These are usually populated by default, but can be removed if necessary. This allows more RAM to be installed if the system requires it. However, the amount of available RAM is still limited by the maximum capacity of the slot. This is often less than the total amount of RAM in the system. This is because the system must allocate some of its RAM to the operating system and other essential programs.
