Second hand PC dealers in my country (Turkey) used to put together affordable gaming rigs using old Xeon processors a couple of years back. That's why my first guess was that if it was a Xeon. I think Xeon processors also have special motherboards, so you can put TWO processors on some of them. That was a huge selling point for computer nerds like me. Wikipedia says "Because of a hardware limitation not fixed until Ivy Bridge-E in 2013, most older Intel CPUs only support up to 4 gibibit chips for 8 GiB DIMMs". The E5-2609 is at the generation of sandy bridge. So you probably bought the Xeon to support 32GB :).
