As an alternative, perform a budgeting exercise whether to go for a motherboard that takes your Xeon, but has ECC RAM and Intel network.
Before writing to you, I had read both ASRock published specifications http://www.asrockrack.com/general/productdetail.asp?Model=H87WS-DL#Specifications and the manual ftp://66.226.78.21/manual/H87WS-DL.pdf but I noticed only that you can insert ECC RAM modules, not that ECC capability would be used... What did I miss?

Okay so new motherboard...
I was thinking this one: http://www.supermicro.com/products/motherboard/Xeon/C220/X10SAE.cfm
Is there another you could recommend? I have 6 drives, 16GB RAM 4x4, LGA1150 Xeon, and I would like 2 NICs for LACP
