What is a DIMM?
A DIMM (Dual Inline Memory Module) comes in sizes from 8MB to 1GB (currently) and is twice the bit path of a SIMM. This allows for only one DIMM instead of two SIMMs to make up the 64-bit data path. DIMMs are typically made in packages of 72 pin, 144 pin (SODIMMs for portables) and 168 pins (Desktop, workstations and servers).
