Can my cpu be replaced ?

Hi all I've got a Lenovo Z580 with a Pentium B970 , 6GB DDR3 and a nVidia GT640M . I want to upgrade the cpu to an i7 2620M . I saw that both CPUs were socket G2 (rPGA988B) so could I replace the pentium or the computer won't handle it?

  1. You will have to contact Lenovo to be sure.

    However. Why not save a few and get the I5. The I7 (non-qm) are not quad cores. All of the CPUs that are dual cores UNLESS they have the QM part at the end.

    I say the same thing every time,

    I'll come out and say that changing your laptop CPU honestly isn't worth it.

    I'd instead recommend you upgrade to an SSD, as that actually improves performance which you can notice on a day to day basis, which you can carry onto other systems as well.

    If you happen to move your laptop all the time, and need durability I'd than recommend an Intel SSD, as they have a great reputation of reliability. If your looking for value, look into Crucial or Samsung SSDs. Plextor and ADATA also make good SSDs.

    I'd also recommend upgrading to Windows 7 or 8 if you plan on upgrading to an SSD.

    Let me know if you would like some help.
  3. Any i7qm is going to cost you $300+ easily. Not worth it. Better off buying a new system.

    PCDave is right about an ssd. I bought my wife a wimpy little 11" Acer laptop with 2GB ram and a 1Ghz AMD dual core. I put a 4Gb stick in and a 180GB OCZ ssd and that little laptop flies!
  4. Actually I can get the i7 2620M for 90$ and since the sockets are compatible should the new CPU work . Also it's a spontaneous upgrade because it's a great deal .

    Yeah, I think it should work as its the same socket.

    You can find the steps here:

    The processor upgrade will help a bit, especially in video editing applications, and a gaming increase as well.

    I'd still contact Lenovo support, which can be found here:

    Good luck.

    I still stand by my SSD recommendation though, if don't have one: get one now.
