Use Ryzen Dram Calculator, just Google it, you wont get 3600MHz but you may get 3000 or maybe better.
I run 4x8GB Corsair LPX at their rated 3000MHz and they ARE mismatched, one kit is from 2015 with dual rank and 25nm modules the other kit is from 2018 and is single rank with 21nm modules. Hynix AFR on both. Still it works at 3000MHz, it wouldn't have without using Ryzen Dram Calculator as there are way too many memory settings in the bios to just have luck and happen to pick the right ones.
