Sorry, I was a little obtuse. What I was inferring was that historically, only higher-priced server chips from Intel had ECC support. In 2013, Intel launched the v3 lower-end Xeon E3s server chips that were closer to the price of the consumer Intel chips and offer ECC with comparable clock speeds. Of course, all of those only have 4 cores instead of 8.

Yes, all of the E3s support ecc, but Xeon's didn't always support ECC until the launch of the Xeon E3 as far as I can tell.

Xeon has implied ECC support for as long as Xeons have had integrated memory controllers, which is just a generation or two further back than the first Xeon E3 product line. Before that, ECC support was a function of the northbridge.

Hmm, perhaps this is a quirk of ark.intel.com then; it shows that (as an example) that the Xeon X5690 supported ECC, but the Xeon L5638 did not.

The list on WikiPedia also seems to imply that not all models did historically, perhaps this reflects the northbridge change?

There was the Xeon 3400 even before that. Trivia: it supported registered ECC, but only x8 chips and not x4.
