RAM MEMORY DDR, DDR2, DDR3.

DDR

Modules are composed of synchronous memories (SDRAM), available in encapsulated DIMM, which allows data transfer for two different channels simultaneously in the same clock cycle.

DDR2

The DDR2 memories have higher latencies than those achieved with conventional DDR, which harmed their performance. Reduce latency in DDR2 is not easy.

DDR3

These modules can transfer data at a rate of 800-1600 MHz Effective Clock, compared to the current range of DDR 2 533-800 MHz or 200-400 MHz DDR.
