Regarding SDRAM Controller

Hi this is Sundaram from University of Waterloo. I'm working on a DE4 board from terasic. The Board came with a hynix DDR2 - SDRAM (S.no h5ps1g83efr-s6c). But, there are no hynix provided memory presets in the ddr2 sdram controller with altmemphy ip. So can you guys help with me the modifications that I need to do in some of the parameters of a memory preset. If you google the Serial Number of the RAM, you can easily find the data sheet. But, I don't know which parameters to modify in the available memory presets in the module.
