    Hello,

    I want to replace a pentium M in socket PPGA478 for another CPU (notebook: SONY Vaio VGN-S1HP). Is it possible to install a faster CPU (do atoms fit?) or a cpu that consumes less battery and dissipates less heat?

    thanks in advance

    You need a socket 479 CPU with 400MHz FSB. Yes, it is possible to install a faster CPU. However they all consume same power as yours. And, nope, Atoms don't fit.

    - Pentium M 715 (1.5 GHz) - yours
    - Pentium M 725 (1.6 GHz)
    - Pentium M 735 (1.7 GHz)
    - Pentium M 745 (1.8 GHz)
    - Pentium M 755 (2.0 GHz)
    - Pentium M 765 (2.1 GHz)

    All these CPU's have a TDP of 21W.

    If I were you, I would upgrade to a 755.

    Since these are pretty outdated CPUs, it should not cost much at all. And you would get a 33% boost in frequency (1.5GHz -> 2.0GHz)

    Is this one of the Dothan's on a (I think) 400 mhz FSB motherboards. What I'm getting at is the "pin mod" that was widely used and easy to install. I did it on a Dell M90 or a D600 and it made an enormous difference and ran very stable with no heat issues. Just goggle it!

    I'm selling a 1.8 gigz Dothan that should work in your notebook in the marketplace :)

    Unless you are hitting 100% CPU usage chances are a CPU upgrade will not help you any.

    Pentium M's undervolt really well, to the point that they dont need any active cooling at all.

    Are you sure it was a D600? I'm asking because the D600 has a intel 855PM chips which supports 400 Mhz FSB only.

    I did the pin mod on a Dell Preceison M20/Latitude D610 :)

    I highly suggest you undervolt it. You will also get another 30mins+ of battery life. Heres my stress test results:

    Compaq M2000
    -Pentium M 725 1.6ghz
    -768mb RAM
    -40gb 4200rpm HDD
    -WinXP Pro

    Stock Max Voltage: 1.340v
    Rock stable Undervolt: .988v

    Massive .352v drop at full throttle. 55c max temp

    Stock Idle Voltage: .988v
    Stable Undervolt: .700v

    .288v drop at idle

    I will keep my 715 which I undervolted to 0,700V / 600Mhz and 0,908V / 1500Mhz..The fan does not turn on at all :)

    Pin modding does not work with my chipset.
