CPU Compatibility

  1. I was curious that if I start out with a Pentium 4-M 1.7 GHZ CPU which uses the Intel 845MP chipset, would I be able to use a CPU such as a Pentium M (Socket 478, of course) when the Pentium M needs the 855 chipset series?

    If they both have the same Socket then they will work ;)

    If your CPU's chipset is not supported by your motherboard's chipset, then they are not compatible.

    This means if your motherboard only supports the Intel 845 chipset, and you get a CPU that needs only the 855 chipset, then they will not work!

    Sometimes updating the BIOS will enable the motherboard to support more modern processors, but not all the time, since the hardware (the chipset) influences more on which CPUs it can support.

    A more effective way of answering your question even further would be possible if you tell us the name of the motherboard and the exact model of your Pentium M. Links would help with this.

    I don't know the motherboard, but it's for a Compaq Evo Notebook N800c and the CPU is an Intel® Pentium® M Processor 1.40 GHz . I hope that helps any. All I could find online was that this laptop's mobo had the Intel 845MP chipset in it and I found on Intel's site that Pentium Ms require the 855 chipset. I'm hoping I could get around it; if not there's always ebay :haha:
