First of all you can not use 2 chip select cause the DDR2 you are using doesn't support two chip select.
Second, the automatic assignment you are talking about are pre-assigned since you are using the "standard" template.
Finally, I am having the same problem when I am trying to increase the data width to 64-bit, it's something I cannot figure out!

Thank you!
I build a new project, it only contain cput, jtag uart and ddr2 sdram, I am not using the "standard" template.but the quartus still automatic assigg the pins. If quartus didn't assign the pins automatically,and I finish the pins assigment manually, I will get an warning in "Filtter" process,the waring is something about "capacitance",and I can compile this project succefully,but I can't run "hello world" on it.
