Pin assignment De-1 SoC board

Hi Altera forum, I was trying to use certain pins on my dev board, but Quartus tells me it cant assign the 25MHz clock and DDR3 pins "they are reserved for the programmer pins". Which is bogus ...

Ofcourse it was foolish of me to believe that would solve my troubles. The thing is it's connected to the DDR3 ram module on the board and I can only guess it needs an on chip termination IP.

Must be the soul reason the pins aren't planned in the golden top module. But at the frequencies im running it at it's no different from the other stuff im running it at.. So are there any workarounds to this issue?
