DDR3 Architecture Roadmap
DDR3 will become the widely adopted memory architecture for computingArchitecture in 2008.

DDR is in line with the computing architecture with the demand for HIGH SPEEDand LOWER POWER COMSUMPTION memory solution.

DDR vs DDR2 vs DDR3

DDR3 Advantage : High Bandwidth
DDR3 memory will provide at least twice the bandwidth of DDR2, with data transfer rates at up to 1.6Gb/s and eventually beyond.
Twice the Bandwidth
Page 5
DDR2 memory is specified for a 1.8V operating voltage while DDR3 memory operates at 1.5V (and maybe 1.35V in future low-power DDR3L devices). Because operating power is proportional to the square of the operating voltage, appreciable drop in operating power—about 30% less!
Really Power Saving

Why need the Narrow Latch ?
The server is ventilated by means of extractor fan and the air vents. The heat will be carried away through heat convection. The DDRX module and connector is close to each other due to the limited space. The heat flow was blocked by the connector housing and latch in the direction of heat flow. The narrow latch can increase the gap between connectors and it will be a great benefit to heat dissipation.

The latch with the smooth surface and the rounded edge can increase the velocity of air flow and this will be a great benefit to heat dissipation.

Why we need DDR3 1.35 V connector
With Low LLCR ,we can reduce the power loss to the maximum and so that fully support DDR3 1.35V module on the ideal performance
