    Currently, my SZ 210pb has a T2300E processor. Its package type is, according to CPU-Z, is Socket 479 mPGA. So, I have a question.

    If I upgrade my CPU to an higher end Core Duo, do I have to use the same package type only? So, do I have to use only Socket 479 mPGA CPU?

    I am asking this, because I plan to upgrade to Intel® Core™ Duo T2600 (sSpec # is SL8VN), the package type of which is Socket 478 pPGA. This is the only T2600 mobile CPU. I checked Intel, and they do not have any Socket 479 mPGA T2600. As far as I know, the higher end SZ 2XX series uses T2600.

    Is this T2600 compatible with my vaio SZ? Does Socket 478 pPGA T2600 fit my vaio, although it has currently Socket 479 mPGA T2300E? Any advice will be appreciated.

    As long as that specific series of VAIO notebooks were sold with the T2600, it should work.

    PGA = Pin Grid Array. Those are designed to be removable, so it should be fine. Intel usually doesn't specify package types in their front pages, but you should be able to find PGA specs in their engineering or detailed spec documents.

    BGA, or Ball Grid Array processors are typically used in much thinner notebooks or ultra portables.

    Bottom line, there is no reason for it not to work AFAIK. Just make sure the mPGA package is the same (479 pins and either a Yonah (T1x00-2x00) or Merom (T5x00-T7x00) processor). Check the BIOS for info on if Merom (Core 2) is supported.

    Wow. What a quick answer. Great thanks!!

    So, even if there is a difference in package type of CPU, can my vaio SZ CPU socket, on which currently Socket 479 mPGA T2300E CPU is installed, fit Socket 478 pPGA T2600?

    The Core Duo and Core 2 Duo both use the same socket, so if you have a Core Duo, you can put in a Core 2 Duo and not worry about it not fitting. You will want to make sure that the BIOS supports the Core 2 Duo though; I would recommend going to Sony's support site, downloading the latest BIOS, and flashing it.

    Isn't Core a Socket-M?

    The Core Duo/Core 2 Duo use a Micro-FCPGA package that fits into a 479-hole socket; it is referred to as the PGA479M Socket. It is commonly called Socket M. ;)

    Thanks a lot for the advices. However, it seems that there is some misunderstanding. First, I do not upgrade to Core Duo 2. I am upgrading to Core Duo T2600.

    According to Intel, Core Duo T2600's package type is Socket 478 pPGA.

    However, my Sony Vaio SZ has a T2300E CPU. Its package type is socket 479 mPGA, according to CPU-Z.

    As far as I know, pPGA and mPGA are different. In micro PGA, pins are more dense than pPGA. So, in theory, I thought they are NOT compatible.

    However, an high end model of VAIO SZ 2XX (mine is sz210pb with t2300E) has an T2600 cpu. As far as I know, T2600 CPU is only one kind, the package type of which is Socket 478 pPGA. In addition, all SZ 2XX use the same motherboard. So I am confused by this.

    Is this means that my vaio, which has socket 479 mPGA T2300E, can be upgraded to Socket 478 pPGA type T2600?

    This is my question. Anyway thanks!

    It seems that I need to clarify my question. So, are socket 479 mPGA Core Duo and Socket 478 pPGA Core Duo compatible for upgrade?

    All Core Duos use the same socket; it has 479 pins, not 478. If you already have a Core Duo in your laptop, then any Core Duo will work. You can check Intel's white paper for the Core Duo:

    Has anyone upgraded their VAIO SZ Core Duo cpu to a Core 2 Duo? I have the sz220 and am thinking about doing that at some point. Wonder if it has been working.
