Interface Handbook page of the Altera website..
DDR3
The development board supports a 16Mx72x8 bank DDR3 SDRAM interface for very
high-speed sequential memory access. The 72-bit data bus comprises of four x16
devices and one x8 device with a single address or command bus. This interface
connects to the vertical I/O banks on the top edge of the FPGA.
The DDR3 devices shipped with this board are running at 800 MHz, for a total
theoretical bandwidth of over 1115.2 Gbps. These devices run at a minimum
frequency of 303 MHz.
