It only supports up to a 533mhz front side bus(fsb)
since you have a dothan(newer) just look for a p4m (m for mobile) processor with a 533fsb and probably without HT and under 2.8ghz to be safe (i cant say a 2.8 will work or not but at least you have a direction)

btw any penium 4 m is faster than the celeron you have
another thing heat will be higher, clear dust and use tiny amount of arctic silver 5
and battery time will be down

    Toshiba Satellite C655D-S5084 CPU upgrade

    It is possible but usually not worth the hassle.
    Changing to another CPU chip that fits your motherboard may only show a 3-10% performance change.

    See videos of CPU replacement in laptops like yours:

    In general, you are better off adding more RAM (memory) or replacing the hard drive with a faster SSD (Solid State Drive) to make a laptop "fly". Your laptop can hold a max of 8 GB RAM:

    In MOST laptops, slower 5400 RPM drives are used, and this is the main performance bottleneck. A 7200 RPM drive or (better yet) a SSD drive will help matters, as will more RAM (the most cost-effective speed increase).

    Hard drive hums and computer will only work when the cpu is 90degrees to the surface it is sitting on.

    Make a good backup of all your files, before the disk-drive (or the motherboard) completely "dies".

    Then, take your computer to a Toshiba-approved technician, for professional trouble-shooting.

    Can I install a better CPU into my Toshiba Satellite P305D-S8834 17 1 Widescreen Notebook Computer then the AMD Turion X2 Processor RM-70 it came with?

    Changing CPU is a serious change. When your unit was built the processor speed and type were written into the BIOS. When we change the CPU to a different type there is a chance that the BIOS will not recognize it and refuse to boot up. Also Windows was installed with the original CPU and a major change in hardware could mess up Windows.

    I did some research and found this model comes with a 2.0-GHz AMD Turion X2 Dual-Core RM-70 CPU and 4GB of RAM. This is not the fastest CPU that can be put in a laptop but a very good one. (faster than mine)

    I can guide you through the steps to replace it but my advice is stick with what you have until it breaks and buy a faster laptop. The upgrade won't gain you enough to justify the expense.

    Changing the stacks setting can be done by editing the config.sys with any editor such as notepad. However, I doubt doing this will solve anything. A stack overflow error is usually a CPU chip problem.

    Changing CPU in HP PAvilion 6745C PC DESKTOP

    Your PC is now installed with Intel Celeron 700 MHz (socket 370), which is maximum suggested by HP. Instead you'd better upgrade memory up to 512MB.
