No, that remains a Xeon feature.

And on low end i3 chips

Yes, an example from 2017:

The latest i5 or i7 with ECC were introduced in 2014.

Now, does anybody know why i3 but not i5 or i7?

[spoonspoon]

Probably because there are no i3 equivalents in the Xeon line (no dual core Xeons) and Intel wants a low-end ECC supporting CPU.

Keep in mind that for at least the last couple generations, even though Celerons, Pentiums, and i3s support ECC you must use a server chipset like the C23x or C22x to actually get ECC on those CPUs.
