Key Features Increases laptop performance Easy to install Compatible with OEM systems 100% component & module tested for superior reliability Notebook modules that operates at speeds up to 1600 MT/s & has a CL11 latency. It is dual voltage & can operate at 1.35V or 1.5V. It is Unbuffered & is non-ECC. It conforms to the industry standard SODIMM layout of 204 pins & is compatible with computers that take DDR3 SODIMM memory. To use DDR3 memory, your system must have both a 204-pin SODIMM slot & a chipset that supports DDR3 memory. A DDR3 SODIMM will not fit into DDR2 or DDR memory sockets. SODIMMs are smaller & thinner than regular DIMMs, & the 204-pin SODIMM PCBs are always ~2.6 inches long & are usually around 1.18 inches high (though the heights can vary slightly). They consist of a number of memory components (usually black) that are attached to a printed circuit board (usually green). The number of memory components on a 204-pin SODIMMs printed circuit board (PCB) can vary, but the PCB will always have 102 pins on the front & the back both, for a total of 204 pins. The gold pins on the bottom of the SODIMM provide the connection between the memory module & the memory socket.
