Intel has been pretty intent on making ECC server-only. I used their HEDT platforms for years and never had ECC. AMD is much nicer about the thing; if you want to use ECC on their HEDT platform, you can if you want. It's not super supported, but it's also not a $5000 upgrade. (Though my understanding is that ECC is mandatory for the current generation of Threadripper? That's great!)
