I am not sure we can answer this question. The driver will adjust the voltage as necessary.
Please...read some of the similar posts.
Chances are your using, or have installed, Asus tweak. Get rid of it and/or any other third party graphics controller, as they conflict with Wattman/AMD.

I figured out the issue and a solution.
I have an Asus GPU, so I had the Asus GPU Tweak software installed. After installing the update and watching what happens on reboot, I discovered that the crash happened as soon as GPU tweak started, and that it was accompanied by a message about wattman being reset. I knew I had a slight "over"clock on my GPU, but I didn't even think about that being the cause of it. I booted into safe mode, opened up services and disabled the ASGT service (Asus GPU Tweak). When I restarted.... everything worked properly! I then uninstalled the software. Looks like I'll be doing all my adjustments through the built in AMD software from now on.......
