I'm not holding my breath for ECC support. My thinking is that if it could run ECC RAM with the actual corrections enabled, they'd be talked about that as a selling point. I'd sure like it with the 32GB I have going into this build, but I just went with "G.SKILL F4-3000C15D-32GTZ TridentZ Series 32GB (2 x 16GB) 288-Pin DDR4 SDRAM DDR4 3000 (PC4 24000)" for now, with the idea that I'll get a second of the same kit in a couple of years when it's half the price of today.
