I bought E5 2697 v2 12 core Xeon processor to replace it with my old 4 core processor. My tech says that he cannot replace it because it has different socket. How is that possible ? If you look on the owc site indeed the 12 core model looks different than the 6, 8, 10 core processors. But the site says the socket is the same. I made a photo of both processors the 12 core is the one on the bottom.
It’s the L3 socket. Your tech is incorrect. The new CPU should exchange nicely. Here’s how to change it yourself: Mac Pro Late 2013 CPU Replacement
