A question about the block memory

I used 82% of the total block memory bits. However, Quartus cannot place all RAM cells in design. The FPGA device which I am using is EP3SL150. Please tell me, what is the problem? How to successfull...

Yes, I used the Megawizard to generate the RAM. I tried to used the M9K by 36*3+18+2=128-bit. However, it also cannot work. M144K blocks only have 2,359,296 bits. I need 128*32768=4,194,304 bits.
