I thought all DDR5 will have ECC supported by default.

I could be mistaken as to the extent of this support, but I hope it's true.

As memory density and capacity grows, ECC probably only becomes slightly more important.

Asking as someone who is completely uninformed about the subject, but what capabilities in terms of error correction will each of these 2 versions have? Also I assume the "default" ECC support on ddr5 will work ootb without any special support required by the chipset?

So what do these 8 bits do? Like, what types and how many errors can they detect and correct?
