Ryzen OC, fixed voltage?

So a few days ago I sold my old pc parts (mobo+cpu+ram in the specs) because I though I had received a good offer for them, and with a little bit more replaced it with the next Ryzen build:

Gigabyte AX370 Gaming 3
Ryzen 5 1600 AF
16GB 3200 Crucial Ballistix Sport LT

Also I read a lot of good things about a pretty inexpensive cooler that I didn't know much about, the Arctic Cooling esports 34 DUO, so I got one as well.

Since the stock speed seemed to vary quite a bit, and the temperature barely surpassed 45ºC, I decided to give overclocking a try. I had no idea of what I was doing so I tried to test things with Ryzen Master first. Turns out 4.1 ghz on all cores was achievable with 1.26v, I read that 1.35/1.375 is the max safe voltage for these chips, right? So I don't know if it's a good voltage but at least it seems I'm safe for now.

Then I went to the bios to set the oc parameters there, but did not find any vcore settings. I figured it out that I had something similar to add +0.xxx V or to reduce -0.xxx V to the current voltage, after a bit of testing I was able to set 1.26v there. But there is one thing: HWINFO reports different core voltages. Screenshot there's the 'Vcore' value that fluctuates between 1.248 and 1.272, which I would say it's the correct voltage. But that number doesn't change at idle, it's always the same and I don't know if this is safe for everyday usage. Then we have the value 'CPU Core Voltage' that shows 1.11v, what does this value means? It's obviously not realistic but I'm confused.

I ran an userbenchmark test and it seems everything is working how it should, it's stable and even I managed to understand how to use Ryzen Ram Calculator and set my memory timings following the fast preset (14-17-14-32) instead of the standard CL16-whatever that followed it. Everything is stable yet I still don't understand how overclocking works in Ryzen, but my main concern is the voltage staying at about 1.26v all the time.

Is there something wrong in my overclocking?

did not find any vcore settings.

There should be a menu called Advanced Voltage Settings where you can adjust VCore according to your boards manual.

Usually you should be able to set fixed VCore or adaptive/offset mode. With the latter two your VCore should change according to the VID. You can also define an offset there to add or reduce voltage to get your needed voltage.
According to your screenshot your VCore changes so no fixed voltage here.

This is the Advanced Voltage Settings, there isn't much to adjust here, as you can see all I did was to add a bit of voltage in the first value.

Some uefi bios have a easy mode, you need to switch to advanced mode and read your motherboard manual. There are videos on youtube as well.

your ryzen master tool should allow you to manually control the voltage if its supported.
but I think you cant control the voltage with your MB, only a delta value.
if you can, try to change your MB, this one appear to be very limited.
