Asus Prime b250m plus, RAM compatibility

[Slayery777]

Hello, I have encountered such a problem that with 64gb RAM my computer is not stable, it can sometimes start only on ~10 tries or run with errors at 2133mhz (I have a KF432C16BB1K2/32 kit on nanya memory and another 2 KF432C16BB1/16 on samsung memory, I tried increasing the timings and increasing the voltage on the ram individually all sticks work perfectly and on the motherboard all slots work). Can this be fixed by modifying the bios? I suspect it may be because the sticks are dual ranked or because of different memory chips, but not sure.
