Does the on-die ECC function of DDR5 memory require motherboard support to work?

Yes, a DDR5 motherboard should support it.

By the way, DDR5 on-die ECC is not the same as real DDR5 ECC RAM.
DDR5 on-die ECC fix errors found before data is sent to the CPU.
Also overclocking RAM could disable that feature.

Yes, a DDR5 motherboard should support it.

Do you mean that it is possible that a DDR5 motherboard does not support on-die ECC?

If the RAM is overclocked it might not.

If you actually need ECC RAM --the vast majority of consumers don't, even if they think they do -- then you want to get proper hardware rather than counting on DDR5. And if you don't actually need ECC RAM, then it doesn't really matter what DDR5 does. It's basically a non-factor.

all ddr5 has on dieecc , it doesnt need any mainboard support as its just internal ram correction, its not full ecc ,
full ecc is reserved for server market, it has notch placed at different place then consumer ddr5, so you cant slap ddr 5 ecc into ddr5 non ecc mobo, as it wont fit

Is it possible for a mainboard to disable DDR5 on-die ECC? I have not found that it is possible (at least without overclocking).
