    PowerMac G5 RAM Installation
    So I'm having some odd occurrences while installing new RAM into my G5.

    I originally had 512 mb and installed an additional 512. However, my System Profiler still shows my Memory at 512 mb.

    Also, my system will only boot up if I leave the original RAM cards in their original spots. Otherwise, when I turn the machine on the light on both the computer and the monitor will simply blink twice over.

    My question is why does my System Profiler still show my Memory at 512 mb? I'm fairly certain the installed RAM was good being that I just opened it.

    Cool
    First question is the additional memory 2 stick of 256 equaling 512 or is it 1 stick of 512?

    On the Powermac G5 you will add memory sticks in pairs. Meaning if you are adding an additional 512, then you need to sticks at 256.

    Okay, then your system should have come with 2 256MB memory stick also. There should be two banks for the memory to be inserted into. Since you now have four memory sticks, two will go into the one bank and the remaining two will go into the other bank.

    Will have to get back to you on the slot numbers, to use. if you did not take out the original memory, just place one behind each of the original memory stick.
