240 pins, or actually connections on a DIMM, dual inline module.
ddr1 184 pins ddr2 240 pins ddr3 240 pins there are 240 pins one side 120 pins and other side 120 pins so 120+120 = 240 pins in ddr2 ram. as well as ddr3 has 240 pins and ddr1 has 184 pins only . by Prem verma from www.prem-verma.blogspot.com
6they guy who writ this is a . t . w . a . t ., the answer is 240!!!
DDR1 RAM typically has 184 pins and a notch located closer to the center. DDR2 RAM has 240 pins and a notch positioned more towards one side. You can also look at the labeling on the RAM module itself to identify whether it is DDR1 or DDR2.

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.
There are 2 easy ways. No#1- Downlaod a 'system analysis' tool (e.g. CPU-Z) run the progamme and check its window. http://www.cpuid.com/cpuz.php No#2- Open the case, and look at the ram slots. DDR1 has 184 pins, DDR2 has 240 pins. The 'notch' in the ram stick is also in different places on DDR1 vs DDR2. After you have look at a few ram sticks, you can soon pick the difference between DDR1 amd DDR2, but in the beginning it is no so easy. There is quite often a sticker on the side of the ram telling you what type/speed it is to make things easier, but it can be hard to see inside the case. DDR1 also ranges from DDR-200 (PC-1600) to DDR-433 (PC-3500) and DDR2 ranges from DDR2-400 (PC2-3200) to over DDR2-1066 (PC2-8600)
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
DDR. Technically, there is no "DDR1", only "DDR" and DDR2".
In DDR1 the Chip is in Rectangle shape and DDR2 the Chip Shape is in Square and DDR2 is Chip smaller than DDR1.DDR1 is centre cutting 7.5cm.DDR2 is centre cutting 7cm.DDR1 pin 92. DD2 pin 122.DDR1 pin is larger than DDR2.
