hi all, I have an old notebook and i want to upgrade cpu. I find a ciryx gp100 100mhz socket3 cpu. this cpu need 3,45 volt but the old cpu uses 5 volt. I don't know where(if there are any) the jumper to select voltage is on the mainboard. I don't know the type of mb and the mainboard code for looking on the net for more info. any suggestions? thanks in advance for your replies. Bye
Look for a web blog or discussion group that focuses upon old laptops like yours.
If your laptop has a genuine 'socket 3', you could use an interposer from a variety of companies such as Evergreen, Powerleap, etc. I have a number of small 486 machines upgraded to Pentium (up to 166 MHz) using interposers and AMD or Cyrix cpus. The interposer has active circuitry to provide cpu voltages and glue logic. Make sure your laptop has sufficient clearance to accommodate the height of an interposer -> cpu -> heatsink(fan, cooling pipe, etc.).
Regards,
Michael
Why even bother? Unless you have the CPU laying around, it's hardly worth the effort. You can get a far more capable laptop for relatively little money these days.
