Question AMD APU R7 5700G Voltage too high

Hello guys,

While discussing with a friend about OC, I actually took a look at the Voltages of my CPU which was not OCed it runs on stock settings.

VDDCR is on Auto but I see in HWinfo and HWMonitor and AMD Ryzen Master that the peak Voltage is at 1.47-1.49 while doing nothing. Now after that discussion I found out that high Voltages will reduce the life of the CPU faster and I don't want that.

Here is a screenshot of the Info in HWMonitor Imgur: The magic of the Internet

So my question is if this is normal and there is no harm or should I get in BIOS and change it from Auto to Manual and input a lower Voltage?

I have a 5600G.

Ran Prime95 small FFT and HWinfo on a couple scenarios:
1 core/2 threads, 4.6GHz, 1.44V
6 core/12 threads, 4GHz, 1.2V

I don't use Ryzen Master. I just do the settings in BIOS.
I have PBO curve optimizer at -20 for all cores.
PBO boost limit set to +200MHz (hence single core of 4.6 being 200MHz greater than the advertised 4.4GHz max boost for the 5600G)

Its normal to see voltages like that at idle, as the CPU boosts a core here and there, you will see voltages up to close to 1.5v, at full load it should be quite a bit lower, and some boards do like to be a little more aggressive with PBO, you got nothing to worry about. My 5800x jumps to 1.48 at stock PBO settings, its how these CPU's work, I sit around 1.2v at full load.
