RAM and system board
You can not freely install your desired RAM type. RAM is controlled by the chip set on the
system board, so you must install a type, which matches your system board. Furthermore,
RAM chips come in different sizes, which must match the system board.
On modern system boards, RAM is installed on SIMM or DIMM modules. Before, small
individual DRAM's were used. There was usually room for 36 small chips on the system board.
That made it cumbersome to install new RAM. Then, someone figured out to install RAM chips
on cards, which are easily installed. First came the SIPP modules. They had multiple pins,
which fit in the system board. Since came the SIMM modules. They are mounted on a card,
which has an edge connector. They fit in sockets on the system board, and anyone can install
them.
