I have that Cyclone III board, but didn't use all the memory there. I also have Stratix II GX board, where the memory is organized in the same fashion.

A14 and A15 pins I've mentioned are not FPGA pins, these are DDR address bus pins A14 and A15 (last address bits).

P.S. I've also used ECC there, so don't know if it is easy to set up without ECC enabled.
