Sandy Bridge upgrade Difference between FCLGA1155 & LGA1155

Is there any difference between FCLGA1155 and LGA1155 sockets? Does a FCLGA1155 processor (like the i-3's) need
a mobo with FCLGA1155 socket or will it work even on one with a LGA1155 socket and vice versa.

What will be the impact if one tries to upgrade from a FCLGA1155 to LGA1155 processor and vice versa.


While researching on Intel site I realized the entire i3-2100 series, i5-2390T AND i7-970 all use FCLGA Socket
while the rest of second generation processors are LGA1155 (i5-2390,2400 & 2500 series and i7-2600S).

    FC just stands for flip chip, don't worry about it, it's the same socket.

    All of those chips you mentioned above use s1155 motherboard EXCEPT the i7-970, it uses s1366.

    s1155:

    i3-2100
    i3-2100T
    i3-2120
    i5-2300
    i5-2400
    i5-2400S
    i5-2500
    i5-2500K
    i7-2600
    i7-2600K
