Types of DIMMs are DDR3 and DDR2 that have 240 pins, DDR DIMMs with 184 pins and SDRAM DIMMs with 168 pins.
686 pins
168 pins are used on SDRAM DIMM. 184 pins are used on DDR DIMM. There are either 30 pins or 72 pins used on SIMM. 184 pins are used on RIMM.

DIMM. Two types of DIMMs: a 168-pin SDRAM module (top) and a 184-pin DDR SDRAM module (bottom). Note that the SDRAM module has two notches (rectangular cuts or incisions) on the bottom edge, while the DDR1 SDRAM module has only one.
dimm
A DIMM is based on two different pin counts. SDRAM has 168 pins and is an earlier generation of RAM. DDR RAM has 184 pins. Both are considered DIMMS.
2.66" 200-pin SO-DIMM contains DDR2 SDRAM. One notch is near the side of the module.
