Adeel, I did some 3D modeling for a DIMM connector once, and I learned that it's important to pay close attention to the interconnect between the DIMM pad and the power and ground planes. This interconnect is for all practical purposes a part of the connector itself. In real life you can find quite different crosstalk numbers from what the coupled DIMM model alone would predict.

Also I'm interested in a website describing Electrical Features of common connectors (both plugs and sockets).
