Agreed, my DIY NAS with ECC DDR4 has ran for over 5 years and I have 0 ECC errors in that time.

Something must be very wrong with OP's setup. Perhaps the RAM has been overclocked too far.

Well that's DDR4. Apparently DDR5 was made with tighter tolerances and less safety margin, which is why many people argue ECC should be mandatory in DDR5 - it actually relies on it.
