Difference between Sandy bridge FCLGA1155 & LGA1155 sockets

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).

  1. Yes it works.
    We have plga775 which is plastic land grid array 775
    We have fclga1155 that is flip chip land grid array 1155.
    Differences in flip chip is that :

    Quote:
    Processing a flip chip is similar to conventional IC fabrication, with a few additional steps. Near the end of the manufacturing process, the attachment pads are metalized to make them more receptive to solder. This typically consists of several treatments. A small dot of solder is then deposited on each metalized pad. The chips are then cut out of the wafer as normal.

    Yes it is work.But however according to some the bios wont recognize it however it would work.
  2. However ever since its start flip chip production i think all there cpu are flip chip.They would of course still work on normal lga 1155.
  3. Are you sure ? Cuz i plan to go in for i3 FCLGA115 and later upgrade to either a LGA1155 i7 processor or maybe even an Ivy Bridge as it too uses LGA1155.

    I want to avoid changing my mobo too.

    FCLGA = LGA. There are no differences between the two.

    As I said it may or may not work depends on the BIOS,
    If you havent flashed a bios before or are not famillar with bios setting please refrain on buying a fclga1155.
