R20 I have scores normally fall between 7200-7300 3900x tuned system and I know of sister (near identical) system to mine with similar scoring and I'm sure you know that scoring in this is bound mainly to CPU horsepower and little to Ram. It can do better.
Not sure about voltage claims you state as reliable, however I don't run x470 board or stock cooler and there has been a lot of misinformation propagated on this subject, ie your reference to overvolting suggesting error by manufacture/bios, do you really think amd or asus want to cook your cpu for RMA process that you would win or is it more likely the posters talk rubbish?. I think they are wrong. Want to guess how many run on AUTO without issue .... many more than undervolt or read this misinformation (but if I was intel fanboy or troll hell yes I would post this, here cripple your new cpu 101 )
Typically I would leave that on AUTO and do and I own every generation of Ryzen including 4000 series on laptop. But I would set SOC Voltage, VDDG CCD Voltage, VDDG IOD Voltage, and the cLDO VDDP Voltage and of course DRAM Voltage if I was tuning my system. I have systems on which only use AUTO such as my 1800x is AUTO everything as it now my NAS/Plex Server and it does not matter, it is overkill for the job it does, been running that way since launch and still not dead or see above 45 on most days on a stock cooler.
For RAM, you want to use lowest DRAM voltage that does not result in errors, as this returns the best overall speed from RAM modules as well. Higher start voltage is only needed if you have as example 8d error and it might indicate higher voltage bump maybe needed during normal operation as well. Still not against the idea of using 1.4v as a start and dropping down if it was needed to get past memory training error that did not replicate in windows 10 use / memory testing.
Here is what I recommend you read.
Now tweaking this system your best off running with Ryzen DRAM Calculator which at time of post is version 1.7.3 / Thaiphoon.
To get baseline and then test things it has memory test to check for errors however you need to look to what is happening in the whole system as well, thus something like userbench (sample score https://www.userbenchmark.com/UserRun/25176144 ) is free and fairly good at setting baselines and then seeing what changes improve or make worse. After that it is crap, Intel funded and manipulates data sets and not worth wasting oxygen on. There are paid ones that are more evenly balanced but free is hard to go by. https://www.userbenchmark.com/ to get the download.
Lastly you mention temps of 61 degrees top out, this isn't all that important if the temperature is below throttling then it is fine, within design specifications, and will last (almost / within margin of error) exactly the same time as anything within design thermal specifications regardless of where within those limits the cpu sits or the duration. Lower temperatures does not increase or decrease that final failure time drastically, this is another popular myth to all cpu's not just ryzen. So my 3900x system never reached above 75 in summer with ambient temperature on the day inside reading 40 and I typically see 60-65 degrees in normal weather (however it is under AIO). Don't take this mean I don't value lower temps, they give you much wider margin of error before throttling and that is good and do make us feel better about investment protection (ie expensive cpus).
Hope you find this of help.

cLDO VDDP is reporting incorrectly on my x570 board and sounds similar issue for yours. In order to set 0.900 of Volt would read 900 in current bios which is why I think you could not set below 1.
