> ECC adds significant cost Does it, though? I don't remember all the prices from when I was researching memory close to a year ago for a new PC, but one big notable difference between ECC and non-ECC I've seen is that almost all non-ECC sticks are overclocked. You buy something rated at 2667MHz, and you actually get is e.g. 1833MHz chips overclocked at that speed. Which makes them cheaper. But I'd expect non-overclocked non-ECC sticks to be that far in pricing to ECC sticks (well, apart from the obvious difference they'd have more chips). And because the market is focused on cheap non-ECC sticks, they don't do cheaper ECC overclocked sticks, but there is no reason they couldn't make them. There aren't that many ECC unbuffered sticks already, it's easier to find registered ones. Essentially, the market is skewed by Intel not supporting ECC on non-Xeons.
