The QVL is NOT a list of all the memory modules that are compatible or friendly to your motherboard. ALL that ANY QVL list is, is a list of what THAT manufacturer actually bothered to take the time to test on that board with positive results. It does NOT even mean that the memory will RUN at the advertised speed, because they DO NOT check that. They ONLY check that that memory kit will initiate and boot AT THE DEFAULT CONFIGURATION.
If you look at the QVL list for most boards, you will see memory modules, not always, but often, that are higher speed than what the manufacturer even SAYS is possible to run on that board. That is because it CANNOT run at that speed, but it CAN run at speeds up to whatever the maximum the manufacturer has indicated and whatever the bios allows for. So QVL is good for some things, but it should NOT be the measuring stick you use when determining what modules to buy for your board.
The user verified list I linked you to is a FAR more reliable source for what has been found to actually RUN at the ADVERTISED speed by users in the wild. Also, 8GB is the very low end of the scale for what you want to see in a system these days. Also, there are no 2 x4GB kits with a CL14 latency, which makes it hard to find a very good module with a really low overall true latency.
If you can swing a little more for the memory, I'd highly recommend doing something like this:

If you cannot, then these would probably be the best option and I know these will work with your Ryzen system because I've used them myself recently in a Ryzen build on a mid tiered board.

And if that is still more than you can scrape together, then this too is 100% compatible.

Obviously, the 16GB kits are a lot more desirable than the 8GB kit, especially since there is only about a 35 dollar difference, but sometimes you gotta do what you gotta do.
