New 1600X system Vcore going extreme high for my taste

[Aleximus96]

Hello, recently i built a new pc

X370-F Strix
R5 1600x
16GB Ripjaws V 3000

So when idling or doing basic tasks, the cpu voltage (CPU VDD in HW Monitor) shows that it goes to up to 1.5V and drops to 0.39V when idling due to xfr, i would really love to run 1600x at stock, like i don't mind down clocking when it's not used, but i mind auto OC-ing when it "needs couple of 100 Mhz more". You can say that i don't feel comfortable with that voltag. I would really love if i could set some lower max voltage, so i don't experience these voltage spikes. the temps are not a problem, and the cooler is hyper 212 evo rank (almost identical, just different company).

Can you guys help a brother in need? Thanks.

First I would double check the data in AMD Ryzen master in case HW Monitor is not providing accurate data.

Just downloaded the Ryzen Master, voltage same as in HWM. :/

You should be able to disable XFR and Precision Boost features in the UEFI. My ASUS ROG Strix X470-I has this feature I noticed setting up my new Ryzen build. This should limit voltage needed as it won't boost to the highest binned frequencies.

I have red that on my mobo there is only option to disable XFR by manual OC, which i do not plan on doing. i have seen that here is no off option as well.. :/

I suppose you could try a manual vcore setting, even an offset voltage. Limit multiplier max perhaps. Be aware though in my testing, even without OC on previous R7 1700 and C6H I sold, when I set a manual vcore, it limited CPU frequency to around 2Ghz for some reason. When I set back to auto, frequency returned to normal.

Yeah, it kinda irritating, nevermind i will leave it on default untill someone can clarify this a bit better.
Thanks anyway.

Update :
After sterssing the cpu with Cinebench R15 a acouple of times, i have noticed that all cores go to max turbo of 3693 which is close to advertized 3.7 Ghz onall cores load. next the CPU Voltage fluctuate between 0.4000 - 1.500 V on idle doing random things, but not more than a couple of seconds on 1.5V.

While all threads are being stressed, the Vcore doesn't go above 1.200 V on all cores.

Here is the screenshot of HW Monitor after few runs of Cinebench : http://prntscr.com/k86y1y

That's actually normal under full load, the large voltage drop. I also get spikes nearing 1.5 on my 2700X on light loads. I believe there is a technical video from der8auer I think. https://www.youtube.com/watch?v=_XGhpKHWYAg

Think this is the one I've watched before.

I'm retarded....

I have seen that clip on release but forgot about it.

Thank you.

It is a helpful video. Glad it shed some light on the situation for you. Learned some things myself from that one.
