This series used either Intel Core i5 (2500S, 2400) or Core i7 (2600) Sandy Bridge.

I would stick with one of these.

I understand that but that's not the question.

I have an i3 here i3-2120. I'm not looking for anything amazing, just want to boot up to use target mode for second screen.

Im just wondering if this i3-2120 would work on this board.


@gersrt - Sorry no, the systems firmware was not setup to support it.


Ahh sorry Dan. Now I understand thanks.
