I am having the same problem since ive upgraded to Quartus v9.1. But ive just found the true datasheet of the memory board by the chip number: HY5P81G831C FP-S5. The datasheet is in:

http://www.hynix.com/inc/pdfdownload.jsp?path=/datasheet/pdf/dram/hy5ps1g4(8.16)31c(l)fp(rev0.6).pdf (http://www.hynix.com/inc/pdfdownload.jsp?path=/datasheet/pdf/dram/hy5ps1g4%288.16%2931c%28l%29fp%28rev0.6%29.pdf)

Check if your board have the same chip. Im making the config file and ill test it tomorrow. If it works i will post it here.
