Everything new enough to use DDR5 has the DRAM controller embedded in the CPU, so we'd be talking about something more than just new motherboards.
I spent about 3 weeks trying to get 4x64GB DDR5 6400 working on an AM5 workstation. I never got it to run for more than about six hours at anything faster than 4200MHz, no matter how much I fiddled with timings and voltages.
Hilariously, that spare 128GB RAM kit is worth like $2000 right now.
