There are 240 pins on DDR2 and DDR3.
686 pins
6they guy who writ this is a . t . w . a . t ., the answer is 240!!!

240
count them
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
2.66" 200-pin SO-DIMM contains DDR2 SDRAM. One notch is near the side of the module.

All DDR chips have 184 pins while DDR2 have 240 pins
For server and high end stations nimber of pins are 240. For Laptop and Cube PC it is 214. (Refer Simmtester.com-Publications)
Here's what I found out for you. The DDR3 has 240 pins just like the DDR2, however, they will not be compatible, you will not be able to put a DDR3 into a DDR2 slot. The knotch on the stick of RAM is in a different location so it will not fit. So a new motherboard made for DDR3 will have to be used. They are currently out on the MAC Lite computers but not sure if Microsoft has any on the market yet. The DDR3 will use 1.5V, which is lower than the DDR2 1.8V.
DDR2 DIMMs have a total of 240 pins. The pin configuration includes a notch on the bottom edge to ensure proper alignment when inserted into a motherboard. Pins are arranged in two rows, with specific pins designated for power, ground, data, and control signals. DDR2 also features a different keying mechanism compared to its predecessor, DDR, to prevent incompatible installations.
Types of DIMMs are DDR3 and DDR2 that have 240 pins, DDR DIMMs with 184 pins and SDRAM DIMMs with 168 pins.
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.
RAM with 240 pins typically refers to DDR2 and DDR3 SDRAM DIMMs (Dual In-Line Memory Modules). These types of memory modules are commonly used in desktop computers and are characterized by their 240-pin configuration. DDR2 and DDR3 differ in speed and performance, with DDR3 offering higher bandwidth and efficiency compared to DDR2. However, they are not interchangeable due to differences in their electrical specifications and physical notches.
The number of pins at the bottom of the stick. Some ddr's have 184 pins, some newer models have 240, starting with DDR2.
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)
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.
If you mean which kind is already in your computer, going to your start menu to Accessories and opening System Tools, then System Information gives you an overview of what kind of components your computer is utilizing. You can also go to your manufacturer's website and look up your model. As for telling the difference between the memory you're looking at outside of the computer, usually when you buy the RAM it will have DDR2 or 3 in the name of the component itself. DDR2 RAM has either 200 or 240 pins on it (the little gold metal "legs" sticking out of the component) though this is something of a bother to count. The number of pins is the same on both sides though, so if there are 100 or 120 pins on one side, it's DDR2.
Unfortunately not. DDR has a different amount of pins compared to a stick of DDR II. Also the slot position is slightly different. Hope this helps Be Safe Cadishead Computers
