Hardware test is reporting that the onboard RAM on a 17" iMac G5 (iSight) is bad. It's out of warranty, and I'm happy enough dismantling it if I have to, so is there any way to remove/replace/disable the built in 512MB module?

    No, I don 't think you can remove it - you can add up to 2GB in the other slot, though. You don't need to open it to replace the RAM, there's a small compartment on the bottom that has a couple of screws in it. Just open it up and remove the existing stick and replace it, making sure you hear a click when you insert it.

    Thanks, but wouldn't it still try to access the onboard RAM and keep crashing?

    Sorry, didn't catch that it was the built-in RAM that was bad. You probably will have to take it in to an Apple service center, i have no idea whether you can replace it yourself.

    Pleasee post back and let us know what happens,

    Unlike some other iMacs the iMac G5 (iSight) has the 512MB soldered to the logic-board. Replacement is not possible except by replacing the entire logic-board at significant expense.

     

    Are you actually suffering any issues with the iMac that caused you to run Hardware Test?

     

    cheers

    The system was having kernel panics, so I ran the test. I ran it again last night and everything showed as OK, but then when the test finished half of the screen was taken up by scrolling text showing an openfirmware error. The machine now does not boot/chime - it starts, and a very very faint beeping can be heard coming from the superdrive I think. The internal LEDs 1 & 2 light, but 3 does not.
