Single rank vs. dual rank and rank interleaving

[magellan]

Does memory rank interleaving make any noticeable difference in benchmarks or system performance? Please note I'm not writing about channel interleaving, but rank interleaving (which can be done on a single DIMM).

Does rank interleaving or number of ranks (I think there can be up to 4 ranks on an individual DIMM) on a DIMM make any differences in the ability to overclock a given DIMM?

A quote from a random google result:

Rank Interleave: Interleaves physical ranks of memory so that a rank can be accessed while another is being refreshed. Performance gains again depend on the benchmark in question. For 24/7 systems using triple-channel memory configurations there is no advantage to setting this value below 4 while Channel Interleave should be left at 6 for best overall system performance.

I remember setting it but don't think I ever did testing to confirm.
