I don't know for sure, but I still assume (and hope) that there's a physical difference. I mean, I assume that the reason why memory can be sold at the speed and timings that it's at may be that it's the highest they could get it while still only requiring 1.5V. So that's why I think that you may need to increase the voltage if you match the clock and timings of the 1866 MHz 9-10-9-28 memory.
So I'm assuming that if they would have sold your memory at 1866 MHz 9-10-9-28, then it might have a stock voltage of 1.65V - I'm not sure. I think I'm assuming that it has to do with the chips and everything else on the PCB that makes up what we call the "memory module" or "DIMM" (Dual In-Line Memory Module).
