    Upgrading B130 CPU - Need Help w/Stupid Idea

    OK, here's the situation. Promise not to laugh.

    Some time ago, I bought a 3GHz Prescott CPU to upgrade my aging desktop computer. I soon realized that its motherboard isn't actually compatible with such a new (*snicker*) CPU, and as such I couldn't use the thing for this purpose.

    Recently however, I realized something else: my Dell Inspiron B130 laptop has an Intel 915-chipset motherboard, and is so technically compatible with the Prescott chip. Which has led me to an interesting idea: why not install the chip in my Celeron-powered laptop and give that an upgrade instead?

    Well, it might also be a really, really stupid idea as well, given that we're talking about a relatively high-powered desktop CPU running on a laptop. Battery life is not an issue in my situation (I'm plugged in 99% of the time that I'm using this), but can the B130 actually take such a chip? And if so, would I need to get some kind of monstrous 3rd-party heatsink to keep my beloved lappy from bursting into flames with a CPU over four times the Thermal Design Power of its original processor?

    Strange question, I know. But this seemed like a good place to ask it.

    Even if it does fit, the main problem will be heat. In desktop case you have much better ventilation and cooling then in a laptop. So a desktop CPU might(probably will) fry your laptop.

    OK, that's what I thought. Thanks.

    The Prescott chip has 775 pins, and the notebook 915 chipset has 478 or 479 (I don't remember which). It's not a matter of heat, it just cannot fit.

    LOL..I'd invest in a high quality cooling pad and take it wherever you go and whenever you use your laptop. It might work like that then..(if it even fit).

    Nono, I have a 478-pin edition of the chip (check the link :D ). However, given what other people have said I have a feeling it'd be a bad idea anyway. Oh well. ;)

    The other thing is bios support (speeds, instructions, and such), there are more differences in MBs than just pin #s and thermal design.

    If it does in fact fit and work you could put it in and underclock.
    Start it out at a very low clock 1/4 speed or less. Then gradually increase as you CLOSELY monitor the temps under various loads. I doubt you would approach the same performance before you exceed the notebooks cooling ability but it would be very cool to find out.

    Actually the main limitation is power! Your power supply and electronics are not designed to feed such a chip I'm sure, and even if the bios supported it and the heat could be dealt with (very unlikely), you'd probably kill your power supply and possibly the MOBO very quickly when it tries to draw 90 watts from a 40 watt supply!

    I agree with Cheffy. I was going to post the same thing.
    Unless your laptop came with versions that had Prescotts there is no way it will be able to handle such a power consuming chip.
