I have some 4gb ECC that came out of a couple Dell Poweredge 2970's not sure what type it is. I upgraded from 32 to 64gb in March of this year and cant remember what type. I just left work and seen this when i got home but I can get it to you if you can use it. I think I have 4x 4gb and 4x 2gb ECC memory. Post back if you think it will work and I'll pick it up in tomorrow AM and get it to you some how.
