Hello MRewer,   It is actually a version 3 so it looks good:   Pn#G7WYD - ASSY,PWA,PLN,MZR,R710,MITAC,V3  
I have R710 server and I'd like to upgrade the CPU to Intel Xeon X5690. The motherboard part number is 0G7WYD. The service tag label shows roman II but the some parts might be replaced in example mother board.
Power Edge R710 --- Need to know if this Motherboard is Gen 1 or 2...
