240-pin DIMMs are used in DDR3 memory for desktop computers. DDR3 is the latest generation of memory with an improved architecture that allows it to transmit data more quickly.
A dual inline memory module (DIMM) consists of a number of memory components (usually black) that are attached to a printed circuit board (usually green). The gold pins on the bottom of the DIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a DIMM are not connected to each other.
Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered or Fully Buffered modules). Standard DDR3 240-pin DIMMs are currently available in DDR3 PC3-8500 SDRAM. Additional speeds will be added as the technology becomes available.
To use DDR3 memory, your system motherboard must have 240-pin DIMM slots and a DDR3-enabled chipset. This is because a DDR3 SDRAM DIMM will not fit into a standard DDR2 DIMM socket or a DDR DIMM socket.
The number of black components on a 240-pin DIMM can vary, but it always has 120 pins on the front and 120 pins on the back, for a total of 240. 240-pin DIMMs are approximately 5.25 inches long and 1.18 inches high, though the heights can vary. While 240-pin DDR3 DIMMS, 240-pin DDR2 DIMMs, 184-pin DDR DIMMs, and 168-pin DIMMs are approximately the same size, 240-pin DIMMs and 184-pin DIMMs have only one notch within the row of pins.

Will ecc memory work on a non ecc motherboard?
ECC Memory has an extra chip on the memory that performs Error Checking and Correcting functions. It's really only recommended for machines being used as servers.
For home systems, non-ECC memory is recommended unless you KNOW you need the ECC function. This is because ECC and non-ECC memory can almost always be mixed in the same system with no problems. If you mix these types of memory, the system will run as if all the memory was non-ECC.
Non-ECC memory is also recommended because it runs a little faster than ECC memory since it doesn't need to do the extra error checking. ECC memory is only really beneficial if you're going to be processing massive amounts of data (like a server does) and all data needs to be 100% accurate. Non-ECC is all that's needed for 99% of the computers out there.
