When using Hwinfo64 with C-states on, C1E support on, and manual voltage set to 1.25V in my BIOS, under the Vcore reading in Hwinfo64 I'm seeing fluctuating Vcore as if manual voltage was turned off. This doesn't seem normal. My understanding is that it should stay at the voltage I set it at regardless of power settings. CPU-Z shows a fixed core voltage under these same settings.
If I turn C-States and C1E support off, but leave on manual voltage, the Vcore stays set at 1.264V in Hwinfo64. In Hwmonitor the Vcore seems bugged and stays at 0.888V no matter what, but the VIN7 value always corresponds to the Vcore value in Hwinfo. CPU-Z shows a core voltage of 1.252V.
I noticed that when stress testing using Prime 95 26.6 I see the Vcore value in Hwinfo64 and the VIN7 in Hwmonitor jump to 1.28V very quickly, while CPU-Z shows 1.252V. I shouldn't be seeing these kind of voltage increases because I'm using the older version of Prime 95 that isn't using AVX instructions right?
So, which readings are correct and which aren't?
