A fair few X570 boards have 128GB support listed but it might not be all of them. Don't think any X470 or lower boards supported more than 64GB. But you'd need a pretty expensive 4x32GB set, maybe 2x64GB will be supported but I doubt it'd be cheaper.
Wouldn't be that much more to consider a Threadripper solution with 8x16GB sticks and a 1900X but still abit more.
Currently got the 9900k with 64gb 3000mhz (4x16) but my VM's (Cisco Call Manager cluster, Polycom Realpresence cluster, pfsense high availability cluster) are eating away at the ram.. I'm defo gonna upgrade to Ryzen 3 16 core but only if I have a 128gb option. So i'm trying to figure out what is my cheapest option is going to be. I know Ryzen cpu's support server ram but cant find any 32gb with 3000mhz+ speeds.
You'll get twice the bandwidth from a Threadripper setup and it's looking like the X570 motherboards will be in the same price ballpark as current TR boards, while you'd save a couple hundred £'s using 8x16GB vs 4x32GB, definitely worth considering for your use case I'd say. It's just a question of whether there will be 16c Ryzen 3 Threadrippers(Personally I think there will be because it's all of these high IO use cases where the TR platform really shines).

No! It's a Ryzen 9 part but is Ryzen 3rd Gen which is two totally different things, but to answer the question I was watching a video by Buildzoid today on the X570 Godlike and he was talking 128 gig of ram being supported
Yes FTLN that memory you linked is unbuffered, you can tell from the bottom bit of the spec list, when it says "Registered: No" this means unbuffered essentially.
I think the confusion from the point above is that Ryzen 3rd gen is Zen2, because Ryzen 2nd gen was Zen+, and so Zen3 will be Ryzen 4th gen. (Zen is arch, Ryzen is brand series). Then they also name their brand tiers Ryzen 3/5/7/9 to confuse things more.
