Everything is on stock and my cpuvcore goes from 0.8v to 1.5v+. If I use AMD balance power plan or high performance it never goes lower than 1.25v. Is this normal behavior?

CPU RYZEN 7 1700x
MOTHERBOARD GA-AX370 GAMING K5 (BIOS F5a Agesa 1.0.0.6b)

Hmm well according to cpu-z the core voltage of Ryzen 7 1700X (on an ASRock X370 Professional gaming) also running at stock fluctuates between 1.152 and 1.386. Hitting 1.5V seems a bit high on stock settings unless the giga-byte board is doing some sort of auto overclocking
 


Where did u find your information? I just saw this post : https://wccftech.com/amd-ryzen-cpu-gigabyte-x370-damage-burning-bios-update/ and I can't tell if its normal behavior or not. My Cpu temps are pretty decent though. Using Noctua D15s and they never went over 60 celsius during gaming. I don't know if I should flash to another bios.
 
Oh sorry that is from my system. I also own a Ryzen 7 1700X. Cpu-z and Ryzen Master gave me the Voltage information. I run my system at stock (haven't felt like Overclocking it yet) and got the voltage information while running my system at idle, 1 core load, and all core load (cinebench).
 
Likely false readings. Both the UEFI and Windows software(several) read CPU, DRAM, ect. incorrectly. I have a 1700 w/ Crosshair VI Hero. Using a DMM, the voltage points on the motherboard show accurate readings in manual, and likely auto voltage. For example, a manual 3.85Ghz OC required 1.38v for me. The DMM would read 1.39v full load in real time, while software showed around 1.5.
 


At least to me CPUID HWMonitor, CPU-Z and AMD RYZEN MASTER showing these high voltages 0.8 up to 1.55 within few seconds. The voltages are around 1.2-1.4 constantly.Overmore RYZEN MASTER AND CPU-Z showing a constant 3.5 GHz cpu, isn't it suppose to be 3.4? I don't get why it is 3.5 GHz
 


3.5Ghz is due to AMD's XFR Technology which allows your CPU to clock up 100Mhz from the Rated Clockspeed as long as certain conditions are met. (Mainly decent temps which your cooling solution allows for).

 


Well I read that XFR activates only on 2 cores but in my case ALL cores are on 3500MHz constantly.
 


It can activate under any condition. The 2 core one allows it to reach a maximum frequency of 3.9Ghz and 3.5ghz all core. (from the 3.8Ghz 2 core and 3.4ghz all core).
 


Oh I understand now, I misread it probably. But still my core voltages go up to 1.55 hopefully I will get and asnwer to that.
 
I get the similar readings in same software as mentioned earlier. This is what led me to use a DMM since my board has the voltage points. I seems to me based on reviews and the data I was seeing in my own searches that this situation is common w/ Ryzen setups. Even the typical Youtube reviews get the same readouts if you look at their monitors in the background during the review. I'm guessing AMD platforms calculate temp & voltages differently, and it's just not accurate in most readouts. Still odd that the UEFI itself also shows this. Again though, the DMM was right on, and that's far more trustworthy than software. The 1.55 you see is really 1.45 at max I'm guessing, and only for fractions of a second from XFR doing it's job. Also, XFR does boost all cores. Even my 1700 is rated for 3.0Ghz all cores, but floats around 3.2 all cores if conditions are right.
 


Today my CPU VCORE HIT 2.0004 https://imgur.com/9Fimvwo . Is this for real or misread from software? Overmore my CPU fan maxed but my temps didnt pass 60 celcius. All happend during game.
