    Hey folks. I'm new to the forums so "hi".

    Has anyone successfully swapped out a yonah (core solo or core duo) chip for a merom (core 2 duo) in an hp or compaq machine?

    I know the socket is the same and all and theoretically it should be possible but i want to hear from some one who as actually done it. I've looked on HP's website and i think it might be possible that the machines with the merom chips actually have different motherboards (as opposed to the same MB flashed w/ a different BIOS) even though all the ports are in the same place and they share chipsets. HP is just sinister enough to do something like that! The last thing i want to do is flash my bios and end up with a door stop.

    Another option: can someone with a merom chip post the make and model of your mother board? Use cpuID or pcwizard or something.

    thanks!

    Merom only requires a BIOS update for it to be compatible with Yonah based systems. They share the same socket & chipset(945PM/GM). So, as long as you have the latest BIOS you should be fine with the upgrade to Merom. Plus all notebokks in the same series(like dv2000t, dv6000t) share the same BIOS. The BIOS only differs between the series and between any major updates(like the dv2000t & dv2500t)

    So, if I have the latest BIOS update for my dv2037, are you saying i should be able to put in a T5500 without another BIOS flash? That would be worth a try i suppose. If it doesn't work, no harm done.

    Still, its only theory. I'd really like to hear of someone doing it. Maybe i'll have to be the first!

    Just keep in mind that the Core 2 Duos on the dv2500t/dv6500t/dv9500t are also Memrons, but they are Socket P and therefore incompatible. You will need a Socket M C2D to replace the Yonah.

    No as long as you have the latest BIOS for your system you should be fine and from what I can remember HP updated the BIOS to support the Meroms(Socket M as R4000 mentioned) sometime last year. Check the link below to see if there are any BIOS upgrade available for your system...

    You can check your current BIOS version by pressing Fn + esc keys or by booting into the BIOS itself.

    Actually, HP is doing it right now. If you go to the dv6000t CTO page and configure, you will see both Yonahs and Memrons in the lineup:
