.
