    Hi,

    I have a laptop with a t5500 processor and a 945pm chipset. And I'd like to know up to what intel txxx processor I can upgrade this?

    Thanks...

    You can get a T7200, T7400, or T7600.

    Thank you for your reply ;-)

    If you don't mind, is it because of the 667FSB they all share in common? If so, can 800FSB processors be operated underclocked within same board? (I've done this before with PC memory.)

    I did a little research on mobile processor prices and found out that 800FSB processors are much cheaper (-100$) than 667FSB processors within close speeds. Does anyone know why?

    Thanks...

    The Socket P processors won't fit into your laptop. They're cheaper because the M's have been discontinued, and thus their prices no longer fluctuate.

    what kind of performance gain are you looking for? I would upgrade your ram before i did the processor. Most core 2 duos are more than powerful enough.

    Thank you all ;-)...

    I've researched wikipedia for Core 2 Duo's yet not paid attention for Socket P/M distinction. Now everything is clear. Thank you again...

    I have a Toshiba P100-43x = T5500 + 7900Go + 2GB 667 Ram(modified) + 200GB 7200rpm HDD(modified) + XP Pro. For me the weakest link within the computing power chain seems to be the T5500.

    System is adequate for most needs yet I've got quite much DVB-"video encoding" jobs where a higher processor will be better AFAIK. I expect that 3-4GB ram will only help Windows and memory hungry operations yet won't increase encoding speeds...

    Thanks...

    DVB encoding would definitely benefit from a faster processor. Rarely do I recommend a Core 2 faster than 2.0GHz to anyone, but for what you are doing you might benefit from a T7400 or even a T7600!

    OK, updating the current situation;

    I found T7400 version of my laptop within the same series-subseries sharing the exact same BIOS. I wrote in Toshiba forums about same situation yet many answered "NO", "IMPOSSIBLE", "Give Up" kind of answers. One 'kind' user replied;

    And I've found the following;

    Taking apart Toshiba Satellite P100 notebooks;
    http://www.laptopka.com/category/toshiba-satellite-p100p105/

    Toshiba P100 service manual;
    http://www.laptopmanualsnow.com/#Toshiba

    Now I know some of the answers:
    * how to disassemble -> service manual or site
    * if the CPU is soldered -> it's not, shown on site
    * if the chipset is compatible -> yes it is from Intel's
    * if new CPU produce more heat -> no it's not cos same

    * if the BIOS can handle the new CPU and if the fan table which stored in the BIOS would provide the compatible settings to cool the CPU correctly;
    -> Correct me if I'm wrong but a T7400 version with the same BIOS ensures all these.

    * if the microcode must be updated (only by an ASP) because the wrong DMI info will not allow the CPU to run with full performance.
    -> This should also be OK by the previous answer since AFAIK microcode is a part of BIOS and sharing the same BIOS ensures it.

    So, sorry to ask again but considering T7400 is $400+ purchase, are these justifications are true? Or am I wrong/incomplete about these information?

    Thanks for replies...

    P.S: The differences between subversions are: T5500 vs T7400, hdd capacity and screen resolution. All other things; chipset, gpu, dvd, wifi & etc. are identical.
