That could be a memory training issue. Using 256GB listed as compatible with the Supermicro motherboard my EPYC server boots in a minute or so. If i configure my workstation memory with weird timings it can take a while for the motherboard to figure out the remaining Auto-timings, possibly adding 4-5 minutes to the boot procedure.

But you don't have to, see my other post in the thread regarding my workstation memory.
