50 Chapter 4 Installing Memory
8 Press the memory module gently into the compartment to lock it in place. You will hear
a slight click and the two rings will automatically fold part way into the slot when the
memory is seated correctly.
9 Replace the memory access door using it to push the rings into the memory
compartment. Use a Phillips #2 screwdriver to tighten the screws.
Warning: Always remember to replace the memory access cover after you have
finished installing memory. Your iMac G5 will not function properly without the
memory access cover.
