[SOLVED] Ryzen 5 on B350 board: VCore, VDD, VID

[MrPipa94]

I've read a lot of threads about CPU voltage, both in general and for both different Intel and AMD (Ryzen) processors. Yet I fail to understand the difference between VCore, VDD and VID with my Ryzen 5 processor.

Relevant specs for my system:
CPU: Ryzen 5 1600X @ 3.9Ghz (V-offset set to +0.0375V)
Motherboard: Asus B350 F-Gaming
RAM: 16GB TridentZ RGB (Samsung B-die) @ 3200Mhz 14-14-14-34

Looking at what HWMonitor reports:
Idle / Load diff
VCore: 1.395 / 1.450V 0.055V
VDD: 1.425 / 1.363V 0.062V
VID (#0-5): 1.375 / 1.306V 0.069V


So to the questions:
Q1: Which (VCore, VDD, VID) should I be looking at for overclocking? What is the actual voltage to the processor? Can we get an explanation for each of these? (Or by all means a link somewhere where it is explained?)

Ryzen processors should be ran at max 1.40V for safe 24/7 operation.
Q2: Is this 1.40-1.45V max voltage for VCore? This is mentioned in a few threads but I find it hard to believe since my VDD and VID are already incredibly low.

Q3: Is the max safe limit for the voltage measured at load or also while idle? It would make sense that the max voltage should apply while the CPU is loaded, or can high voltage while idle also damage the CPU?

As you can see from my results above, the voltage plummets for the VDD and VID quite a bit. LLC is set to medium, going higher seems unsafe (GamersNexus had a video about LLC which recommends to never go over medium).
Q4: Should I still go higher on the LLC or should I lower the voltage so I get my VCore down, lower the clocks so the load is smaller which results in a lower voltage drop on VDD/VID?

Many thanks to anyone for any information

Let me start off by saying that HW is extremely buggy software. I still use it to monitor certain things but it is well known to report hilarious OC's like 9ghz, VDD incorrect readings. All you need to worry about is the Vcore reading. That is telling you what your CURRENT voltage is at. You can go into windows power options and set your plan to balanced. If you have cool n quiet turned on, you'll see that voltage drop way down like 0.8V when you aren't doing anything. Say you set your plan to high performance, then it's a 24/7 OC and it will stay at what you've set it too, namely the 1.425V which is what it looks like you have it set to in bios. I used to run my R5 1600 @ 3.85ghz / 1.375V 24/7 because AUTO didn't get good results until 2nd gen. I don't think you'll get any better results by going past 1.4V so i wouldn't go higher personally. You should also test lower voltage as well. If you don't need 1.4V then you're adding heat for no reason. I just like to do a run of Cinebench. If your OC is bad it WILL freeze no matter what. It's a great simple and very short test. Safe max voltage is for 24/7. While they say 1.45V is technically safe I never wanted to go that high. The 1600x really doesn't need that much power anyways. That's 8core territory. I've not messed with load line calibration since FX series so I don't know how relevant that is now.
