Edge Memory - D5240-230760-PE

DDR3 SDRAM – double data rate type three synchronous dynamic random access memory, yields a high bandwidth interface, a standard that permits chip capacities of up to 8 gigabits, and an ability to transfer data at twice the rate than its immediate predecessor, DDR2 SDRAM. Speeds can reach up to 8 times the speed of its internal memory arrays, raising its peak data rates. Two transfers per cycle of a quadrupled clock yield a 64-bit DDR3 module a transfer rate of up to 64 times the memory clock speed in MB/s than a comparable DDR2 module. DDR3 SDRAM is not directly compatible with either of its predecessors, DDR2 or DDR due to several factors including different signaling voltages and timings. DDR3 DIMMs house 240 pins, DDR3 SO-DIMMs 204 pins. Different key notch positions on the DIMMs prevent the two interchanging.
