Can Altera FPGA support DDR2 or DDR3 interchangable memory of PC?

I want my board to support DDR2 or DDR3 PC memory through standard memory slot.
The FPGA should support most kinds of memory in stock.

However when I tried to config DDR2 or DDR3 memory controller by QSys,
it seems that it only support one kind of DDR timing through specified parameters.
Does it applicapable to support different type of DDR with one DDR controller?
