Cpu intel lga 1156 socket compatible to lga 1155 and 1366

Dear sir/madam

My mobo is h55mxv that supports lga 1156 socket intel cpu and the current processor is intel core i3.
I'm wondering whether i can upgrade it to i7 2600k lga1155 or i7 980 lga 1366. Should i also upgrade my 2gb ram and 430w psu as well?
Your precious answer would be very much appreciated.
Thanks hips.

  1. Welcome to Tom's Forums! :)

    In short no. The sockets are not compatible with each other, and if you placed an i7-2600K in your LGA 1156 MOBO it will damage the CPU :(

    It's time for a new MOBO. edit: ANY Sandy Bridge 'K' unlocked CPU should be placed in either a P67 or Z68 LGA 1155 MOBO the other LGA 1155 MOBOs {Motherboards} cannot OC {Overclock} either the i5-2500K or i7-2600K CPUs.

    Good Luck!

    Forgive my ignorance. What about placing Intel CPU CORE i7 980 / 3.33GHz / 12MB CACHE/ LGA1366 in LGA 1156 MOBO? If ok, should i also upgrade psu and ram? Thanks
  3. The LGA number is now many pins the CPU or socket has. They have to match for them to be compatible.

    An LGA 1366 mainboard has to have an LGA 1366 CPU.
    An LGA 1156 mainboard has to have an LGA 1156 CPU.
    An LGA 1155 mainboard has to have an LGA 1155 CPU.

    For your LGA 1156 mainboard, you can buy an LGA 1156 CPU to use.

    You MUST MATCH the socket/Pins MOBO with the socket CPU. Just for example, the voltage of each CPU Pin is different, the pathways of processing are different, and in the case you listed the i7 9xx has 210 too many pins like the square peg in the round hole. Won't work.
