For quad-channel setups&dual-rank memory: better performance?

[80251]

I've read articles about dual channel systems exhibiting higher performance with dual-rank DIMM's (or even 4 single rank DIMM's). Does this also extend to quad-channel setups?

Not necessarily. 4 dual rank DIMMs becomes effectively quad rank (per channel), at which point you might be putting enough strain on the memory controller that gains are likely to be minimal. You might even lose performance as the IMC had to work that much harder to organize everything. YMMV, in other words. But consumer memory controllers generally aren't designed for operation with more than two ranks, so aiming for two dual rank DIMMs or four single rank ones is likely the best approach.
