Looking for memory for FreeNAS build.

I have an old Asus Crosshair II motherboard with a AMD Phenom II processor. I would like to use it for a FreeNas box. I've used the memory finder, but there is no designation that shows whether the memory suggested is ECC (which is what I need for the ZFS file system in FreeNas). Any suggestions, hints, etc..? Thanks for looking!
