I thought that was per chip ECC not per module? (May be wrong on that)

You’re right, and I was being imprecise. I was trying to convey that the functionality was entirely contained within the chip/module unlike traditional ECC which passes the parity data back to the CPU.

The parent said the chances of a single bit flipping are too high without it, they are, which is why it’s in the spec :) These densities wouldn’t be possible without it.

There are DDR5 modules with traditional ECC though, which the parent poster presumably meant.
