    Can I upgrade my processor to one that has a higher FSB?

    I currently have a Core Duo T2500 2ghz and I think my FSB speed it 667mhz. Can I put in a Core 2 processor(T7800) that has a higher FSB speed?

    In other words can I put the fastest Core 2 processor and use the extra speed?

    Why don't they make the FSB speed the same as the processor??

    Ok thanks for the link, but it just left me more confused.

    From what I read, first thing I have to do is see what the max FSB speed my board supports. How do I do that?

    And then once I have found the max number, I should stick to processors designed for that speed, otherwise a faster processor designed for a higher FSB might actually perform slower than a lower rated processor designed for the same FSB as my board??

    Am I on the right track?

    Thanks again

    no you cannot upgrade to the T7800 (It is socket P)
    The T2500 you have is a socket M processor.
    The T2500 is a yonah core, and some of the older laptops for socket M only supported Yonah's. if that is the case, you can only upgrade to a T2600/T2700.
    If your chipset supports socket M merom processors, you can upgrade to a T5300, T5500, T5600, T7200, T7400, T7600

    Please download cpu-z and tell us what chipset your ASUS has.

    The chipset will be the 945GM/PM. And yes, T7600 is the limit (considering that Core 2 Duos are supported by the BIOS).

    A Socket P CPU won't even fit.

    What about mine? I am interested as well...

    CPUZ says:

    Intel Core Duo T2500
    Codename: Yonah
    Package: Socket 479 mPGA
    Technology: 65nm


    Chipset: i945PM

    What exactly tells you the compatibility?

    Chipset tells you. The funny thing about Intel is that they change their chipset or socket with each revision of the Centrino standard, and sometimes both.

    Here's a quick reference, just off the top of my head (in brackets is the maximum FSB):
    Socket 479 - 855/915 chipset - Pentium M (400/533 FSB)
    Socket M - 945 chipset - Core Duo/Core 2 Duo (667 FSB)
    Socket P - 965 chipset - Core 2 Duo (800 FSB)
    Socket P - 45 chipset - Core 2 Duo (1066 FSB)

    So basically if you want to know what cpu's are supported, you need to know three things.
    1) the socket used. You can only upgrade to cpu's which use the same socket
    2) the chipset. You can research the chipset on the chipset manufacturers site to see what it supports
    3) the bios. Usually its hard to know what the bios supports, but knowing the machine model is very helpful since there are many users here, and someone is bound to have the same laptop.

    the i945PM chipset you have does have support for all socket M cpu's
    Your upgrade path is the same as the original posters.
    You can upgrade to any of the cpu's listed in post #4.

    What is the model of the system that you have?
    Knowing the model will help us determine whether the bios in your system actually supports the core 2 duo's or not.

    It is an Acer travelmate 8204.


    Are there really significant speed advantages from using a higher processor speed but still having the lower FSB?
