SO DIMM – What does SO DIMM Mean?
A SO-DIMM, or small outline dual in-line memory module, is a type of computer memory built using integrated circuits.

SO-DIMMs (also written SODIMMs) are a smaller alternative to a DIMM, being roughly half the size of regular DIMMs. SO-DIMMS are often used in systems which have space restrictions such as notebooks, small footprint PCs (such as those with a Mini-ITX motherboard)
How do you compare SO_DIMM DDR, SO DIM DDR2 and SO-DIMM DDR3 for laptops PCs and Macs?
Most types of SO-DIMMs can be recognized at a glance by the-DIM distinctive notches used to “key” them for different applications:
- 100-pin SO-DIMMs have two notches,
- 144-pin SO-DIMMs have a single notch near (but not at) the center, and
- 200-pin SO-DIMMs have a single notch nearer to one side. The exact location of this notch varies. (See below.)
What are some of the variants of 200-pin SO-DIMMs
The 200-pin SO-DIMM notch is in one of two locations.
- If the notch is located away from the center, it indicates the DDR class of memory.[citation needed]
- When the notch is located nearer the center of the board, it generally (but not always) indicates that the RAM is of the DDR2 type.[citation needed]
These two types of memory are not interchangeable. The different notch locations are designed to prevent cross-installation. Keep this in mind when attempting to visually identify 200-pin SO-DIMM modules.
What is the size of SO-DIMM Ram? – This Ram measures 6.36 cm in length and a width of 3.175 cm with a maximum total depth of 0.38 cm.
DDR2 SO-DIMM memory modules can clock speeds from 200 MHz up to 800 MHz PC2-6400
SO-DIMMs are equal in power and voltage rating to DIMMs, and as memory technology moves forward and despite their smaller size, SO-DIMM technology allows for performance speeds as high as the those of larger DIMMs.
The latest 204-pin SO-DIMMs can contain DDR3 SDRAM, with specifications such as PC3-6400, PC3-8500, PC3-10600, and PC3-12800
