Question about RAM compatiblility

Compatible, yes.

3200, meh, don't get your hopes up.

They're Hynix A-die. The good thing is they are Single Rank, Single Sided.

I would try the 1.0.0.6 BIOS first as Hynix seem(s)(ed) to prefer that BIOS rev. over 1.0.0.6a BIOSes.

If not what is the lowest frequency i can get it to for it to boot stable?

What, a TridentZ memory model with Hynix memory chips? Not Samsung B-die?

Of course, G.SKILL does only include Intel systems in the QVL:

What's the lowest frequency/speed you can get it to boot stable? We can see that is 2133.

I assume you mean what is the highest frequency you can get it to boot stable, if not at 3200?

Usually that is 2933 for Samsung B-die chip memory, if not more. 2667 is the Ryzen max specification. Which CPU are you using?

 We'll need to see how your model cooperates. It's very difficult to predict memory speed potential with Ryzen, if the memory does not use Samsung B-die chips. You'll just need to experiment with memory speeds and timings and see what happens. The XMP profile is no doubt designed for Intel systems so some manual memory tweaking will be necessary for higher speeds. The SOC voltage set to ~1.1V from the default 0.900V, for example.

when i was looking it seems samsung dies were 3200 and above and at 3200 needed to be cl15 or cl14,,,,,3400+ etc was using b dies
(that applies to the 8gb sticks)

In case all of you have not seen these new G.Skill:
FlareX
Enjoy, John.

BTW, just saw that this new memory is Threadripper/X399 only and only 4 channel.  Enjoy, John.
