This post by AMD should have some info on voltages -

Indeed, and is the basis of my point that AMD has not given information on "safe" static voltages. So continue with caution.
It is perfectly okay if your CPU is periodically using 1.4-1.5V to achieve boost frequencies, and you should see dips into sub-1.0V as the CPU goes into idle. These dips may be brief, and that's okay. Load voltages of around 1.2-1.3V are perfectly okay also. This is the processor working as expected. Ryzen is a highly dynamic system, with up to 1000 voltage and clockspeed changes every second. You will see a lot of bouncing around as you work with your system.
I anticipate that many people are now trying Ryzen processors for the first time (because they're awesome), and may not understand what to expect versus whatever CPU they had previously. You want to know if what you're seeing is "normal," but may not know what "normal" looks like. I get it! I want to assure you that the CPU needs voltages to boost, and voltages of 1.2-1.5V are perfectly ordinary for Ryzen under load conditions (games, apps, whatever). Even at the desktop, Windows background tasks need love too! You'll see the CPU reach boost clocks and voltages, too. But if your voltage is well and truly stuck, that's what I'm trying to troubleshoot.
