Should be about 1/8th more since it's just a 72-bit bus for carrying 64-bits data and 8-bits check. Or rather, your dimm will have 9 chips instead of 8.
How they get you is Intel will sell you a xeon which is the exact same die as an i5 in a different package for more money.
Depends what you need - you can pick up older gen Xeon chips for cheap and the performance often isn't that much worse than modern consumer grade stuff. If you're looking to build a consumer-level NAS or home server, Avoton is pretty cheap and takes ECC RAM.
Unfortunately, Avoton might just suddenly stop working on you.

Some i3s support ECC: 7th gen: http://ark.intel.com/products/97125/Intel-Core-i3-7101TE-Pro... 6th gen: http://ark.intel.com/products/90731/Intel-Core-i3-6300-Proce...
It should be 1/8th more, plus a bit for the scrubber. But in practice ECC memory is "enterprise priced" so it's more like double.
Should we do a Kickstarter to manufacture our own DIMMs? Its an easy design and I hate donating to some corporate gross margins. Maybe enough people feel the same.
