The Dual Inline Memory Module (DIMM) is the current standard circuit board used for desktop and server RAM.
|DIMM SDRAM||168 pins|
|DIMM DDR||184 pins|
|DIMM DDR2/DDR3||240 pins|
|DIMM DDR4||288 pins|
The Small Outline Dual Inline Memory Module (SODIMM) is a smaller version of a DIMM that is mainly used in laptops.
|SODIMM SDRAM||100 pins|
|SODIMM DDR/DDR2||200 pins|
|SODIMM DDR3||204 pins|
|SODIMM DDR4||256 pins|
The MicroDIMM is the smallest version of a DIMM and it is used where space is extremely limited, such as in subnotebooks or small form factor computers. There is currently no DDR4 version available.
The Rambus Inline Memory Module (RIMM), also referred to as Direct Rambus Dynamic Random Access Memory (DRDRAM or RDRAM), was intended to replace SDRAM DIMMs. It later lost out against DDR SDRAM due to having high latency and heat output.
The Single Inline Memory Module (SIMM) was the first RAM circuit board. There were two non-proprietary versions with different pin counts. It was created to make the installation of RAM easier by having all of the chips on a small removable circuit board instead of on the motherboard.
|SIMM||30 or 72 pins|
|RAM||Random Access Memory|
|DRAM||Dynamic Random Access Memory|
|SRAM||Static Random Access Memory|
|SDRAM||Synchronous Dynamic Random Access Memory|
|DIMM||Dual Inline Memory Module|
|SODIMM||Small Outline Dual Inline Memory Module|
|MicroDIMM||Micro Dual Inline Memory Module|
|RIMM||Rambus Inline Memory Module|
|SIMM||Single Inline Memory Module|
|DDR||Double Data Rate|
|SDR||Single Data Rate|
