Mac Pro 5,1 X5690 ES

[Pandanl]

So I got a small upgrade, going from dual X5680's to dual X5690, all is working well butt....

Under Windows when I run CPU-Z there is a difference in specification between sockets, one has ES after the cpu name. I did not know what it meant and looked it up. It seems like ES stands for Engineering Sample and it is illegal to sell those because they are property of Intel.

Did anyone else get a ES and did you run in to problems along the road? I bought it in a pair on eBay, and it is nowhere mentioned that it is a ES.

Just let it be, or let them send a other one?

Socket 1:

Socket 2:

I don't know first hand, but I've read from others that the ES is sketchy and should be avoided.

Have them send another one. You do not want an ES chip.
