    Hi there! (^_^)

    On the eMac manual says that the maximum capacity is 1Ghz = 2x 512MB chips.

    Is that really true that I can place 2x 1Ghz chips? Will really work?

    Anyone tested?

    Yup, provided you have the right model eMac and the right RAM, it'll work.

    The right eMac model? I don't get it. (?_?)

    My eMac: G4, 1GHz, 128 (Now 640), 40, Combo (now SuperDrive), 56K

    OK, to be more specific:

    The eMacs with USB 1.1 and PC133 RAM are limited to 2 x PC133
    700, 800 Mhz and 1 GHz
    M8577LL/A; M8578LL/A; M8578LL/B; M8655LL/A; M8655LL/B; M8891LL/A; M8891X/A; M8892LL/A; M8892X/A; M8950LL/A; M8951LL/A; M8951LL/B; M9150LL/A; M9252LL/A

    The eMacs with USB 2.0 and DDR RAM can go to 2 x 1 Gb PC2700 DIMMs
    1 Ghz, 1,25 GHz and 1.42 GHz (despite the original Apple specification saying 2 x 512 as the max)
    M9423LL/A; M9424LL/A; M9425J/A; M9425LL/A; M9461J/A; M9461LL/A; M9834LL/A; M9835LL/A; M99832; M99833; M99834; M99835

    Notice there is an overlap in the 1 GHz models, so you really do have to check the specifics of the machine if you have a 1.0.
