DDR SDRAM uses 184 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.
No, they're not cross compatible. 184pin DDR is desktop memory, 200 pin ddr is a SO-DIMM, which is laptop memory.
All DDR chips have 184 pins while DDR2 have 240 pins
The EDO RAM desktop memory modules have 72 pins and operate at 5V as standard

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.
The number of pins at the bottom of the stick. Some ddr's have 184 pins, some newer models have 240, starting with DDR2.
DDR 1 USE 184 PINS THE BEST THING IS TO TAKE DDR AND CHECK THE PIN AREA THAT IS GOLD PLATED YOU WILL FIND WRITTEN 1-96 AND OTHER SIDE 97 -184 THAT MEANS YOU ARE USING DDR1 DDR 2 USE 240 PINS SAME THING FOR DDR2 AND IT WRITTEN 240 MUSTAFA AHMED KHAN DDR 1 USE 184 PINS THE BEST THING IS TO TAKE DDR AND CHECK THE PIN AREA THAT IS GOLD PLATED YOU WILL FIND WRITTEN 1-96 AND OTHER SIDE 97 -184 THAT MEANS YOU ARE USING DDR1 DDR 2 USE 240 PINS SAME THING FOR DDR2 AND IT WRITTEN 240 MUSTAFA AHMED KHAN DDR 1 USE 184 PINS THE BEST THING IS TO TAKE DDR AND CHECK THE PIN AREA THAT IS GOLD PLATED YOU WILL FIND WRITTEN 1-96 AND OTHER SIDE 97 -184 THAT MEANS YOU ARE USING DDR1 DDR 2 USE 240 PINS SAME THING FOR DDR2 AND IT WRITTEN 240 MUSTAFA AHMED KHAN
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.
Types of DIMMs are DDR3 and DDR2 that have 240 pins, DDR DIMMs with 184 pins and SDRAM DIMMs with 168 pins.
