So I recently put together my first PC ever, and while I originally was putting it together as a 2700x build, I was quickly informed and repeatedly reminded by everyone I asked for help with the build to "Forget the 2700x, wait for the 3700x. You'll be much happier"
So I did. Oops. Now I'm afraid to even use the thing and I'm quickly regretting buying it, plotting out how to return some of the older parts that may be past their return date, send AMD's parts back, and considering spending the extra money necessary to create an Intel build out of pure spite.
Before I continue, I wanted to go ahead and get this out of the way. I have read AMD Robert's post about their "Final word" on Zen2 voltages. I have followed his instructions down to the letter, I understand his explanation about the observer effect on the processor by some monitoring software, so I followed his instructions about using CPU-Z ONLY with nothing running in the background to check my voltages while following his steps and nothing has helped.
I have a Ryzen 7 3700X build. My idle voltages sit at 1.4V+ constantly no matter what I do, with the occasional drop to 0.9V. My core temps fluctuate massively, PBO is WAY too sensitive, and without having to look very hard I find that others are having this EXACT same issue.
Let me repeat for clarity: My voltages do not "occasionally" go to 1.4V+, they SIT there CONSTANTLY, at idle, when I'm doing absolutely nothing.
CPU temps fluctuate a massive 20 degrees between 30c to 50c nonstop at idle, but settle around 50-60 under load, with my highest observed peak at about 73 degrees.
So the temperatures I've observed seem to be in a safe range, while still being completely nervewracking to someone who isn't used to it
PBO is so sensitive simply moving the mouse will send my clocks to 4.2GHZ and my fans will spin up and not stop until I do,
