Glad to know it's working for you two! Do you mind sharing a screenshot of your timings/settings via ryzen master, ram info and latency from aida64/dram? Will be helpful for other members to see as a reference!
Sadly, I bought x570 Taichi also based on the review saying it's T-topology, knowing that I'm going to use it with 4x16GB dual rank RAM. Mildly disappointed there. There were cheaper alternatives with all the features I wanted.
In the end it worked as expected. 4x16GB (Hynix DJR) at 3600CL16 on stock voltage (just applied XMP profile). I'm sure there's room for improvement, if I start tinkering, but life is too short. I made my peace with it. Whole system is rock stable, does not overheat even when tortured and plenty fast (I know, I know - never say these words here).
