Taichi x370 5.10 bios made ram worse

Prior in beta 4.81 I was able to clock my corsair lpx 3200 m-die hynix at 3200 MHz with some custom settings like 16-18-18-18-38-56 and 1.38v and without tweeking I could clock it at 3066 MHz with just the xmp profile. Now nothing works, sometimes the previous stable settings shut down the system during post until discarded and I am forced to go back to xmp 2933MHz like I was last year with the first bioses. How do you manage to worsen the memory support with agesa 1006 is beyond me. I want to really throw this motherboard out of the window.
