According to Crucial,

Designed with on-die ECC (ODECC)8 at the component level for long-term stability, Crucial DDR5 is engineered to maintain the same reliability as the previous generation, even with the rigorous demands of next-gen computing.

What does this mean?

Looking this up I found this

A: No. Crucial DDR5 Desktop Memory is non-ECC memory. The ECC as it pertains to RDIMMs, LRDIMMs, ECC UDIMMs, and ECC SODIMMs is a function that requires additional DRAM at the module level so that platforms such as servers and workstations can correct for errors on individual modules (DIMMs). On-die ECC (ODECC), however, is a feature of the DDR5 component specification and should not be confused with the module-level ECC feature. Crucial DDR5 Desktop Memory is built with DDR5 components that include ODECC, however these modules do not include the additional components necessary for system level ECC.

You can read more about this on the Wikipedia page for DDR5. Seems ECC protects the request anywhere en route to the CPU. And ODECC protects the request only on the RAM itself.
