1st AMD build: Trouble finding compatible RAM Kit for ASUS X570 mobo

They probably are validated on either one of the test systems. I'll give an example, you'll select a FlareX model for an AMD build, and TridentX for an Intel build. Memory makers take you through those pages when you look for ram on their websites. That is what it is for.

When you match the model, all associated kits will work, but your motherboard may still not be strong enough since they have seperate vrms for ram. It might require a higher dram voltage, or a higher grade motherboard per se.

So, I need to research the VRM of the mobo to make sure it can handle the needed voltage of whatever clock speed I'm looking to achieve?

No, that is essentially consumer motherboards having limited support. What they are telling you when one kit works and another(say 32/64Gb) doesn't is that it is a question of motherboard compatibility at this point eventhough it might be a verified kit for your cpu system. Usually the trick is to increase dram voltage a notch which doesn't hurt anybody. It is unofficial that point, but who cares? Still, when purchasing it is best to pick the right ram to match your cpu, so timings won't trouble you.

Apart from tRFC, I think automatic dram timing can be left to the motherboard's utility that it ships with, they can sort tertiaries quite natively from what I've heard.

Buy a kit, it will work. Buy just about any 3200-3600 kit. Don't make this more difficult than it needs to be.

You can go with both options, selecting from the motherboard's memory compatibility guide, or the dram manufacturer's system preference guide which I suggest more preferentially. Motherboard lists are deemed to work, but suppose you replace the dram on another system, in that case you are better of knowing which system the ram is provisioned for.

That makes sense. Go for CPU compatibility (i.e. Don't buy an Intel rated kit for an AMD). Thanks for clarifying.
