Interestingly, the only vendor which sells 16GB unbuffered ECC DDR4 DIMMs seems to be Crucial: http://www.crucial.com/usa/en/ct16g4wfd8213

E3 DIMMs have always been rare and usually expensive; I wish Intel would enable regular registered DIMMs.

The funny thing is that they still so expensive when the x8 chips are so cheap.
