SIMM Single In-Line Memory Module:
Older 286, 386, and 486 systems had 30 pin SIMM sockets.
Newer 486, and early Pentium motherboards had 72 pin SIMM sockets.
Later Pentium, Pentium II, and AMD K6 motherboards have 168 pin DIMM sockets.

All of which are basically obsolete now.
Almost all current motherboards use 184 pin DDR-RAM DIMM sockets.

If you have a 486 or an older Socket 7 (Pentium) motherboard, you "might" have both SIMM and DIMM sockets.

If you do have both sockets, there are assorted limitations as to mixing and matching memory types.

For Pentium systems, SIMM memory MUST be installed as matched pairs.
