Is it normal for the 1700 to show it is running with a core voltage of over 2V when I have no overclocking going on and voltage in bios set to stock?

https://valid.x86.fr/scx49p

I made sure the bios was set to defaults, I dont have any overclocking software installed (anymore... uninstalled it to make sure)
Both CPU-Z and HWMonitor are saying my vcore is 2.1v fluctuating up to 2.17 every now and then. I am hoping this is just a motherboard reporting this incorrectly.

it was hitting 2.4 when I had it overclocked to 3500... with stock voltages and llc set to auto.

Any suggestions on what I should be trying or looking at?

Oh, my temps are sitting at 34 when idol and @46 under load.

Thanks for the tip. with HWiNFO vcore is showing proper numbers. It appears that cpu-z shows twice what it should be. I can sleep better today, thanks.

I have had issues with CPUz from day one 2 months ago, I would have thought by now they had gotten it straight but no dice.
In HWInfo the tru voltage is CPU SVI2 it's measured at the VRM so that's what your CPU is getting. I have found there's a fair bit of V_Doop in the Ryzen platform. Like setting 1.35V in BIOS gives 1.3V at the CPU

@Johan~

Does the cpu-z reporting differ from one operating system to another? And if so, which one is closest or most accurate?

I think it differs more board to board than OS. On the CHVI seems about the same win10-win7 ~ .05V on the MSI I was testing was closer to 0.03V still high though this is compared to BIOS setting. I just don't think that the crew at CPUz has found the right source to monitor.
