Bought a Patriot Viper 4 3200 16GB kit to go with my Ryzen 5 1600 build, problem is they are unstable at default bios settings. System is unstable and I get WHEA errors also memtest86 is showing errors especially craploads of hammer test errors. However when I crank the voltage up to 1.25V from the default 1.2V everything is fine: no errors anywhere. Also I can run them with XMP@3200 with no problems, everything stable.
Bought the kit (PV416G320C6K) because I thought it was on Asrocks QVL list, however turned out only version 11BF2 of the kit was verified which mine is not.
So it looks the default voltages are the issue: at 1.2V they are unstable up to 1.25V and everything seems fine. And obviously with XMP they are running at 1.35V on which they are also rated.
So should I worry about this or just nevemind that default bios settings are unusable?
And when I say default I mean default, nothing is OC'd.
The mainboard has the latest AGESA 1.0.0.6b update.

Yeah that's what i've been thinking. The next pair might run with bios defaults but not much with anything else, that seems to be the case with lot of people. I asked advice from Patriot and they just offered to RMA them but not sure if I want to, lol.

I'm finding myself in a similar situation as you were/are in now. I have the exact same memory kit as you. It's the PV416G320C6K. ButI didn't buy this kit knowing anything about it at all except it was DDR4 and that is was the fastest DDR4 speed available at the time I bought it.

Fast forward almost 3 years to the release of Raven Ridge AMD 2200/2400G CPUs and the glowing reviews. So, I see that my Patriot Vipers are on ASRocks AB350M Pro4 QVL memory list for Raven Ridge so I go ahead and purchase my AMD 2200G/ASRock AB350M Pro4 motherboard combo. Already having my DDR4 memory chips from 3 years before. But the caveat, as you point out in your original post is, whether they are 11BF2's or not. This I still do not know to this day. How can you tell? My memory sticks are already installed in the motherboard and I don't really wanna bother with removing them. Is that number on the stickers somewhere or the packaging or can you find it through a special Windows application?

Anyhow, I guess I'm somewhat lucky, in that I can get this kit up and running stable @ 2800MHz @ 1.35V with XMP enabled in the BIOS, while I never could run these chips @ 3000MHz. I find it awesome that you can run yours @ 3200MHz which is actually faster than the rated maximum speed. Have you tried running them @ exactly 3000MHz? Or is that unstable for you?

Of course, me and you bought different CPUs so that's gonna play a role in the performance I can get on these chips versus what your getting. Also, like others have said. There's absolutely no reason at all to worry that default BIOS settings are unstable. These chips absolutely require 1.35V to run at their 3000MHz rated speeds. It would be weird and almost impossible for them to run successfully @ 3000MHz @ 1.2V. The newer memory chips coming out at 10nm are getting close to being able to run @ 3000MHz on 1.2V but you would see that on the packaging.
