Hi, There is no point for this "optimization" in the case of MD and GROMACS. MD doesn't occupy much memory because for each atom, only six variables (three coordinates and three velocities) are needed. Program code isn't that complex, too. Except you have a on-die cache like this large, memory size doesn't matter to the performance of MD.
Memory bandwidth is something matter. In recent post regarding Intel's Core 2 Duo in quad-core configuration, it shows that the benchmark doesn't double the dual-core configuration. It could be due to the limiting memory bandwidth that Intel platform provides.
