The 30 second boots are memory training. The motherboard is basically training itself on how the DDR5 memory modules respond on every signal wire and it can be inordinately slow depending in memory amount. For whatever reason, AMD DDR5 systems are slower at it than comparable Intel DDR5 systems.
Update your BIOS to the latest version then enabled “Memory Context Restore”. The bios will then save the last training results and stop taking 30 seconds to start up.
Is yours a new AM5 socket based AMD system by any chance?
Yes, why?
I also have a zen4 cpu.
