I'm really curious what you found out since last year. I have a z790 ddr5 Tuf gaming board waiting to get put in a 4000x case. I also have a b660m that I'm throwing together too soon for fun
I know I'm very late to this question but I just got the extreme ddr4 64gbs today and I'm actually kinda upset that I can't run my 3600mhz any higher than 3200mhz without crashing. I have the Tuf Gaming z690 board. I switched from Corsair dom platinu...
