I mean, a motherboard which supports TWO cpu's. For example if you want a equivelent to a i7 extreme you go for Xeon, but if you want two i7 extreme's you can't do that on one motherboard, thus having to switch to a Xeon and combing it with another Xeon!
As IntelEnthusiast pointed out to you, you need Xeon processors that have the embedded logic to run on dual socket motherboards. I7 processors don't have the extra logic required and they just won't work.
